158-471: The Piltdown Man was a paleoanthropological fraud in which bone fragments were presented as the fossilised remains of a previously unknown early human . Although there were doubts about its authenticity virtually from the beginning (in 1912), the remains were still broadly accepted for many years, and the falsity of the hoax was only definitively demonstrated in 1953. An extensive scientific review in 2016 established that amateur archaeologist Charles Dawson

316-429: A 238 cm (8 ft) yew spear was apparently lodged in an elephant. In Africa, 500,000-year-old points from Kathu Pan 1 , South Africa, may have been hafted onto spears. Judging by indirect evidence, a horse scapula from the 500,000-year-old Boxgrove shows a puncture wound consistent with a spear wound. Evidence of hafting (in both Europe and Africa) becomes much more common after 300,000 years. The SH humans had

474-597: A blood-like colour, though ochre can also have a functional medicinal application. Beyond these two species, ochre usage is recorded at Olduvai Gorge , Tanzania, where two red ochre lumps have been found; Ambrona where an ochre slab was trimmed down into a specific shape; and Terra Amata where 75 ochre pieces were heated to achieve a wide colour range from yellow to red-brown to red. These may exemplify early and isolated instances of colour preference and colour categorisation, and such practices may not have been normalised yet. In 2006, Eudald Carbonell and Marina Mosquera suggested

632-602: A female from Jinniushan , China; and 181.2 cm (5 ft 11 in) for a specimen from Kabwe , Zambia; around the same as modern humans . Like Neanderthals, they had wide chests and were robust overall. The Middle Pleistocene of Africa and Europe features the advent of Late Acheulian technology, diverging from that of earlier and contemporary H. erectus , and probably issuing from increasing intelligence. Fire likely became an integral part of daily life after 400,000 years ago, and this roughly coincides with more permanent and widespread occupation of Europe (above 45°N ), and

790-626: A female partial skeleton from Jinniushan is estimated to have been quite tall at roughly 165 cm (5 ft 5 in) in life, much taller than the SH females. A tibia from Kabwe is typically estimated to have been 181.2 cm (5 ft 11 in), among the tallest Middle Pleistocene specimens, but it is possible this individual was either unusually large or had a much longer tibia to femur ratio than expected. If these specimens are representative of their respective continents, they would suggest that above-medium to tall people were prevalent throughout

948-858: A foundation of big rocks and earth. Other such dwellings have been postulated to have existed during or following the Holstein Interglacial (which began 424,000 years ago) in Bilzingsleben, Germany; Terra Amata , France; and Fermanville and Saint-Germain-des-Vaux in Normandy . These were probably occupied during the winter, and, averaging only 3.5 m × 3 m (11.5 ft × 9.8 ft) in area, they were probably only used for sleeping in, while other activities (including firekeeping) seem to have been done outside. Less-permanent tent technology may have been present in Europe in

1106-409: A human skull together, but the odds of it happening twice were slim. Even Keith conceded to this new evidence, though he still harboured personal doubts. On 23 July 1938, at Barkham Manor, Piltdown, Sir Arthur Keith unveiled a memorial to mark the site where Piltdown Man was discovered by Charles Dawson. Sir Arthur finished his speech saying: So long as man is interested in his long past history, in

1264-458: A lakeside. The spears vary from 2.9–4.7 cm (1.1–1.9 in) in diameter, and may have been 210–240 cm (7–8 ft) long, overall similar to present day competitive javelins. The spears were made of soft spruce wood, except for spear 4 which was (also soft) pine wood. This contrasts with the Clacton spearhead from Clacton-on-Sea , England, perhaps roughly 100,000 years older, which

1422-594: A little more than two years, in the winter of 1929, Pei Wenzhong , then the field director at Zhoukoudian, unearthed the first complete calvaria of Peking Man . Twenty-seven years after Schlosser’s initial description, the antiquity of early humans in East Asia was no longer a speculation, but a reality. Excavations continued at the site and remained fruitful until the outbreak of the Second Sino-Japanese War in 1937. The decade-long research yielded

1580-728: A male. The only notable exception was the coverage by the Daily Express newspaper, which referred to the discovery as a woman, but only to mock the suffragette movement, of which the Express was highly critical. 50°59′16″N 0°03′46″E  /  50.98778°N 0.06278°E  / 50.98778; 0.06278 Paleoanthropology The field draws from and combines primatology , paleontology , biological anthropology , and cultural anthropology .

1738-427: A modern humanlike hyoid bone (which supports the tongue), and middle ear bones capable of finely distinguishing frequencies within the range of normal human speech. Judging by dental striations, they seem to have been predominantly right-handed, and handedness is related to the lateralisation of brain function , typically associated with language processing in modern humans. So, it is postulated that this population

1896-649: A new species, Ardipithecus ramidus , based on fossils from Ethiopia. In 1999, two new species were announced. Berhane Asfaw and Tim D. White named Australopithecus garhi based on specimens discovered in Ethiopia's Awash valley . Meave Leakey announced a new species, Kenyanthropus platyops , based on the cranium KNM-WT 40000 from Lake Turkana. In the 21st century, numerous fossils have been found that add to current knowledge of existing species. For example, in 2001, Zeresenay Alemseged discovered an Australopithecus afarensis child fossil, called Selam , from

2054-642: A new species, Australopithecus sediba , based on fossils they had discovered in Malapa cave in South Africa. In 2015, a team also led by Lee Berger announced another species, Homo naledi , based on fossils representing 15 individuals from the Rising Star Cave system in South Africa. New species have also been found in eastern Africa. In 2000, Brigitte Senut and Martin Pickford described

2212-534: A plausible motive—namely, revenge on the scientific establishment for debunking one of his favourite psychics—and said that The Lost World appeared to contain several clues referring cryptically to his having been involved in the hoax. Samuel Rosenberg 's 1974 book Naked is the Best Disguise purports to explain how, throughout his writings, Doyle had provided overt clues to otherwise hidden or suppressed aspects of his way of thinking that seemed to support

2370-692: A proposal to the Rockefeller Foundation seeking financial support for systematic excavation at Zhoukoudian and the establishment of an institute for the study of human biology in China. The Zhoukoudian Project came into existence in the spring of 1927, and two years later, the Cenozoic Research Laboratory of the Geological Survey of China was formally established. Being the first institution of its kind,

2528-476: A sequential lineage, with each species evolving into the next ( chronospecies ). Though later Mayr changed his opinion on the australopithecines (recognizing Australopithecus ), his more conservative view of archaic human diversity became widely adopted in the subsequent decades. Though H. erectus is still maintained as a highly variable, widespread, and long-lasting species, it is still much debated whether or not sinking all Middle Pleistocene remains into it

2686-467: A single human tooth from Beijing . Although Schlosser (1903) was very cautious, identifying the tooth only as "? Anthropoide g. et sp. indet ?," he was hopeful that future work would discover a new anthropoid in China. Eleven years later, the Swedish geologist Johan Gunnar Andersson was sent to China as a mining advisor and soon developed an interest in "dragon bones". It was he who, in 1918, discovered

2844-510: A subspecies of H. erectus s. l. (for example, the Arago material as " H. e. tautavelensis "). In 2018, Mirjana Roksandic and colleagues revised the hypodigm of H. heidelbergensis to include only the specimens with no Neanderthal-derived traits (namely Mauer, Mala Balanica , Ceprano, HaZore'a and Nadaouiyeh Aïn Askar ). There is no defined distinction between latest potential H. heidelbergensis material – specifically Steinheim and SH – and

3002-468: A taller trochlea of the ankle bone , making the ankle more flexible (specifically dorsiflexion and plantarflexion). On the left side of its face, an SH skull ( Skull 5 ) presents the oldest-known case of orbital cellulitis (eye infection which developed from an abscess in the mouth). This probably caused sepsis , killing the individual. A male SH pelvis (Pelvis 1), based on joint degeneration, may have lived for more than 45 years, making him one of

3160-661: A thing of the past" (1977: 139). The first paleoanthropological find made in Africa was the 1921 discovery of the Kabwe 1 skull at Kabwe (Broken Hill) , Zambia. Initially, this specimen was named Homo rhodesiensis ; however, today it is considered part of the species Homo heidelbergensis . In 1924 in a limestone quarry at Taung , Professor Raymond Dart discovered a remarkably well-preserved juvenile specimen (face and brain endocast), which he named Australopithecus africanus ( Australopithecus meaning "Southern Ape"). Although

3318-491: A timespan of about a million years, and such technological stagnation has typically been ascribed to comparatively limited cognitive abilities which significantly reduced innovative capacity, such as a deficit in cognitive fluidity, working memory , or a social system compatible with apprenticeship. Nonetheless, the Acheulian does seem to subtly change over time, and is typically split up into Early Acheulian and Late Acheulian,

3476-457: A unique species. Although most hominin fossils from Africa have been found in eastern and southern Africa, there are a few exceptions. One is Sahelanthropus tchadensis , discovered in the central African country of Chad in 2002. This find is important because it widens the assumed geographic range of early hominins. Homo heidelbergensis Homo heidelbergensis (also H. erectus heidelbergensis , H. sapiens heidelbergensis )

3634-399: A vital tool of research of the evolutionary kinship lines of related species and genera. The term paleoanthropology derives from Greek palaiós (παλαιός) "old, ancient", ánthrōpos (ἄνθρωπος) "man, human" and the suffix -logía (-λογία) "study of". Hominoids are a primate superfamily, the hominid family is currently considered to comprise both the great ape lineages and human lineages within

3792-523: A wealth of faunal and lithic materials, as well as hominin fossils. These included 5 more complete calvaria, 9 large cranial fragments, 6 facial fragments, 14 partial mandibles, 147 isolated teeth, and 11 postcranial elements—estimated to represent as least 40 individuals. Evidence of fire, marked by ash lenses and burned bones and stones, were apparently also present, although recent studies have challenged this view. Franz Weidenreich came to Beijing soon after Black’s untimely death in 1934, and took charge of

3950-480: Is an extinct species or subspecies of archaic human which existed during the Middle Pleistocene . It was subsumed as a subspecies of H. erectus in 1950 as H. e. heidelbergensis , but towards the end of the century, it was more widely classified as its own species. It is debated whether or not to constrain H. heidelbergensis to only Europe or to also include African and Asian specimens, and this

4108-682: Is broad, the parietal bone can be expanded, and the squamous part of temporal bone is high and arched, which could all be related to increasing brain size. The sphenoid bone features a spine extending downwards, and the articular tubercle on the underside of the skull can jut out prominently as the surface behind the jaw hinge is otherwise quite flat. In 2004, Rightmire estimated the brain volumes of ten Middle Pleistocene humans variously attributable to H. heidelbergensis —from Kabwe, Bodo, Ndutu, Dali, Jinniushan, Petralona, Steinheim, Arago, and two from SH. This set gives an average volume of about 1,206 cc, ranging from 1,100 to 1,390 cc. He also averaged

4266-440: Is broader, taller and thicker (expanded anteroposteriorly) than those of Neanderthals or modern humans, and retains an anteriorly located acetabulocristal buttress (which supports the iliac crests during hip abduction), a well defined supraacetabular groove (between the hip socket and the ilium), and a thin and rectangular superior pubic ramus (as opposed to the thick, stout one in modern humans). The foot of all archaic humans has

4424-807: Is evidence for the butchery of roe deer , horse and rhinoceros. The inhabitants of Terra Amata in France seem to have been mainly eating deer, but also elephants, boar, ibex, rhino and aurochs . African sites commonly yield bovine and horse bones. Though carcasses may have simply been scavenged, some Afro-European sites show specific targeting of a single species, which more likely indicates active hunting; for example: Olorgesailie , Kenya, which has yielded over 50 to 60 individual baboons ( Theropithecus oswaldi ); and Torralba and Ambrona in Spain which have an abundance of elephant bones (though also rhino and large hoofed mammals). The increase in meat subsistence could indicate

4582-470: Is further confounded by the type specimen ( Mauer 1 ) being a jawbone, because jawbones feature few diagnostic traits and are generally missing among Middle Pleistocene specimens. Thus, it is debated if some of these specimens could be split off into their own species or a subspecies of H. erectus . Because the classification is so disputed, the Middle Pleistocene is often called the "muddle in

4740-585: Is indicated by the production of smaller, thinner, and more symmetrical hand axes (though thicker, less refined ones were still produced). At the 500,000-year-old Boxgrove site in England—an exceptionally well-preserved site with abundance of tool remains—thinning may have been produced by striking the hand axe near-perpendicularly with a soft hammer , possible with the invention of prepared platforms for tool making. The Boxgrove knappers also left behind large lithic flakes leftover from making hand axes, possibly with

4898-584: Is justifiable. Mayr's lumping of H. heidelbergensis was first opposed by American anthropologist Francis Clark Howell in 1960. In 1974, British physical anthropologist Chris Stringer pointed out similarities between the Kabwe 1 and the Greek Petralona skulls to the skulls of modern humans ( H. sapiens or H. s. sapiens ) and Neanderthals ( H. neanderthalensis or H. s. neanderthalensis ). So, Stringer assigned them to Homo sapiens sensu lato ("in

5056-636: Is known to have consumed the largest megafauna species present in the region, the straight-tusked elephant (which has been found at numerous sites with cut marks and/or stone tools indicating butchery) and rhinoceroses belonging to the genus Stephanorhinus . At the Schöningen spear horizon in Germany, there is extensive evidence for the butchery of horses. At the Boxgrove site in England, there

5214-436: Is most clearly demonstrated in the exceptionally well-preserved SH assemblage. Based on skull robustness, it was assumed Middle Pleistocene humans featured a high degree of sexual dimorphism , but the SH humans demonstrate a modern humanlike level. The SH humans and other Middle Pleistocene Homo have a more basal pelvis and femur (more similar to earlier Homo than Neanderthals). The overall broad and elliptical pelvis

5372-605: Is not as universally accepted. After the 2010 identification of the genetic code of some unique archaic human species in Siberia, termed " Denisovans " pending diagnostic fossil finds, it is postulated that the Asian remains could represent that same species. Thus, Middle Pleistocene Asian specimens, such as Dali Man or the Indian Narmada Man , remain enigmatic. The paleontology institute at Heidelberg University , where

5530-655: Is obfuscated by a long gap in the human fossil record near the end of the Early Pleistocene . In 2016, Antonio Profico and colleagues suggested that 875,000-year-old skull materials from the Gombore II site of the Melka Kunture Formation, Ethiopia, represent a transitional morph between H. ergaster and H. heidelbergensis , and thus postulated that H. heidelbergensis originated in Africa instead of Europe. According to genetic analysis,

5688-419: Is suggested there were multiple lineages (or species) in this region and time period, but French palaeoanthropologist Jean-Jacques Hublin considers this an unjustified extrapolation as they may have simply been different but still interconnected populations of a single, highly variable species. In 2015, Marie Antoinette de Lumley suggested the less derived material can also be split off into their own species or

5846-635: Is supposed to represent the immediate ancestor of modern humans, but does not include the LCA of modern humans and Neanderthals. They suggested the confusing morphology of the Middle Pleistocene was caused by periodic H. bodoensis migration events into Europe following population collapses after glacial cycles, interbreeding with surviving indigenous populations. Their taxonomic recommendations were rejected by Stringer and others as they failed to explain how exactly their proposals would resolve anything, in addition to violating nomenclatural rules. H. heidelbergensis

6004-535: Is the 780,000-year-old Gesher Benot Ya'aqov , Israel. In Europe, evidence of constructed dwelling structures—classified as firm surface huts with solid foundations built in areas mostly sheltered from the weather—has been recorded since the Cromerian Interglacial , the earliest example a 700,000-year-old stone foundation from Přezletice , Czech Republic. This dwelling probably featured a vaulted roof made of thick branches or thin poles, supported by

6162-496: Is thought to have descended from African H. erectus — sometimes classified as Homo ergaster — during the first early expansions of hominins out of Africa beginning roughly 2 million years ago. Those that dispersed across Europe and stayed in Africa evolved into H. heidelbergensis or speciated into H. heidelbergensis in Europe and " H. rhodesiensis " in Africa, and those that dispersed across East Asia evolved into H. erectus s. s. The exact derivation from an ancestor species

6320-458: Is typically considered the last common ancestor (LCA). This would make H. heidelbergensis a member of a chronospecies . It is much debated if the name H. heidelbergensis can be extended to Middle Pleistocene humans across the Old World, or if it is better to restrict it to just Europe. In the latter case, Middle Pleistocene African remains can be split off into " H. rhodesiensis ". In

6478-511: Is unclear if this is because Neanderthals were less capable of exploiting natural resources, or because they lived in harsher environments. A peak at 3½ years of age may be correlated with weaning age. In Neanderthals this peak was at 4 years, and many modern hunter gatherers also wean at about 4 years of age. Middle Pleistocene communities in general seem to have eaten big game at a higher frequency than predecessors, with meat becoming an essential dietary component. In Europe, Homo heidelbergensis

6636-526: Is unclear if this is part of a long blade-making tradition, or if blade technology was lost and reinvented several times by multiple different human species. Despite apparent pushes into colder climates, evidence of fire is scarce in the archaeological record until 400 to 300 thousand years ago. Though it is possible fire remnants simply degraded, long and overall undisturbed occupation sequences such as at Arago or Gran Dolina conspicuously lack convincing evidence of fire usage. This pattern could possibly indicate

6794-689: The American Museum of Natural History , examined the Piltdown and Sheffield Park finds and declared that the jaw and skull belonged together "without question" and that the Sheffield Park fragments "were exactly those which we should have selected to confirm the comparison with the original type ." The Sheffield Park finds were taken as proof of the authenticity of the Piltdown Man; it may have been chance that brought an ape's jaw and

Of his antiquarian publications, most demonstrate evidence of plagiarism or at least naive referencing. Russell wrote: "Piltdown

The first prepared platforms in Africa come from the 450,000-year-old Fauresmith industry , transitional between the Early Stone Age ( Acheulian ) and the Middle Stone Age . With either method, knappers (tool makers) would have had to have produced some item indirectly related to creating

7268-457: The Sima de los Huesos (SH) hominins were buried by people rather than being the victims of some catastrophic event such as a cave-in, because young children and infants are absent which would be unexpected if this were a single and complete family unit. The SH humans are conspicuously associated with only a single stone tool, a carefully crafted hand axe made of high-quality quartzite (rarely used in

7426-459: The Taung Child and Peking Man were made. R. W. Ehrich and G. M. Henderson note, "To those who are not completely disillusioned by the work of their predecessors, the disqualification of the Piltdown skull changes little in the broad evolutionary pattern. The validity of the specimen has always been questioned". Eventually, during the 1940s and 1950s, more advanced dating technologies, such as

7584-478: The eolith theory, which Morris strongly supported. Adrian Lister of the UK's Natural History Museum has said that "some people have suggested" that there may also have been a second 'fraudster' seeking to use outrageous fraud in the hope of anonymously exposing the original frauds. This was a theory first proposed by Miles Russell . He has explained that the piece nicknamed the 'cricket bat' (a fossilised elephant bone)

7742-470: The fluorine absorption test , proved scientifically that this skull was actually a fraud. The Piltdown Man fraud significantly affected early research on human evolution. Notably, it led scientists down a blind alley in the belief that the human brain expanded in size before the jaw adapted to new types of food. Discoveries of Australopithecine fossils such as the Taung child found by Raymond Dart during

7900-486: The hominoid superfamily. The " Homininae " comprise both the human lineages and the African ape lineages. The term "African apes" refers only to chimpanzees and gorillas . The terminology of the immediate biological family is currently in flux. The term "hominin" refers to any genus in the human tribe (Hominini), of which Homo sapiens (modern humans) is the only living specimen. In 1758 Carl Linnaeus introduced

He split this off as a new species primarily because of the mandible's archaicness—in particular its enormous size—and it was the then-oldest human jaw in the European fossil record at 640,000 years old. The mandible is well preserved, missing only the left premolars , part of the first left molar , the tip of the left coronoid process (at

8216-436: The 'Ashburnham Dial', and the 'Piltdown Palaeolith'. Nevertheless, the 'cricket bat' was accepted at the time, even though it aroused the suspicions of some and ultimately helped lead to the eventual recognition of the fraud decades later. In 2016, the results of an eight-year review of the forgery were released, identifying Dawson's modus operandi . Multiple specimens demonstrated the same consistent preparation: application of

8374-400: The 1920s in South Africa were ignored because of the support for Piltdown Man as "the missing link," and the reconstruction of human evolution was confused for decades. The examination and debate over Piltdown Man caused a vast expenditure of time and effort on the fossil, with an estimated 250+ papers written on the topic. The book Scientology: A History of Man by L. Ron Hubbard features

8532-409: The 1930s, paleontologist Robert Broom discovered and described a new species at Kromdraai , South Africa. Although similar in some ways to Dart's Australopithecus africanus , Broom's specimen had much larger cheek teeth. Because of this difference, Broom named his specimen Paranthropus robustus , using a new genus name. In doing so, he established the practice of grouping gracile australopiths in

8690-419: The 19th century with the discovery of " Neanderthal man" (the eponymous skeleton was found in 1856, but there had been finds elsewhere since 1830), and with evidence of so-called cave men . The idea that humans are similar to certain great apes had been obvious to people for some time, but the idea of the biological evolution of species in general was not legitimized until after Charles Darwin published On

8848-467: The American zoologist Gerrit Smith Miller Jr. concluded that Piltdown's jaw came from a fossil ape. In 1923, Franz Weidenreich examined the remains and correctly reported that they consisted of a modern human cranium and an orangutan jaw with filed-down teeth. In 1915, Dawson claimed to have found three fragments of a second skull (Piltdown II) at a new site about two miles (3.2 km) away from

9006-607: The Cenozoic Laboratory opened up new avenues for the study of paleogeology and paleontology in China. The Laboratory was the precursor of the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Science, which took its modern form after 1949. The first of the major project finds are attributed to the young Swedish paleontologist, Anders Birger Bohlin , then serving as

9164-482: The LCA of modern humans and Neanderthal split into a modern human line, and a Neanderthal/Denisovan line, and the latter later split into Neanderthal and Denisovans. According to nuclear DNA analysis, the 430,000-year-old SH humans are more closely related to Neanderthals than Denisovans (and that the Neanderthal/Denisovan, and thus the modern human/Neanderthal split, had already occurred), suggesting

9322-474: The LCA rather than being the LCA itself (that is, H. heidelbergensis did not derive from H. antecessor ). Human dispersal beyond 45°N seems to have been quite limited during the Lower Palaeolithic , with evidence of short-lived dispersals northward beginning after a million years ago. Beginning 700,000 years ago, more permanent populations seem to have persisted across the line coinciding with

9480-473: The Lower Paleolithic. The appearance of repeated fire usage—earliest in Europe from Beeches Pit, England, and Schöningen, Germany—roughly coincides with hafting technology (attaching stone points to spears) best exemplified by the Schöningen spears . These nine wooden spears and spear fragments—in addition to a lance, and a double-pointed stick—date to 300,000 years ago and were preserved along

9638-522: The Mauer mandible are missing in the SH humans. In palaeoanthropology, the Middle Pleistocene is often termed the "muddle in the middle" because the species-level classification of archaic human remains from this time period has been heavily debated. The ancestors of modern humans ( Homo sapiens or H. s. sapiens ) and Neanderthals ( H. neanderthalensis or H. s. neanderthalensis ) diverged during this time period, and, by convention, H. heidelbergensis

9796-490: The Mauer mandible has been kept since 1908, changed the label from H. e. heidelbergensis to H. heidelbergensis in 2015. In 1976 at Sima de los Huesos (SH) in the Sierra de Atapuerca , Spain, Spanish paleontologists Emiliano Aguirre , José María Basabe and Trinidad Torres began to excavate archaic human remains. Their investigation of the site was prompted by the finding of several bear remains ( Ursus deningeri ) since

9954-613: The Middle Pleistocene Old World. If this is the case, then most all populations of any archaic human species would have generally averaged to 165–170 cm (5 ft 5 in – 5 ft 7 in) in height. Early modern humans were notably taller, with the Skhul and Qafzeh remains averaging 185.1 cm (6 ft 1 in) for males and 169.8 cm (5 ft 7 in) for females, an average of 177.5 cm (5 ft 10 in), possibly to increase

10112-634: The Natural History Museum in London held an exhibition to mark the 50th anniversary of the exposure of the fraud. The Piltdown case is an example of how race, nationalism, and gender influenced scientific and public opinion. Newspapers explained the seemingly primitive and contradictory features of the skull and jaw by attempting to demonstrate an analogy with non-white races, presumed at the time to be more primitive and less developed than white Europeans. The influence of nationalism resulted in

10270-490: The Origin of Species in 1859. Though Darwin's first book on evolution did not address the specific question of human evolution—"light will be thrown on the origin of man and his history," was all Darwin wrote on the subject—the implications of evolutionary theory were clear to contemporary readers. Debates between Thomas Huxley and Richard Owen focused on the idea of human evolution. Huxley convincingly illustrated many of

10428-415: The Piltdown Man as a phase of biological history capable of leaving a person with subconscious memories of traumatic incidents that can only be resolved by use of Scientology technology. Recovered "memories" of this phase are prompted by one's obsession with biting, hiding the teeth or mouth, and early familial issues. Nominally, this appears to be related to the large jaw of the Piltdown Man specimen. The book

10586-612: The Piltdown fragments was strongly challenged by some researchers. At the Royal College of Surgeons , copies of the same fragments used by the British Museum in their reconstruction were used to produce an entirely different model, one that in brain size and other features resembled a modern human. This reconstruction, by Arthur Keith , was called Homo piltdownensis in reflection of its more human appearance. Woodward's reconstruction included ape-like canine teeth , which

10744-535: The Taung child was a bipedal human ancestor, a transitional form between ape and human. However, Dart's conclusions were largely ignored for decades, as the prevailing view of the time was that a large brain evolved before bipedality. It took the discovery of additional australopith fossils in Africa that resembled his specimen, and the rejection of the Piltdown Man hoax , for Dart's claims to be taken seriously. In

Enamel hypoplasia on the teeth is used to determine bouts of nutritional stress. At a rate of 40% for the SH humans, this is significantly higher than exhibited in the earlier South African hominin Paranthropus robustus at Swartkrans (30.6%) or Sterkfontein (12.1%). Nonetheless, Neanderthals suffered even higher rates and more intense bouts of hypoplasia, but it

11060-600: The anomalous finds originated, and resided in the Wealden area from the date of the earliest finds (although others suggest that he was "without doubt innocent in this matter"). Hinton left a trunk in storage at the Natural History Museum in London that in 1970 was found to contain animal bones and teeth carved and stained in a manner similar to the carving and staining on the Piltdown finds. Phillip Tobias implicated Arthur Keith in helping Dawson by detailing

11218-486: The appearance of hafting technology to create spears. H. heidelbergensis may have been able to carry out coordinated hunting strategies, and consequently they seem to have had a higher dependence on meat. The first fossil, Mauer 1 (a jawbone), was discovered by a worker in Mauer , southeast of Heidelberg , Germany, in 1907. It was formally described the next year by German anthropologist Otto Schoetensack , who made it

11376-432: The assemblage remained the subject of considerable controversy until it was conclusively exposed in 1953 as a forgery. It was found to have consisted of the altered mandible and some teeth of an orangutan deliberately combined with the cranium of a fully developed, though small-brained, modern human . The Piltdown hoax is prominent for two reasons: the attention it generated around the subject of human evolution , and

11534-579: The back of the jaw), a developed planum triangulare (near the jaw hinge), and a mylohyoid line originating at the level of the third molar. Trends in body size through the Middle Pleistocene are obscured due to a general lack of limb bones and non-skull (post-cranial) remains. Based on the lengths of various long bones , the SH humans averaged roughly 169.5 cm (5 ft 7 in) for males and 157.7 cm (5 ft 2 in) for females, with maximums of respectively 177 cm (5 ft 10 in) and 160 cm (5 ft 3 in). The height of

11692-492: The belief that it was a fossilised coconut . Revisiting the site on several occasions, Dawson found further fragments of the skull and took them to Arthur Smith Woodward , keeper of the geological department at the British Museum . Greatly interested by the finds, Woodward accompanied Dawson to the site. Though the two worked together between June and September 1912, Dawson alone recovered more skull fragments and half of

11850-731: The brain volumes of 30 H. erectus / ergaster specimens, spanning nearly 1.5 million years from across East Asia and Africa, as 973 cc, and thus concluded a significant jump in brain size, though conceded brain size was extremely variable ranging from 727 to 1,231 cc depending on the time period, geographic region, and even between individuals within the same population (the last one probably due to notable sexual dimorphism with males much bigger than females). In comparison, for modern humans, brain size averages 1,270 cc for males and 1,130 cc for females; and for Neanderthals 1,600 cc for males and 1,300 cc for females. In 2009, palaeontologists Aurélien Mounier, François Marchal and Silvana Condemi published

12008-455: The brain was small (410 cm ), its shape was rounded, unlike the brain shape of chimpanzees and gorillas, and more like the shape seen in modern humans. In addition, the specimen exhibited short canine teeth , and the anterior placement of the foramen magnum was more like the placement seen in modern humans than the placement seen in chimpanzees and gorillas, suggesting that this species was bipedal . All of these traits convinced Dart that

12166-494: The broad sense"), as ancestral to modern humans and Neanderthals. In 1979, Stringer and Finnish anthropologist Björn Kurtén found that the Kabwe and Petralona skulls are associated with the Cromerian industry like the Mauer mandible, and thus postulated these three populations might be allied with each other. Though these fossils are poorly preserved and do not provide many comparable possible diagnostic traits (and likewise it

12324-425: The cheek teeth, a horizontal retromolar space (a gap behind the molars), a gutter between the molars and the ramus (which juts up to connect with the skull), an overall long jaw, a deep fossa (a depression) for the masseter muscle (which closes the jaw), a small gonial angle (the angle between the body of the mandible and the ramus), an extensive planum alveolare (the distance from the frontmost tooth socket to

12482-494: The combination of a human-like cranium with an ape-like jaw tended to support the notion then prevailing in England that human evolution began with the brain. The find was considered legitimate by Otto Schoetensack who had discovered the Heidelberg fossils just a few years earlier; he described it as being the best evidence for an ape-like ancestor of modern humans. But almost from the outset, Woodward's reconstruction of

12640-442: The desired product (hierarchical organisation), which could represent a major cognitive development. Experiments with modern humans have shown that platform preparation cannot be learned through purely observational learning, unlike earlier techniques, and could be indicative of well developed teaching methods as well as self-regulated learning . At Boxgrove, the knappers used not only stone but also bone and antler to make hammers, and

12798-507: The development of group hunting strategies in the Middle Pleistocene. For instance, at Torralba and Ambrona, the animals may have been run into swamplands before being killed, entailing encircling and driving by a large group of hunters in a coordinated and organised attack. Exploitation of aquatic environments is generally quite lacking, despite some sites being in close proximity to the ocean, lakes or rivers. Plants were probably also frequently consumed, including seasonally available ones, but

12956-461: The differing interpretations of the find: whilst the majority of British scientists accepted the discovery as "the earliest Englishman", European and American scientists were considerably more sceptical, and several suggested at the time that the skull and jaw were from two different creatures and had been accidentally mixed up. Although Woodward suggested that the specimen discovered might be female, most scientists and journalists referred to Piltdown as

13114-399: The earliest Neanderthal specimens— Biache , France; Ehringsdorf , Germany; or Saccopastore , Italy. The use of the Mauer mandible, an isolated jawbone, as the type specimen for the species has been problematic as it does not present many diagnostic features, and in addition it is missing from several Middle Pleistocene specimens. Anthropologist William Straus said on this topic that, "While

13272-509: The earliest humans would be found in Eurasia , and the British in particular wanted a "first Briton" to set against fossil hominids found elsewhere in Europe. The identity of the Piltdown forger remains unknown, but suspects have included Dawson, Pierre Teilhard de Chardin , Arthur Keith , Martin A. C. Hinton , Horace de Vere Cole and Arthur Conan Doyle . The focus on Charles Dawson as

13430-640: The early 20th century by amateur cavers (which consequently destroyed some of the human remains in that section). By 1990, about 600 human remains were reported, and by 2004 the number had increased to roughly 4,000. These represent at least 28 individuals, of which possibly only one is a child, and the rest teenagers and young adults. The fossil assemblage is exceptionally complete, with whole corpses buried rapidly, and all bodily elements represented. In 1997, Spanish palaeoanthropologist Juan Luis Arsuaga assigned these to H. heidelbergensis , but in 2014, he retracted this, stating that Neanderthal-like features present in

13588-469: The energy-efficiency of long-distance travel with longer legs. A conspicuously massive proximal (upper half) femur was recovered from Berg Aukas Mine, Namibia, about 20 km (12 mi) east of Grootfontein . It was originally estimated to have been from a male as much as 93 kg (205 lb) in life, but its exorbitant size is now proposed to be the consequence of an extraordinarily vigorous early-life activity level while an otherwise ordinary person

13746-459: The evolution of Homo heidelbergensis . In comparison to Early Pleistocene H. erectus / ergaster , Middle Pleistocene humans have a much more modern human-like face. The nasal opening is set completely vertically in the skull, and the anterior nasal sill can be crested or sometimes a prominent spine. The incisive canals (on the roof of the mouth ) open near the teeth, and are orientated like those of more recent human species. The frontal bone

13904-684: The extent of their exploitation is unclear as they do not fossilise as well as animal bones. At the Schöningen site in Germany, it is estimated that over 200 plant species in the vicinity were either edible raw or when cooked, though relatively few have actually been found at the site itself. Upper Palaeolithic modern humans are well known for having etched engravings seemingly with symbolic value. As of 2018, only 27 Middle and Lower Palaeolithic objects have been postulated to have symbolic etching, out of which some have been refuted as having been caused by natural or otherwise non-symbolic phenomena (such as

14062-434: The false fossils to Dawson, but ruled out several other suspects, including Teilhard de Chardin and Doyle, based on the skill and knowledge demonstrated by the forgeries, which closely reflected ideas fashionable in biology at the time. On the other hand, Stephen Jay Gould judged that Pierre Teilhard de Chardin conspired with Dawson in the Piltdown forgery. Teilhard de Chardin had travelled to regions of Africa where one of

14220-654: The famous Laetoli footprints in Tanzania, which demonstrated the antiquity of bipedality in the human lineage. In 1985, Richard Leakey and Alan Walker discovered a specimen they called the Black Skull , found near Lake Turkana. This specimen was assigned to another species, Paranthropus aethiopicus . In 1994, a team led by Meave Leakey announced a new species, Australopithecus anamensis , based on specimens found near Lake Turkana. Numerous other researchers have made important discoveries in eastern Africa. Possibly

14378-415: The field advisor at Zhoukoudian . He recovered a left lower molar that Black (1927) identified as unmistakably human (it compared favorably to the previous find made by Zdansky), and subsequently coined it Sinanthropus pekinensis . The news was at first met with skepticism, and many scholars had reservations that a single tooth was sufficient to justify the naming of a new type of early hominin. Yet within

14536-450: The find to end any dispute over his reconstruction of the skull. However, Keith attacked the find. Keith pointed out that human molars are the result of side to side movement when chewing. The canine in the Piltdown jaw was impossible as it prevented side to side movement. To explain the wear on the molar teeth, the canine could not have been any higher than the molars. Grafton Elliot Smith , a fellow anthropologist, sided with Woodward, and at

14694-499: The finds, and Dawson was known to be personally ambitious. He wanted professional recognition. He wanted to be a member of the Royal Society and he was after an MBE [sic]. He wanted people to stop seeing him as an amateur". In 1912, the majority of the scientific community believed the Piltdown Man was the " missing link " between apes and humans. However, over time the Piltdown Man lost its validity, as other discoveries such as

14852-414: The first differential diagnosis of H. heidelbergensis using the Mauer mandible, as well as material from Tighennif, Algeria; SH, Spain; Arago, France; and Montmaurin , France. They listed the diagnostic traits as: a reduced chin, a notch in the submental space (near the throat), parallel upper and lower boundaries of the mandible in side-view, several mental foramina (small holes for blood vessels) near

15010-577: The fossil KNM-ER 1470 near Lake Turkana in Kenya. KNM-ER 1470 has been interpreted as either a distinct species, Homo rudolfensis , or alternatively as evidence of sexual dimorphism in Homo habilis . In 1967, Richard Leakey reported the earliest definitive examples of anatomically modern Homo sapiens from the site of Omo Kibish in Ethiopia, known as the Omo remains . In the late 1970s, Mary Leakey excavated

15168-489: The fossil hominin teeth delighted the scientific community in Beijing, and plans for developing a larger, more systematic project at Zhoukoudian were soon formulated. At the epicenter of excitement was Davidson Black , a Canadian-born anatomist working at Peking Union Medical College . Black shared Andersson’s interest, as well as his view that central Asia was a promising home for early humankind. In late 1926, Black submitted

15326-507: The fossil skull of Piltdown Man, 1912–1913, The discovery was described by Mr Charles Dawson and Sir Arthur Smith Woodward, Quarterly Journal of the Geological Society , 1913–15. From the outset, some scientists expressed scepticism about the Piltdown find (see above). Gerrit Smith Miller Jr. , for example, observed in 1915 that "deliberate malice could hardly have been more successful than the hazards of deposition in so breaking

15484-470: The fossilisation or excavation processes). The Lower Palaeolithic ones are: a 400,000 to 350,000 years old bone from Bilzingsleben , Germany; three 380,000-year-old pebbles from Terra Amata; a 250,000-year-old pebble from Markkleeberg , Germany; 18 roughly 200,000-year-old pebbles from Lazaret (near Terra Amata); a roughly 200,000-year-old lithic from Grotte de l'Observatoire , Monaco and a 200- to 130-thousand-year-old pebble from Baume Bonne , France. In

15642-494: The fossils as to give free scope to individual judgment in fitting the parts together". In the decades prior to its exposure as a forgery in 1953, scientists increasingly regarded Piltdown as an enigmatic aberration, inconsistent with the path of hominid evolution as demonstrated by fossils found elsewhere. In November 1953, Time magazine published evidence, gathered variously by Kenneth Page Oakley , Sir Wilfrid Edward Le Gros Clark and Joseph Weiner , proving that Piltdown Man

15800-463: The fossils could be confidently associated with the Acheulian artefacts from the sites, and suggested that—as an alternative to archaic human activity—apparent size-selection could have been caused by either natural geological processes or 19th-century collectors favouring this specific form. Early modern humans and late Neanderthals (the latter especially after 60,000 years ago) made wide use of red ochre for presumably symbolic purposes as it produces

15958-450: The genus Australopithecus and robust australopiths in the genus Paranthropus . During the 1960s, the robust variety was commonly moved into Australopithecus . A more recent consensus has been to return to the original classification of Paranthropus as a separate genus. The second half of the twentieth century saw a significant increase in the number of paleoanthropological finds made in Africa. Many of these finds were associated with

16116-451: The history of the investigation of the hoax, dismissing other theories, and listing inconsistencies in Keith's statements and actions. Other investigations suggest that the hoax involved accomplices rather than a single forger. Richard Milner , an American historian of science, argued that Arthur Conan Doyle may have been the perpetrator of the Piltdown Man hoax. Milner noted that Doyle had

16274-470: The hoax was seen as being too elaborate for him to have devised. However, the DNA evidence showed that a supposedly ancient tooth Dawson had "discovered" in 1915 (at a different site) came from the same jaw as that of the Piltdown Man, suggesting that he had planted them both. That tooth, too, was later proven to have been planted as part of a hoax. Chris Stringer, an anthropologist from the Natural History Museum,

16432-406: The idea that Doyle would be involved in such a hoax. However, more recent research suggests that Doyle was not involved. In 2016, researchers at the Natural History Museum and Liverpool John Moores University analyzed DNA evidence showing that responsibility for the hoax lay with Dawson, who had originally "found" the remains. Dawson had initially not been considered the likely perpetrator, because

16590-527: The idea that human beings could have evolved their apparently boundless mental capacities and moral sensibilities through natural selection . Prior to the general acceptance of Africa as the root of genus Homo , 19th-century naturalists sought the origin of humans in Asia. So-called "dragon bones" (fossil bones and teeth) from Chinese apothecary shops were known, but it was not until the early 20th century that German paleontologist, Max Schlosser , first described

16748-471: The intention of recycling them into other tools later. Late Acheulian sites elsewhere pre-prepared lithic cores ("Large Flake Blanks", LFB) in a variety of ways before shaping them into tools, making prepared platforms unnecessary. LFB Acheulian spreads out of Africa into West and South Asia before a million years ago and is present in Southern Europe after 600,000 years ago, but northern Europe (and

16906-460: The invention of ignition technology or improved fire maintenance techniques at this time, and that fire was not an integral part of people's lives before then in Europe. In Africa, on the other hand, humans may have been able to frequently scavenge fire as early as 1.6 million years ago from natural wildfires, which occur much more often in Africa, thus possibly (more or less) regularly using fire. The oldest established continuous fire site beyond Africa

17064-462: The jaw hinge), and fragments of the mid-section as the jaw was found in two pieces and had to be glued together. It may have belonged to a young adult based on slight wearing on the 3rd molar. In 1921, the skull Kabwe 1 was discovered by Swiss miner Tom Zwiglaar in Kabwe , Zambia (at the time Broken Hill, Northern Rhodesia ), and was assigned to a new species, " H. rhodesiensis ", by English palaeontologist Arthur Smith Woodward . These were two of

17222-522: The latter becoming especially popular after 600 to 500 thousand years ago. Late Acheulian technology never crossed over east of the Movius Line into East Asia, which is generally believed to be due to either some major deficit in cultural transmission (namely smaller population size in the East) or simply preservation bias as far fewer stone tool assemblages are found east of the line. The transition

17380-910: The latter view, " H. rhodesiensis " can either be seen as the direct ancestor of modern humans, or of " H. helmei " which evolved into modern humans. Regarding the Middle Pleistocene European remains, some are more firmly placed on the Neanderthal line (namely SH , Pontnewydd , Steinheim , and Swanscombe ), whereas others seem to have few uniquely Neanderthal features ( Tautavel in France, Ceprano in Italy, Vértesszőlős in Hungary, Bilzingsleben in Germany, Mala Balanica in Serbia, and Aroeira in Portugal). Because of this, it

17538-499: The length of time, 41 years, that elapsed from its alleged initial discovery to its definitive exposure as a composite forgery. At a meeting of the Geological Society of London on 18 December 1912, Charles Dawson claimed that a workman at the Piltdown gravel pit had given him a fragment of the skull four years earlier. According to Dawson, workmen at the site discovered the skull shortly before his visit and broke it up in

17696-401: The lower jaw. The skull unearthed in 1908 was the only find discovered in situ , with most of the other pieces found in the gravel pit's spoil heaps. French Jesuit paleontologist and geologist Pierre Teilhard de Chardin participated in the uncovering of the Piltdown skull with Woodward. At the same meeting, Woodward announced that a reconstruction of the fragments indicated that the skull

17854-469: The main forger is supported by the accumulation of evidence regarding other archaeological hoaxes he perpetrated in the decade or two before the Piltdown discovery. The archaeologist Miles Russell of Bournemouth University analysed Dawson's antiquarian collection, and determined that at least 38 of his specimens were fakes. Among these were the teeth of a multituberculate mammal, Plagiaulax dawsoni , "found" in 1891 (and whose teeth had been filed down in

18012-560: The many putative species of Middle Pleistocene Homo which were described throughout the first half of the 20th century. In the 1950s, Ernst Mayr had entered the field of anthropology, and, surveying a "bewildering diversity of names", decided to define only three species of Homo : " H. transvaalensis " (the australopithecines ), H. erectus (including the Mauer mandible, and various putative African and Asian taxa) and Homo sapiens (including anything younger than H. erectus , such as modern humans and Neanderthals ). Mayr defined them as

18170-585: The mid-19th century, French archaeologist Jacques Boucher de Crèvecœur de Perthes began excavation at St. Acheul, Amiens , France, (the area where the Acheulian was defined), and, in addition to hand axes, reported perforated sponge fossils ( Porosphaera globularis ) which he considered to have been decorative beads. This claim was completely ignored. In 1894, English archaeologist Worthington George Smith discovered 200 similar perforated fossils in Bedfordshire , England, and also speculated that their function

18328-438: The middle". H. heidelbergensis is regarded as a chronospecies , evolving from an African form of H. erectus (sometimes called H. ergaster ). By convention, H. heidelbergensis is placed as the most recent common ancestor between modern humans ( H. sapiens or H. s. sapiens ) and Neanderthals ( H. neanderthalensis or H. s. neanderthalensis ). Many specimens assigned to H. heidelbergensis likely existed well after

18486-402: The modern human/Neanderthal LCA had existed long before many European specimens typically assigned to H. heidelbergensis did, such as the Arago and Petralona materials. In 1997, Spanish archaeologist José María Bermúdez de Castro , Arsuaga, and colleagues described the roughly million-year-old H. antecessor from Gran Dolina , Sierra de Atapuerca, and suggested supplanting this species in

18644-412: The modern human/Neanderthal split. In the Middle Pleistocene, brain size averaged about 1,200 cubic centimetres (cc), comparable to modern humans. Height in the Middle Pleistocene can only be estimated based upon remains from three localities: Sima de los Huesos , Spain, 169.5 cm (5 ft 7 in) for males and 157.7 cm (5 ft 2 in) for females; 165 cm (5 ft 5 in) for

18802-439: The more closed-off end to fully open the hole. He also found wear facets which he speculated were begotten from clacking against other beads when they were strung together and worn as a necklace. In 2009, Solange Rigaud, Francisco d'Errico and colleagues noticed that the modified areas are lighter in colour than the unmodifed, suggesting they were inflicted much more recently such as during excavation. They were also unconvinced that

18960-626: The most famous is the Lucy skeleton , discovered in 1973 by Donald Johanson and Maurice Taieb in Ethiopia's Afar Triangle at the site of Hadar . On the basis of this skeleton and subsequent discoveries, the researchers came up with a new species, Australopithecus afarensis . In 1975, Colin Groves and Vratislav Mazák announced a new species of human they called Homo ergaster . Homo ergaster specimens have been found at numerous sites in eastern and southern Africa. In 1994, Tim D. White announced

19118-454: The name Homo sapiens as a species name in the 10th edition of his work Systema Naturae although without a scientific description of the species-specific characteristics. Since the great apes were considered the closest relatives of human beings, based on morphological similarity, in the 19th century, it was speculated that the closest living relatives to humans were chimpanzees (genus Pan ) and gorilla (genus Gorilla ), and based on

19276-614: The name rhodesiensis honours English diamond magnate Cecil Rhodes who disenfranchised the black population in southern Africa. They classified all European H. heidelbergensis as H. neanderthalensis , and synonymised H. rhodesiensis with a new species they named " H. bodoensis " which includes all African specimens, and potentially some from the Levant and the Balkans which have no Neanderthal-derived traits (namely Ceprano, Mala Balanica, HaZore'a and Nadaouiyeh Aïn Askar). H. bodoensis

19434-697: The natural range of these creatures, it was surmised that humans shared a common ancestor with African apes and that fossils of these ancestors would ultimately be found in Africa. The science arguably began in the late 19th century when important discoveries occurred that led to the study of human evolution . The discovery of the Neanderthal in Germany, Thomas Huxley 's Evidence as to Man's Place in Nature , and Charles Darwin 's The Descent of Man were both important to early paleoanthropological research. The modern field of paleoanthropology began in

19592-533: The next Royal Society meeting claimed that Keith's opposition was motivated entirely by ambition. Keith later recalled, "Such was the end of our long friendship." As early as 1913, David Waterston of King's College London published in Nature his conclusion that the sample consisted of an ape mandible and human skull. Likewise, French paleontologist Marcellin Boule concluded the same in 1915. A third opinion from

19750-539: The oldest examples of this demographic in the human fossil record. The frequency of 45-plus individuals gradually increases with time, but has overall remained quite low throughout the Palaeolithic. He similarly had the age-related maladies lumbar kyphosis (excessive curving of the lumbar vertebrae of the lower back), L5–S1 spondylolisthesis (misalignment of the last lumbar vertebra with the first sacral vertebra ), and Baastrup disease on L4 and 5 (enlargement of

19908-532: The original finds. Woodward attempted several times to elicit the location from Dawson, but was unsuccessful. So far as is known, the site was never identified and the finds appear largely undocumented. Woodward did not present the new finds to the Society until five months after Dawson's death in August 1916 and deliberately implied that he knew where they had been found. In 1921, Henry Fairfield Osborn , President of

20066-491: The paleoanthropological spotlight shifted westward to East Africa. Although China re-opened its doors to the West in the late 1970s, national policy calling for self-reliance, coupled with a widened language barrier, thwarted all the possibilities of renewed scientific relationships. Indeed, Harvard anthropologist K. C. Chang noted, "international collaboration (in developing nations very often a disguise for Western domination) became

20224-413: The place of H. heidelbergensis for the LCA between modern humans and Neanderthals, with H. heidelbergensis descending from it and being a strictly European species ancestral to only Neanderthals. They later recanted. In 2020, Dutch molecular palaeoanthropologist Frido Welker and colleagues analysed ancient proteins collected from an H. antecessor tooth found that it was a member of a sister lineage to

20382-536: The region), and so Carbonell and Mosquera postulated this was purposefully and symbolically placed with the bodies as some kind of grave good. Supposed evidence of symbolic graves would not surface for another 300,000 years. The Lower Palaeolithic (Early Stone Age) comprises the Oldowan which was replaced by the Acheulian , which is characterised by the production of mostly symmetrical hand axes . The Acheulian has

20540-655: The same way that the teeth of Piltdown Man were to be some 20 years later); the so-called "shadow figures" on the walls of Hastings Castle ; a unique hafted stone axe; the Bexhill boat (a hybrid seafaring vessel); the Pevensey bricks (allegedly the latest datable "finds" from Roman Britain); the contents of the Lavant Caves (a fraudulent "flint mine"); the Beauport Park "Roman" statuette (a hybrid iron object);

20698-423: The similarities and differences between humans and apes in his 1863 book Evidence as to Man's Place in Nature . By the time Darwin published his own book on the subject, Descent of Man , it was already a well-known interpretation of his theory—and the interpretation which made the theory highly controversial. Even many of Darwin's original supporters (such as Alfred Russel Wallace and Charles Lyell ) balked at

20856-459: The site of Dikika in the Afar region of Ethiopia. This find is particularly important because the fossil included a preserved hyoid bone , something rarely found in other paleoanthropological fossils but important for understanding the evolution of speech capacities. Two new species from southern Africa have been discovered and described in recent years. In 2008, a team led by Lee Berger announced

21014-492: The site, which they connected to the same individual. These finds included a jawbone , more skull fragments, a set of teeth, and primitive tools. Woodward reconstructed the skull fragments and hypothesised that they belonged to a human ancestor from 500,000 years ago. The discovery was announced at a Geological Society meeting and was given the Latin name Eoanthropus dawsoni ("Dawson's dawn-man"). The questionable significance of

21172-698: The sites around Zhoukoudian , a village about 50 kilometers southwest of Beijing. However, because of the sparse nature of the initial finds, the site was abandoned. Work did not resume until 1921, when the Austrian paleontologist, Otto Zdansky , fresh with his doctoral degree from Vienna, came to Beijing to work for Andersson. Zdansky conducted short-term excavations at Locality 1 in 1921 and 1923, and recovered only two teeth of significance (one premolar and one molar) that he subsequently described, cautiously, as "? Homo sp. " (Zdansky, 1927). With that done, Zdansky returned to Austria and suspended all fieldwork. News of

21330-448: The skull is the creation of God, the jaw is the work of the devil." If the Mauer mandible is actually a member of a different species than the Kabwe skull and most other Afro-European Middle Pleistocene archaic humans, then " H. rhodesiensis " would take priority as the name of the LCA. In 2021, Canadian anthropologist Mirjana Roksandic and colleagues recommended the complete dissolution of H. heidelbergensis and " H. rhodesiensis ", as

21488-406: The species Orrorin tugenensis , based on fossils they found in Kenya. In 2004, Yohannes Haile-Selassie announced that some specimens previously labeled as Ardipithecus ramidus made up a different species, Ardipithecus kadabba . In 2015, Haile-Selassie announced another new species, Australopithecus deyiremeda , though some scholars are skeptical that the associated fossils truly represent

21646-466: The spinous processes). These would have produced lower back pain, significantly limiting movement, and may be evidence of group care. An adolescent SH skull (Cranium 14) was diagnosed with lambdoid single suture craniosynostosis (immature closing of the left lambdoid suture , leading to skull deformities as development continued). This is a rare condition, occurring in less than 6 out of every 200,000 individuals in modern humans. The individual died around

21804-558: The spread of hand axe technology across Europe, possibly associated with the dispersal of H. heidelbergensis and behavioural shifts to cope with the cold climate. Such occupation becomes much more frequent after 500,000 years ago. In 2023, a genomics analysis of over 3,000 living individuals indicated that Homo sapiens' ancestral population was reduced to less than 1,300 individuals between 800,000 and 900,000 years ago. Prof Giorgio Manzi, an anthropologist at Sapienza University of Rome, suggested that this bottleneck could have triggered

21962-428: The stain, packing of crevices with local gravel, and fixation of teeth and gravel with dentist's putty. Analysis of shape and trace DNA showed that teeth from both sites belonged to the same orangutan. The consistent method and common source indicated the work of one person on all the specimens, and Dawson was the only one associated with Piltdown II. The authors did not rule out the possibility that someone else provided

22120-525: The strict sense", in this case, specimens from East Asia). Consequently, Afro-European remains from 600 to 300 thousand years ago—most notably from Kabwe, Petralona, Bodo and Arago —are often classified as H. heidelbergensis . In 2010, American physical anthropologist Jeffrey H. Schwartz and Tattersall suggested classifying all Middle Pleistocene European as well as Asian specimens—namely from Dali and Jinniushan in China—as H. heidelbergensis . This model

22278-649: The study of the hominin specimens. Following the loss of the Peking Man materials in late 1941, scientific endeavors at Zhoukoudian slowed, primarily because of lack of funding. Frantic search for the missing fossils took place, and continued well into the 1950s. After the establishment of the People’s Republic of China in 1949, excavations resumed at Zhoukoudian. But with political instability and social unrest brewing in China, beginning in 1966, and major discoveries at Olduvai Gorge and East Turkana ( Koobi Fora ),

22436-464: The teeth to a shape more suited to a human diet. The Piltdown Man hoax succeeded so well because, at the time of its discovery, the scientific establishment believed that the large modern brain preceded the modern omnivorous diet, and the forgery provided exactly that evidence. Stephen Jay Gould argued that nationalism and cultural prejudice played a role in the ready acceptance of Piltdown Man as genuine, because it satisfied European expectations that

22594-594: The use of such a wide range of raw materials could speak to advanced planning capabilities as stoneworking requires a much different skillset to work and gather materials for than boneworking. The Kapthurin Formation , Kenya, has yielded the oldest evidence of blade and bladelet technology, dating to 545 to 509 thousand years ago. This technology is rare even in the Middle Palaeolithic, and is typically associated with Upper Palaeolithic modern humans. It

22752-429: The vicissitudes which our early forerunners passed through, and the varying fare which overtook them, the name of Charles Dawson is certain of remembrance. We do well to link his name to this picturesque corner of Sussex—the scene of his discovery. I have now the honour of unveiling this monolith dedicated to his memory. The inscription on the memorial stone reads: Here in the old river gravel Mr Charles Dawson, FSA found

22910-577: The work of the Leakey family in eastern Africa. In 1959, Mary Leakey 's discovery of the Zinj fossin ( OH 5 ) at Olduvai Gorge , Tanzania, led to the identification of a new species, Paranthropus boisei . In 1960, the Leakeys discovered the fossil OH 7 , also at Olduvai Gorge, and assigned it to a new species, Homo habilis . In 1972, Bernard Ngeneo, a fieldworker working for Richard Leakey , discovered

23068-432: Was a forgery and demonstrating that the fossil was a composite of three distinct species. It consisted of a human skull of medieval age, the 500-year-old lower jaw of an orangutan and chimpanzee fossil teeth. Someone had created the appearance of age by staining the bones with an iron solution and chromic acid . Microscopic examination revealed file-marks on the teeth, and it was deduced from this that someone had modified

23226-629: Was beads, though he made no reference to Boucher de Perthes' find, possibly because he was unaware of it. In 2005, Robert Bednarik reexamined the material, and concluded that—because all the Bedfordshire P. globularis fossils are sub-spherical and range 10–18 mm (0.39–0.71 in) in diameter, despite this species having a highly variable shape—they were deliberately chosen. They appear to have been bored through completely or almost completely by some parasitic creature (i. e., through natural processes), and were then percussed on what would have been

23384-580: Was difficult at the time to properly define a unique species), they argued that at least these Middle Pleistocene specimens should be allocated to H. (s.?) heidelbergensis or " H. (s.?) rhodesiensis " (depending on, respectively, the inclusion or exclusion of the Mauer mandible) to formally recognize their similarity. Further work most influentially by Stringer, palaeoanthropologist Ian Tattersall , and human evolutionary biologist Phillip Rightmire reported further differences between Middle Pleistocene Afro-European specimens and H. erectus sensu stricto ("in

23542-482: Was first published in 1952, shortly before the fraud was confirmed, and has since been republished 5 times (most recently in 2007). Creationists often cite the hoax (along with Nebraska Man ) as evidence of an alleged dishonesty of paleontologists who study human evolution, although scientists themselves had exposed the Piltdown hoax (and the Nebraska Man incident was not a deliberate fraud). In November 2003,

23700-514: Was in many ways similar to that of a modern human, except for the occiput (the part of the skull that sits on the spinal column ), and brain size , which was about two-thirds that of a modern human. He went on to indicate that, save for two human-like molar teeth, the jaw bone was indistinguishable from that of a modern, young chimpanzee . From the British Museum's reconstruction of the skull, Woodward proposed that Piltdown Man represented an evolutionary missing link between apes and humans, since

23858-446: Was itself controversial. In August 1913, Woodward, Dawson and Teilhard de Chardin began a systematic search of the spoil heaps specifically to find the missing canines. Teilhard de Chardin soon found a canine that, according to Woodward, fitted the jaw perfectly. A few days later, Teilhard de Chardin moved to France and took no further part in the discoveries. Noting that the tooth "corresponds exactly with that of an ape", Woodward expected

24016-532: Was made of hard yew wood. The Schöningen spears may have had a range of up to 35 m (115 ft), though would have been more effective short range within about 5 m (16 ft), making them effective distance weapons either against prey or predators. Besides these two localities, the only other site which provides solid evidence of European spear technology is the 120,000-year-old Lehringen site, district of Verden , in Lower Saxony , Germany, where

24174-472: Was maturing. If so, the individual from the Berg Aukas Mine would probably have had proportions similar to Kabwe 1. The human body plan had evolved in H. ergaster , and characterises all later Homo species, but among the more derived members there are two distinct morphs: A narrow-chested and gracile build like modern humans, and a broader-chested and robust build like Neanderthals. It

24332-479: Was not a 'one-off' hoax, more the culmination of a life's work." In addition, Harry Morris, an acquaintance of Dawson, had come into possession of one of the flints obtained by Dawson at the Piltdown gravel pit. He suspected that it had been artificially aged – "stained by C. Dawson with intent to defraud". He remained deeply suspicious of Dawson for many years to come, though he never sought to discredit him publicly, possibly because it would have been an argument against

24490-456: Was once assumed that the Neanderthal build was unique to Neanderthals based on the gracile H. ergaster partial skeleton "KNM WT-15000" (" Turkana Boy "), but the discovery of some Middle Pleistocene skeletal elements (though generally fragmentary and few and far between) seems to suggest Middle Pleistocene humans overall featured a more Neanderthal morph. Thus, the modern human morph may be unique to modern humans, evolving quite recently. This

24648-407: Was quoted as saying: "Conan Doyle was known to play golf at the Piltdown site and had even given Dawson a lift in his car to the area, but he was a public man and very busy[,] and it is very unlikely that he would have had the time [to create the hoax]. So there are some coincidences, but I think they are just coincidences. When you look at the fossil evidence[,] you can only associate Dawson with all

24806-516: Was responsible for the fraudulent evidence. In 1912, Charles Dawson claimed that he had discovered the " missing link " between early apes and man. In February 1912, Dawson contacted Arthur Smith Woodward , Keeper of Geology at the Natural History Museum , stating he had found a section of a human-like skull in Pleistocene gravel beds near Piltdown, East Sussex . That summer, Dawson and Woodward purportedly discovered more bones and artifacts at

24964-468: Was such a crudely forged 'early tool' that it may have been planted to cast doubt upon the other finds, the 'Earliest Englishman' in effect being recovered with the earliest evidence for the game of cricket. This seems to have been part of a wider attempt, by disaffected members of the Sussex archaeological community, to expose Dawson's activities, other examples being the obviously fraudulent 'Maresfield Map',
