58-478: Shawwāl stems from the Arabic verb shāla ( شَالَ ), which means to 'lift or carry', generally to take or move things from one place to another. The month was so named because a female camel would normally be carrying a fetus at this time of year in pre-Islamic Arabia . The first day of Shawwāl is Eid al-Fitr ; fasting is prohibited. Some Muslims observe six days of optional fasting during Shawwāl beginning

116-423: A dulla in his throat, a large, inflatable sac that he extrudes from his mouth when in rut to assert dominance and attract females. It resembles a long, swollen, pink tongue hanging out of the side of the camel's mouth. Camels mate by having both male and female sitting on the ground, with the male mounting from behind. The male usually ejaculates three or four times within a single mating session. Camelids are

174-412: A barrier against sand. If sand gets lodged in their eyes, they can dislodge it using their translucent third eyelid (also known as the nictitating membrane). The camels' gait and widened feet help them move without sinking into the sand. The kidneys and intestines of a camel are very efficient at reabsorbing water. Camels' kidneys have a 1:4 cortex to medulla ratio . Thus, the medullary part of

232-502: A camel's kidney occupies twice as much area as a cow's kidney. Secondly, renal corpuscles have a smaller diameter, which reduces surface area for filtration. These two major anatomical characteristics enable camels to conserve water and limit the volume of urine in extreme desert conditions. Camel urine comes out as a thick syrup, and camel faeces are so dry that they do not require drying when used to fuel fires. The camel immune system differs from those of other mammals. Normally,

290-403: A foot taller. Camels can run at up to 65 km/h (40 mph) in short bursts and sustain speeds of up to 40 km/h (25 mph). Bactrian camels weigh 300 to 1,000 kg (660 to 2,200 lb) and dromedaries 300 to 600 kg (660 to 1,320 lb). The widening toes on a camel's hoof provide supplemental grip for varying soil sediments. The male dromedary camel has an organ called

348-454: A greater emphasis on experiments. There are more frequent discontinuities present in paleontology than in neontology, because paleontology involves extinct taxa. Neontology has organisms actually present and available to sample and perform research on. Neontology's research method uses cladistics to examine morphologies and genetics . Neontology data has more emphasis on genetic data and the population structure than paleontology does. When

406-467: A mixture of wool and camel hair was used. By at least 1200 BC the first camel saddles had appeared, and Bactrian camels could be ridden. The first saddle was positioned to the back of the camel, and control of the Bactrian camel was exercised by means of a stick. However, between 500 and 100 BC, Bactrian camels came into military use. New saddles, which were inflexible and bent, were put over

464-491: A name to contrast ourselves with all you folks who study modern organisms in human or ecological time . You therefore become neontologists. We do recognize the unbalanced and parochial nature of this dichotomous division. Neontological evolutionary biology has a temporal perspective between 100 and 1000 years. Neontology's fundamental basis relies on models of natural selection as well as speciation . Neontology's methods, when compared to evolutionary paleontology , have

522-446: A pan- Trypanozoon test, which would also be useful for T. b. brucei , T. b. gambiense , T. b. rhodesiense , and T. equiperdum . The karyotypes of different camelid species have been studied earlier by many groups, but no agreement on chromosome nomenclature of camelids has been reached. A 2007 study flow sorted camel chromosomes, building on the fact that camels have 37 pairs of chromosomes (2n=74), and found that

580-866: A thousand more camels), the outbreak of the American Civil War in 1861 saw the end of the Camel Corps: Texas became part of the Confederacy, and most of the camels were left to wander away into the desert. France created a méhariste camel corps in 1912 as part of the Armée d'Afrique in the Sahara in order to exercise greater control over the camel-riding Tuareg and Arab insurgents, as previous efforts to defeat them on foot had failed. The Free French Camel Corps fought during World War II , and camel-mounted units remained in service until

638-411: A vital means of transport for passengers and cargo. There are three surviving species of camel. The one-humped dromedary makes up 94% of the world's camel population, and the two-humped Bactrian camel makes up 6%. The wild Bactrian camel is a distinct species that is not ancestral to the domestic Bactrian camel, and is now critically endangered , with fewer than 1,000 individuals. The word camel

696-399: Is a camel-llama hybrid bred by scientists to see how closely related the parent species are. Scientists collected semen from a camel via an artificial vagina and inseminated a llama after stimulating ovulation with gonadotrophin injections. The cama is halfway in size between a camel and a llama and lacks a hump. It has ears intermediate between those of camels and llamas, longer legs than

754-430: Is a net decrease in water. Camels have a series of physiological adaptations that allow them to withstand long periods of time without any external source of water. The dromedary camel can drink as seldom as once every 10 days even under very hot conditions, and can lose up to 30% of its body mass due to dehydration. Unlike other mammals, camels' red blood cells are oval rather than circular in shape. This facilitates

812-406: Is a part of biology that, in contrast to paleontology , deals with living (or, more generally, recent ) organisms . It is the study of extant taxa (singular: extant taxon ): taxa (such as species , genera and families ) with members still alive, as opposed to (all) being extinct . For example: A taxon can be classified as extinct if it is broadly agreed or certified that no members of

870-568: Is also used informally in a wider sense, where the more correct term is "camelid", to include all seven species of the family Camelidae : the true camels (the above three species), along with the "New World" camelids: the llama , the alpaca , the guanaco , and the vicuña , which belong to the separate tribe Lamini . Camelids originated in North America during the Eocene , with the ancestor of modern camels, Paracamelus , migrating across

928-504: Is estimated to have stood around nine feet (2.7 metres) tall. The Bactrian camel diverged from the dromedary about 1 million years ago, according to the fossil record. The last camel native to North America was Camelops hesternus , which vanished along with horses , short-faced bears , mammoths and mastodons , ground sloths , sabertooth cats , and many other megafauna as part of the Quaternary extinction event , coinciding with

986-656: Is held in Saudi Arabia. In addition to camel racing and camel milk tasting, the festival holds a camel " beauty pageant " with prize money of $ 57m (£40m). In 2018, 12 camels were disqualified from the beauty contest after their owners were found to have injected them with botox . In a similar incident in 2021, over 40 camels were disqualified. Camel meat and milk are foods that are found in many cuisines, typically in Middle Eastern , North African and some Australian cuisines . Extant taxa Neontology

1044-520: Is reabsorbed into the body as a means to conserve water. Camels eating green herbage can ingest sufficient moisture in milder conditions to maintain their bodies' hydrated state without the need for drinking. The camel's thick coat insulates it from the intense heat radiated from desert sand; a shorn camel must sweat 50% more to avoid overheating. During the summer the coat becomes lighter in color, reflecting light as well as helping avoid sunburn. The camel's long legs help by keeping its body farther from

1102-879: The Achaemenid Persians when fighting Lydia in the Battle of Thymbra (547 BC). The United States Army established the U.S. Camel Corps , stationed in California , in the 19th century. One may still see stables at the Benicia Arsenal in Benicia, California , where they nowadays serve as the Benicia Historical Museum. Though the experimental use of camels was seen as a success ( John B. Floyd , Secretary of War in 1858, recommended that funds be allocated towards obtaining

1160-532: The Arabian Peninsula , dating to around 930 BC. This garnered considerable media coverage, as it is strong evidence that the stories of Abraham , Jacob , Esau , and Joseph were written after this time . The existence of camels in Mesopotamia—but not in the eastern Mediterranean lands—is not a new idea. The historian Richard Bulliet did not think that the occasional mention of camels in

1218-465: The Aravah Valley enable us to pinpoint the introduction of domestic camels to the southern Levant more precisely based on stratigraphic contexts associated with an extensive suite of radiocarbon dates . The data indicate that this event occurred not earlier than the last third of the 10th century [BC] and most probably during this time. The coincidence of this event with a major reorganization of

1276-469: The Battle of Qarqar in 853 BC. Armies have also used camels as freight animals instead of horses and mules. The East Roman Empire used auxiliary forces known as dromedarii , whom the Romans recruited in desert provinces. The camels were used mostly in combat because of their ability to scare off horses at close range (horses are afraid of the camels' scent), a quality famously employed by

1334-465: The Bering land bridge into Asia during the late Miocene , around 6 million years ago. Three species are extant : [REDACTED] [REDACTED] [REDACTED] The average life expectancy of a camel is 40 to 50 years. A full-grown adult dromedary camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in) at the hump. Bactrian camels can be

1392-812: The British Indian Army in World Wars I and II. The Tropas Nómadas (Nomad Troops) were an auxiliary regiment of Sahrawi tribesmen serving in the colonial army in Spanish Sahara (today Western Sahara ). Operational from the 1930s until the end of the Spanish presence in the territory in 1975, the Tropas Nómadas were equipped with small arms and led by Spanish officers. The unit guarded outposts and sometimes conducted patrols on camelback. The annual King Abdulaziz Camel Festival

1450-655: The Gobi Desert . When humans first domesticated camels is disputed. Dromedaries may have first been domesticated by humans in Somalia or South Arabia sometime during the 3rd millennium BC , the Bactrian in central Asia around 2,500 BC, as at Shar-i Sokhta (also known as the Burnt City), Iran . A study from 2016, which genotyped and used world-wide sequencing of modern and ancient mitochondrial DNA (mtDNA), suggested that they were initially domesticated in

1508-592: The Hanafiyya and Hanbaliyya do not place an emphasis on consecutive days, while the strongest opinion of the Malikiyya prefers any six days of the month, consecutively or otherwise. The Islamic calendar is a purely lunar calendar , and its months begin when the first crescent of a new moon is sighted. Since the Islamic lunar year is 11 to 12 days shorter than the solar year , Shawwāl migrates throughout

1566-582: The Ja'fari school do not place any emphasis on the six days being consecutive, while among the Sunnis, the majority of Shafi`i scholars consider it recommended to fast these days consecutively. They based this on a hadith related by Tabarani and others, wherein Muhammad is reported to have said, "Fasting six consecutive days after Eid al-Fitr is like fasting the entire year." Other traditional scholarly sources among

1624-689: The Bible meant that the domestic camels were common in the Holy Land at that time. The archaeologist William F. Albright , writing even earlier, saw camels in the Bible as an anachronism . The official report by Sapir-Hen and Ben-Joseph says: The introduction of the dromedary camel (Camelus dromedarius) as a pack animal to the southern Levant ... substantially facilitated trade across the vast deserts of Arabia, promoting both economic and social change (e.g., Kohler 1984; Borowski 1998: 112–116; Jasmin 2005). This ... has generated extensive discussion regarding

1682-599: The Y-shaped antibody molecules consist of two heavy (or long) chains along the length of the Y, and two light (or short) chains at each tip of the Y. Camels, in addition to these, also have antibodies made of only two heavy chains, a trait that makes them smaller and more durable. These "heavy-chain-only" antibodies, discovered in 1993, are thought to have developed 50 million years ago, after camelids split from ruminants and pigs. Camels suffer from surra caused by Trypanosoma evansi wherever camels are domesticated in

1740-413: The copper industry of the region—attributed to the results of the campaign of Pharaoh Shoshenq I —raises the possibility that the two were connected, and that camels were introduced as part of the efforts to improve efficiency by facilitating trade. Desert tribes and Mongolian nomads use camel hair for tents, yurts , clothing, bedding and accessories. Camels have outer guard hairs and soft inner down, and

1798-477: The date of the earliest domestic camel in the southern Levant (and beyond) (e.g., Albright 1949: 207; Epstein 1971: 558–584; Bulliet 1975; Zarins 1989; Köhler-Rollefson 1993; Uerpmann and Uerpmann 2002; Jasmin 2005; 2006; Heide 2010; Rosen and Saidel 2010; Grigson 2012). Most scholars today agree that the dromedary was exploited as a pack animal sometime in the early Iron Age (not before the 12th century [BC]) and concludes: Current data from copper smelting sites of

1856-524: The day after Eid ul-Fitr since fasting is prohibited on this day. These six days of fasting together with the Ramadan fasts are equivalent to fasting all year round. The reasoning behind this tradition is that a good deed in Islam is rewarded 10 times, hence fasting 30 days during Ramadan and 6 days during Shawwāl is equivalent to fasting the whole year in fulfillment of this obligation. The Shia scholars of

1914-807: The end of French rule over Algeria in 1962. In 1916, the British created the Imperial Camel Corps . It was originally used to fight the Senussi , but was later used in the Sinai and Palestine Campaign in World War I . The Imperial Camel Corps comprised infantrymen mounted on camels for movement across desert, though they dismounted at battle sites and fought on foot. After July 1918, the Corps began to become run down, receiving no new reinforcements, and

1972-399: The fibers may also be sorted by color and age of the animal. The guard hairs can be felted for use as waterproof coats for the herdsmen, while the softer hair is used for premium goods. The fiber can be spun for use in weaving or made into yarns for hand knitting or crochet. Pure camel hair is recorded as being used for western garments from the 17th century onwards, and from the 19th century

2030-491: The flow of red blood cells during dehydration and makes them better at withstanding high osmotic variation without rupturing when drinking large amounts of water. Camels are able to withstand changes in body temperature and water consumption that would kill most other mammals. Their temperature ranges from 34 °C (93 °F) at dawn and steadily increases to 40 °C (104 °F) by sunset, before they cool off at night again. In general, to compare between camels and

2088-463: The ground, which can heat up to 70 °C (158 °F). Dromedaries have a pad of thick tissue over the sternum called the pedestal . When the animal lies down in a sternal recumbent position, the pedestal raises the body from the hot surface and allows cooling air to pass under the body. Camels' mouths have a thick leathery lining, allowing them to chew thorny desert plants. Long eyelashes and ear hairs, together with nostrils that can close, form

2146-629: The group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species (" Lazarus species "), or if previously known extant species are reclassified as members of the taxon. Most biologists, zoologists , and botanists are in practice neontologists, and the term neontologist is used largely by paleontologists referring to non- paleontologists . Stephen Jay Gould said of neontology: All professions maintain their parochialisms , and I trust that nonpaleontological readers will forgive our major manifestation . We are paleontologists, so we need

2204-546: The humps and divided the rider's weight over the animal. In the seventh century BC the military Arabian saddle evolved, which again improved the saddle design slightly. Military forces have used camel cavalries in wars throughout Africa, the Middle East, and their use continues into the modern-day within the Border Security Force (BSF) of India . The first documented use of camel cavalries occurred in

2262-428: The karyotype consisted of one metacentric , three submetacentric, and 32 acrocentric autosomes. The Y is a small metacentric chromosome, while the X is a large metacentric chromosome. The hybrid camel , a hybrid between Bactrian and dromedary camels, has one hump, though it has an indentation 4–12 cm (1.6–4.7 in) deep that divides the front from the back. The hybrid is 2.15 m (7 ft 1 in) at

2320-793: The late Miocene, between 7.5 and 6.5 million years ago. During the Pleistocene, around 3 to 1 million years ago, the North American Camelidae spread to South America as part of the Great American Interchange via the newly formed Isthmus of Panama , where they gave rise to guanacos and related animals. Populations of Paracamelus continued to exist in the North American Arctic into the Early Pleistocene . This creature

2378-470: The llama, and partially cloven hooves . Like the mule , camas are sterile, despite both parents having the same number of chromosomes. The earliest known camel, called Protylopus , lived in North America 40 to 50 million years ago (during the Eocene ). It was about the size of a rabbit and lived in the open woodlands of what is now South Dakota . By 35 million years ago, the Poebrotherium

2436-614: The migration of humans from Asia at the end of the Pleistocene, around 13–11,000 years ago. An extinct giant camel species, Camelus knoblochi roamed Asia during the Late Pleistocene, before becoming extinct around 20,000 years ago. Like horses , camels originated in North America and eventually spread across Beringia to Asia. They survived in the Old World, and eventually humans domesticated them and spread them globally. Along with many other megafauna in North America,

2494-421: The only ungulates to mate in a sitting position. Camels do not directly store water in their humps; they are reservoirs of fatty tissue. When this tissue is metabolized, it yields a greater mass of water than that of the fat processed. This fat metabolization , while releasing energy, causes water to evaporate from the lungs during respiration (as oxygen is required for the metabolic process): overall, there

2552-547: The original wild camels were wiped out during the spread of the first indigenous peoples of the Americas from Asia into North America, 10 to 12,000 years ago; although fossils have never been associated with definitive evidence of hunting. Most camels surviving today are domesticated. Although feral populations exist in Australia , India and Kazakhstan, wild camels survive only in the wild Bactrian camel population of

2610-545: The other great apes . If the concept of an ape-man were based on neontology, then our phenotype would resemble Bigfoot . Since the concept was based on paleontology, the idea of an ape-man could possibly be represented by the fossil hominids. Neontology studies extant (living) taxa and recently extinct taxa, but declaring a taxon to be definitively extinct is difficult. Taxa that have previously been declared extinct may reappear over time. Species that were once considered extinct and then reappear unscathed are characterized by

2668-525: The other livestock, camels lose only 1.3 liters of fluid intake every day while the other livestock lose 20 to 40 liters per day. Maintaining the brain temperature within certain limits is critical for animals; to assist this, camels have a rete mirabile , a complex of arteries and veins lying very close to each other which utilizes countercurrent blood flow to cool blood flowing to the brain. Camels rarely sweat, even when ambient temperatures reach 49 °C (120 °F). Any sweat that does occur evaporates at

2726-542: The patriarchal narratives may refer, at least in some places, to the Bactrian camel", while noting that the camel is not mentioned in relationship to Canaan . Heide and Joris Peters reasserted that conclusion in their 2021 study on the subject. In 2009–2013, excavations in the Timna Valley by Lidar Sapir-Hen and Erez Ben-Yosef discovered what may be the earliest domestic camel bones yet found in Israel or even outside

2784-524: The scientific community accepted the synthetic theory of evolution , taxonomies became phylogenetic . As a result, information gaps arose within the fossil record of species, especially in Homo sapiens . The anthropologists who accepted the synthetic theory reject the idea of an "ape-man" because the concept had mistaken paleontology with neontology. An ape-man, in actuality, would be a primate with traits that would represent anything in between humans and

2842-661: The seasons. The estimated start and end dates for Shawwāl, based on the Umm al-Qura calendar of Saudi Arabia, are: Camel A camel (from Latin : camelus and ‹See Tfd› Greek : κάμηλος ( kamēlos ) from Ancient Semitic : gāmāl ) is an even-toed ungulate in the genus Camelus that bears distinctive fatty deposits known as "humps" on its back. Camels have long been domesticated and, as livestock , they provide food ( camel milk and meat) and textiles (fiber and felt from camel hair ). Camels are working animals especially suited to their desert habitat and are

2900-556: The shoulder and 2.32 m (7 ft 7 in) tall at the hump. It weighs an average of 650 kg (1,430 lb) and can carry around 400 to 450 kg (880 to 990 lb), which is more than either the dromedary or Bactrian can. According to molecular data, the wild Bactrian camel ( C. ferus ) separated from the domestic Bactrian camel ( C. bactrianus ) about 1 million years ago. New World and Old World camelids diverged about 11 million years ago. In spite of this, these species can hybridize and produce viable offspring. The cama

2958-418: The skin level rather than at the surface of their coat; the heat of vaporization therefore comes from body heat rather than ambient heat. Camels can withstand losing 25% of their body weight in water, whereas most other mammals can withstand only about 12–14% dehydration before cardiac failure results from circulatory disturbance. When the camel exhales, water vapor becomes trapped in their nostrils and

3016-532: The southeast Arabian Peninsula, with the Bactrian type later being domesticated around Central Asia. Martin Heide's 2010 work on the domestication of the camel tentatively concludes that humans had domesticated the Bactrian camel by at least the middle of the third millennium somewhere east of the Zagros Mountains , with the practice then moving into Mesopotamia. Heide suggests that mentions of camels "in

For example, a study determined that 36% of supposed mammalian extinction had been proven, while the other 64% had insufficient evidence to be declared extinct or had been rediscovered. Currently, the International Union for Conservation of Nature considers a taxon to be recently extinct if the extinction occurred after 1500 C.E. A recently considered extinct mammal

3132-664: The world, and resultantly camels have evolved trypanolytic antibodies as with many mammals. In the future, nanobody/ single-domain antibody therapy will surpass natural camel antibodies by reaching locations currently unreachable due to natural antibodies' larger size. Such therapies may also be suitable for other mammals. Tran et al. 2009 provides a new reference test for surra ( T. evansi ) of camel. They use recombinant Invariant Surface Glycoprotein 75 (rISG75, an Invariant Surface Glycoprotein ) and ELISA . The Tran test has high test specificity and appears likely to work just as well for T. evansi in other hosts, and for

3190-579: Was disbanded in 1944. Bactrian camels were used by Romanian forces during World War II in the Caucasian region. At the same period the Soviet units operating around Astrakhan in 1942 adopted local camels as draft animals due to shortage of trucks and horses, and kept them even after moving out of the area. Despite severe losses, some of these camels ended up as far west as to Berlin itself . The Bikaner Camel Corps of British India fought alongside

The Corps supported British war operations in Sinai , Palestine, and Syria by transporting supplies to the troops. The Somaliland Camel Corps was created by colonial authorities in British Somaliland in 1912; it

3306-566: Was the Bouvier's red colobus monkey, who was considered extinct up until 2015 when it was rediscovered after 40 years with no recorded sightings. Neontology's fundamental theories rely on biological models of natural selection and speciation that connect genes, the unit of heredity with the mechanism of evolution by natural selection. For example, researchers utilized neontological and paleontological datasets to study nonhuman primate dentition compared with human dentition. In order to understand

The hoofed Stenomylus , which walked on the tips of its toes, also existed around this time, and the long-necked Aepycamelus evolved in the Miocene . The split between the tribes Camelini , which contains modern camels and Lamini , modern llamas , alpacas , vicuñas , and guanacos , is estimated to have occurred over 16 million years ago. The ancestor of modern camels, Paracamelus , migrated into Eurasia from North America via Beringia during
