141-478: Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor , the mechanism by which this occurred was not understood, creating the species problem . Ernst Mayr approached the problem with a new definition for species. In his book Systematics and the Origin of Species (1942) he wrote that a species is not just a group of morphologically similar individuals, but

282-442: A common ancestor is now generally accepted and considered a fundamental scientific concept. In a joint publication with Alfred Russel Wallace , he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection , in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding . Darwin has been described as one of

423-451: A genealogical branching of a single evolutionary tree , in which "It is absurd to talk of one animal being higher than another", thereby discarding Lamarck's idea of independent lineages progressing to higher forms. While developing this intensive study of transmutation, Darwin became mired in more work. Still rewriting his Journal , he took on editing and publishing the expert reports on his collections, and with Henslow's help obtained

564-449: A quarantine house for Plague at the city gates, which in 1727 was rechristened by the "soldier king" Friedrich Wilhelm: "Es soll das Haus die Charité heißen" (called Charité [French for charity ]). By 1829 the site became Friedrich Wilhelm University's medical campus and remained so until 1927 when the more modern University Hospital was constructed. The university started a natural history collection in 1810, which by 1889, required

705-628: A "Triple Crown in Biology," he won this crown too. Mayr was co-author of six global reviews of bird species new to science (listed below). Mayr said he was an atheist in regards to "the idea of a personal God" because "there is nothing that supports [it]". As a traditionally-trained biologist, Mayr was often highly critical of early mathematical approaches to evolution, such as those of J.B.S. Haldane , and famously called such approaches "beanbag genetics" in 1959. He maintained that factors such as reproductive isolation had to be taken into account. In

From 1945 to 1948, 18 other students and teachers were arrested or abducted, many missing for weeks, and some were taken to the Soviet Union and executed. Many of the students targeted by Soviet persecution were active in the liberal or social democratic resistance against

987-562: A 230-page "Essay", to be expanded with his research results if he died prematurely. In November, the anonymously published sensational best-seller Vestiges of the Natural History of Creation brought wide interest in transmutation. Darwin scorned its amateurish geology and zoology, but carefully reviewed his own arguments. Controversy erupted, and it continued to sell well despite contemptuous dismissal by scientists. Darwin completed his third geological book in 1846. He now renewed

1128-845: A Bachelor of Arts degree as the first step towards becoming an Anglican country parson . Darwin was unqualified for Cambridge's Tripos exams and was required instead to join the ordinary degree course. He preferred riding and shooting to studying. During the first few months of Darwin's enrolment at Christ's College, his second cousin William Darwin Fox was still studying there. Fox impressed him with his butterfly collection, introducing Darwin to entomology and influencing him to pursue beetle collecting. He did this zealously and had some of his finds published in James Francis Stephens ' Illustrations of British entomology (1829–1932). Through Fox, Darwin became

1269-673: A Treasury grant of £1,000 to sponsor this multi-volume Zoology of the Voyage of H.M.S. Beagle , a sum equivalent to about £115,000 in 2021. He stretched the funding to include his planned books on geology, and agreed to unrealistic dates with the publisher. As the Victorian era began, Darwin pressed on with writing his Journal , and in August 1837 began correcting printer's proofs . As Darwin worked under pressure, his health suffered. On 20 September, he had "an uncomfortable palpitation of

1410-591: A beginning to each crop of species". Darwin's book The Structure and Distribution of Coral Reefs on his theory of atoll formation was published in May 1842 after more than three years of work, and he then wrote his first "pencil sketch" of his theory of natural selection. To escape the pressures of London, the family moved to rural Down House in Kent in September. On 11 January 1844, Darwin mentioned his theorising to

1551-547: A book on geology. When they reached Brazil, Darwin was delighted by the tropical forest , but detested the sight of slavery there , and disputed this issue with FitzRoy. The survey continued to the south in Patagonia . They stopped at Bahía Blanca , and in cliffs near Punta Alta Darwin made a major find of fossil bones of huge extinct mammals beside modern seashells, indicating recent extinction with no signs of change in climate or catastrophe. He found bony plates like

1692-718: A break and went "geologising" in Scotland. He visited Glen Roy in glorious weather to see the parallel "roads" cut into the hillsides at three heights. He later published his view that these were marine-raised beaches, but then had to accept that they were shorelines of a proglacial lake . Fully recuperated, he returned to Shrewsbury in July 1838. Used to jotting down daily notes on animal breeding, he scrawled rambling thoughts about marriage, career and prospects on two scraps of paper, one with columns headed "Marry" and "Not Marry" . Advantages under "Marry" included "constant companion and

1833-471: A calm spell. On their first stop ashore at St Jago in Cape Verde, Darwin found that a white band high in the volcanic rock cliffs included seashells. FitzRoy had given him the first volume of Charles Lyell 's Principles of Geology , which set out uniformitarian concepts of land slowly rising or falling over immense periods, and Darwin saw things Lyell's way, theorising and thinking of writing

1974-540: A central role in the species problem debate over what was the best species concept . He staunchly defended the biological species concept against the many definitions of "species" that others proposed. Mayr was an outspoken defender of the scientific method and was known to critique sharply science on the edge. As a notable example, in 1995, he criticized the Search for Extra-Terrestrial Intelligence (SETI), as conducted by fellow Harvard professor Paul Horowitz , as being

2115-562: A close friend and follower of botany professor John Stevens Henslow . He met other leading parson-naturalists who saw scientific work as religious natural theology , becoming known to these dons as "the man who walks with Henslow". When his own exams drew near, Darwin applied himself to his studies and was delighted by the language and logic of William Paley 's Evidences of Christianity (1795). In his final examination in January 1831, Darwin did well, coming tenth out of 178 candidates for

2256-412: A copy of his journal for his family. He had some expertise in geology, beetle collecting and dissecting marine invertebrates, but in all other areas, was a novice and ably collected specimens for expert appraisal. Despite suffering badly from seasickness, Darwin wrote copious notes while on board the ship. Most of his zoology notes are about marine invertebrates, starting with plankton collected during

2397-596: A fascination and expertise in marine invertebrates, dating back to his student days with Grant, by dissecting and classifying the barnacles he had collected on the voyage, enjoying observing beautiful structures and thinking about comparisons with allied structures. In 1847, Hooker read the "Essay" and sent notes that provided Darwin with the calm critical feedback that he needed, but would not commit himself and questioned Darwin's opposition to continuing acts of creation . In an attempt to improve his chronic ill health, Darwin went in 1849 to Dr. James Gully 's Malvern spa and

2538-529: A fortnight mapping strata in Wales. After leaving Sedgwick in Wales, Darwin spent a few days with student friends at Barmouth . He returned home on 29 August to find a letter from Henslow proposing him as a suitable (if unfinished) naturalist for a self-funded supernumerary place on HMS  Beagle with captain Robert FitzRoy , a position for a gentleman rather than "a mere collector". The ship

2679-532: A freed black slave who had accompanied Charles Waterton in the South American rainforest . In Darwin's second year at the university, he joined the Plinian Society , a student natural-history group featuring lively debates in which radical democratic students with materialistic views challenged orthodox religious concepts of science. He assisted Robert Edmond Grant 's investigations of

2820-473: A friend in old age ... better than a dog anyhow", against points such as "less money for books" and "terrible loss of time". Having decided in favour of marriage, he discussed it with his father, then went to visit his cousin Emma on 29 July. At this time he did not get around to proposing, but against his father's advice, he mentioned his ideas on transmutation. He married Emma on 29 January 1839 and they were

2961-490: A gene is never visible to natural selection, and in the genotype, it is always in the context with other genes, and the interaction with those other genes make a particular gene either more favorable or less favorable. In fact, Dobzhansky , for instance, worked quite a bit on so-called lethal chromosomes which are highly successful in one combination, and lethal in another. Therefore people like Dawkins in England who still think

3102-530: A giant capybara . The armour fragments were actually from Glyptodon , a huge armadillo-like creature, as Darwin had initially thought. These extinct creatures were related to living species in South America. In mid-December, Darwin took lodgings in Cambridge to arrange expert classification of his collections, and prepare his own research for publication. Questions of how to combine his diary into

3243-556: A giant version of the armour on local armadillos . From a jaw and tooth he identified the gigantic Megatherium , then from Cuvier's description thought the armour was from this animal. The finds were shipped to England, and scientists found the fossils of great interest. In Patagonia, Darwin came to wrongly believe the territory was devoid of reptiles. On rides with gauchos into the interior to explore geology and collect more fossils, Darwin gained social, political and anthropological insights into both native and colonial people at

3384-506: A great name among the Naturalists of Europe". On 2 October 1836, Beagle anchored at Falmouth , Cornwall. Darwin promptly made the long coach journey to Shrewsbury to visit his home and see relatives. He then hurried to Cambridge to see Henslow, who advised him on finding available naturalists to catalogue Darwin's animal collections and to take on the botanical specimens. Darwin's father organised investments, enabling his son to be

3525-591: A group that can breed only among themselves, excluding all others. When populations within a species become isolated by geography, feeding strategy, mate choice , or other means, they may start to differ from other populations through genetic drift and natural selection , and over time may evolve into new species. The most significant and rapid genetic reorganization occurs in extremely small populations that have been isolated (as on islands). His theory of peripatric speciation (a more precise form of allopatric speciation which he advanced), based on his work on birds,

3666-410: A marvelous job of popularizing Darwinism. But Dawkins' basic theory of the gene being the object of evolution is totally non-Darwinian. I would not call him the greatest Darwinian. Mayr insisted that the entire genome should be considered as the target of selection , rather than individual genes : The idea that a few people have about the gene being the target of selection is completely impractical;

3807-515: A minor role to natural selection, and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. Darwin's scientific discovery is the unifying theory of the life sciences , explaining the diversity of life . Darwin was born in Shrewsbury , Shropshire, on 12 February 1809, at his family's home, The Mount . He

3948-416: A model for institutions like Johns Hopkins University . Further, it has been claimed that "the 'Humboldtian' university became a model for the rest of Europe [...] with its central principle being the union of teaching and research in the work of the individual scholar or scientist." In addition to the strong anchoring of traditional subjects, such as science, law, philosophy, history, theology and medicine,

4089-645: A much larger number of permanent assistant professors, lecturers and other middle level academic positions. After reunification, these positions were abolished or converted to temporary posts for consistency with the West German system. As a result, only 10% of the mid-level academics in Humboldt-Universität still had a position in 1998. Through the transformations, the university's research and exchange links with Eastern European institutions were maintained and stabilized. Today, Humboldt University

He was survived by two daughters (Christa Menzel and Susanne Harrison), five grandchildren and 10 great-grandchildren. The awards that Mayr received include the National Medal of Science , the Balzan Prize , the Sarton Medal of the History of Science Society , the International Prize for Biology ,

4371-405: A passion for work, such an interest for things that are not petty student intrigues, such an inclination for the sciences, such calm and such silence. Compared to this temple of work, the other universities appear like public houses." The university has been home to many of Germany's greatest thinkers of the past two centuries, among them the subjective idealist philosopher Johann Gottlieb Fichte ,

4512-413: A population. In many of his writings, Mayr rejected reductionism in evolutionary biology, arguing that evolutionary pressures act on the whole organism, not on single genes, and that genes can have different effects depending on the other genes present. He advocated a study of the whole genome , rather than of only isolated genes. After articulating the biological species concept in 1942, Mayr played

4653-539: A programmer of laws. Darwin stayed with his freethinking brother Erasmus, part of this Whig circle and a close friend of the writer Harriet Martineau , who promoted the Malthusianism that underpinned the controversial Whig Poor Law reforms to stop welfare from causing overpopulation and more poverty. As a Unitarian, she welcomed the radical implications of transmutation of species , promoted by Grant and younger surgeons influenced by Geoffroy . Transmutation

4794-591: A sand beach. He theorised that as the land rose, oceanic islands sank, and coral reefs round them grew to form atolls . On the geologically new Galápagos Islands , Darwin looked for evidence attaching wildlife to an older "centre of creation", and found mockingbirds allied to those in Chile but differing from island to island. He heard that slight variations in the shape of tortoise shells showed which island they came from, but failed to collect them, even after eating tortoises taken on board as food. In Australia,

4935-517: A self-funded gentleman scientist , and an excited Darwin went around the London institutions being fêted and seeking experts to describe the collections. British zoologists at the time had a huge backlog of work, due to natural history collecting being encouraged throughout the British Empire, and there was a danger of specimens just being left in storage. Charles Lyell eagerly met Darwin for

The preexisting Tierarznei School, founded in 1790 and absorbed by the university, in 1934 formed the basis of the Veterinary Medicine Facility (Grundstock der Veterinärmedizinischen Fakultät). Also the Landwirtschaftliche Hochschule Berlin (Agricultural University of Berlin), founded in 1881 was affiliated with the Agricultural Faculties of

5217-526: A series of books, and in his final book, The Formation of Vegetable Mould, through the Actions of Worms (1881), he examined earthworms and their effect on soil. Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species . By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact . However, many initially favoured competing explanations that gave only

5358-484: A similar fashion, Mayr was also quite critical of molecular evolution studies such as those of Carl Woese . Current molecular studies in evolution and speciation indicate that although allopatric speciation is the norm, there are numerous cases of sympatric speciation in groups with greater mobility, such as birds. The precise mechanisms of sympatric speciation, however, are usually a form of microallopatry enabled by variations in niche occupancy among individuals within

5499-719: A similarity between farmers picking the best stock in selective breeding, and a Malthusian Nature selecting from chance variants so that "every part of newly acquired structure is fully practical and perfected", thinking this comparison "a beautiful part of my theory". He later called his theory natural selection , an analogy with what he termed the "artificial selection" of selective breeding. On 11 November, he returned to Maer and proposed to Emma, once more telling her his ideas. She accepted, then in exchanges of loving letters she showed how she valued his openness in sharing their differences, while expressing her strong Unitarian beliefs and concerns that his honest doubts might separate them in

Further south, he saw stepped plains of shingle and seashells as raised beaches at a series of elevations. He read Lyell's second volume and accepted its view of "centres of creation" of species, but his discoveries and theorising challenged Lyell's ideas of smooth continuity and of extinction of species.

Even as a centenarian , he continued to write books. On his 100th birthday, he was interviewed by Scientific American magazine. Mayr died on 3 February 2005 in his retirement home in Bedford, Massachusetts , after a short illness. He had married fellow German Margarete "Gretel" Simon in May 1935 (they had met at

6063-466: A waste of university and student resources for its inability to address and answer a scientific question. Over 60 eminent scientists, led by Carl Sagan , rebutted the criticism. Mayr rejected the idea of a gene-centered view of evolution and starkly but politely criticised Richard Dawkins 's ideas: The funny thing is if in England, you ask a man in the street who the greatest living Darwinian is, he will say Richard Dawkins. And indeed, Dawkins has done

Mayr was endlessly interested in ornithology and "chose Greifswald at the Baltic for my studies for no other reason than that ... it was situated in the ornithologically most interesting area." Although he ostensibly planned to become a physician, he was "first and foremost an ornithologist." During the first semester break Stresemann gave him

The university consists of three different campuses, namely Campus Mitte, Campus Nord and Campus Adlershof. Its main building is located in the centre of Berlin at the boulevard Unter den Linden and

6486-609: Is based on key facts and the inferences drawn from them, which Mayr summarised as follows: In relation to the publication of Darwin's Origins of Species , Mayr identified philosophical implications of evolution: Charles Darwin Charles Robert Darwin ( / ˈ d ɑːr w ɪ n / DAR -win ; 12 February 1809 – 19 April 1882) was an English naturalist , geologist , and biologist , widely known for his contributions to evolutionary biology .

The university has a student enrollment of around 35,000 students, and offers degree programs in some 171 disciplines from undergraduate to post-doctorate level. Its main campus is located on the Unter den Linden boulevard in central Berlin. The university is known worldwide for pioneering

6768-471: Is known as a Malthusian catastrophe . Darwin was well-prepared to compare this to Augustin de Candolle 's "warring of the species" of plants and the struggle for existence among wildlife, explaining how numbers of a species kept roughly stable. As species always breed beyond available resources, favourable variations would make organisms better at surviving and passing the variations on to their offspring, while unfavourable variations would be lost. He wrote that

It honors basic research in fields that do not qualify for Nobel Prizes and is administered by the same organization as the Nobel Prize. In 2001, Mayr received the Golden Plate Award of the American Academy of Achievement . Since winning Balzan Prize, Crafoord Prize and the International Prize for Biology, are usually regarded as

Mayr is sometimes credited with inventing modern philosophy of biology , particularly the part related to evolutionary biology , which he distinguished from physics due to its introduction of (natural) history into science. Mayr

For departments on social sciences and humanities, the faculty was subjected to a "liquidation" process, in which contracts of employees were terminated and positions were made open to new academics, mainly West Germans. Older professors were offered early retirement. The East German higher education system included

It was generally regarded as the world's preeminent university for the natural sciences during the 19th and early 20th century, as the university is linked to major breakthroughs in physics and other sciences by its professors, such as Albert Einstein . Past and present faculty and notable alumni include 57 Nobel Prize laureates (the most of any German university), as well as scholars and academics including Albert Einstein , Hermann von Helmholtz , Emil du Bois-Reymond , Robert Koch , Theodor Mommsen , Karl Marx , Friedrich Engels , Otto von Bismarck , W.

On 17 February, Darwin was elected to the Council of the Geological Society, and Lyell's presidential address presented Owen's findings on Darwin's fossils, stressing geographical continuity of species as supporting his uniformitarian ideas. Early in March, Darwin moved to London to be near this work, joining Lyell's social circle of scientists and experts such as Charles Babbage , who described God as

He found the Aborigines "good-humoured & pleasant", their numbers depleted by European settlement. FitzRoy investigated how the atolls of the Cocos (Keeling) Islands had formed, and the survey supported Darwin's theorising. FitzRoy began writing

10293-618: The Wedgwoods were adopting Anglicanism . Robert Darwin, a freethinker , had baby Charles baptised in November 1809 in the Anglican St Chad's Church, Shrewsbury , but Charles and his siblings attended the local Unitarian Church with their mother. The eight-year-old Charles already had a taste for natural history and collecting when he joined the day school run by its preacher in 1817. That July, his mother died. From September 1818, he joined his older brother Erasmus in attending

10434-459: The afterlife. While he was house-hunting in London, bouts of illness continued and Emma wrote urging him to get some rest, almost prophetically remarking "So don't be ill any more my dear Charley till I can be with you to nurse you." He found what they called "Macaw Cottage" (because of its gaudy interiors) in Gower Street , then moved his "museum" in over Christmas. On 24 January 1839, Darwin

10575-506: The anatomy and life cycle of marine invertebrates in the Firth of Forth , and on 27 March 1827 presented at the Plinian his own discovery that black spores found in oyster shells were the eggs of a skate leech . One day, Grant praised Lamarck 's evolutionary ideas . Darwin was astonished by Grant's audacity, but had recently read similar ideas in his grandfather Erasmus' journals. Darwin

10716-437: The botanist Joseph Dalton Hooker , writing with melodramatic humour "it is like confessing a murder". Hooker replied, "There may, in my opinion, have been a series of productions on different spots, & also a gradual change of species. I shall be delighted to hear how you think that this change may have taken place, as no presently conceived opinions satisfy me on the subject." By July, Darwin had expanded his "sketch" into

10857-461: The center of the square. It consists of a glass panel embedded in the pavement that looks into a large, subterranean white room with empty shelf space for 20,000 volumes, along with a plaque bearing an epigraph taken from an 1820 work by the great German-Jewish writer Heinrich Heine : " Das war ein Vorspiel nur, dort wo man Bücher verbrennt, verbrennt man am Ende auch Menschen. " ("This

10998-622: The collection was relocated to the building of the Berlin State Library . During the Weimar Period the library contained 831,934 volumes (1930) and was thus one of the leading university libraries in Germany at that time. During the Nazi book burnings in 1933, no volumes from the university library were destroyed. The loss through World War II was comparatively small. In 2003, natural science-related books were outhoused to

11139-515: The condition that he completed his doctoral studies in 16 months. Mayr completed his doctorate in ornithology at the University of Berlin under Dr. Carl Zimmer, who was a full professor ( Ordentlicher Professor ), on 24 June 1926 at the age of 21. On 1 July he accepted the position offered to him at the museum for a monthly salary of 330.54 Reichsmark. At the International Zoological Congress at Budapest in 1927, Mayr

11280-487: The date of its opening. In 1810, at the time of the opening, the university established the first academic chair in the field of history in the world. From 1828 to 1945, the school was named the "Royal Friedrich Wilhelm University of Berlin", in honor of its founder. Ludwig Feuerbach , then one of the students, made a comment about the university in 1826: "There is no question here of drinking, duelling and pleasant communal outings; in no other university can you find such

11421-542: The duties of Secretary of the Geological Society. After initially declining the work, he accepted the post in March 1838. Despite the grind of writing and editing the Beagle reports, Darwin made remarkable progress on transmutation, taking every opportunity to question expert naturalists and, unconventionally, people with practical experience in selective breeding such as farmers and pigeon fanciers . Over time, his research drew on information from his relatives and children,

11562-557: The economy of nature". University of Berlin The Humboldt University of Berlin (German: Humboldt-Universität zu Berlin , abbreviated HU Berlin ) is a public research university in the central borough of Mitte in Berlin , Germany. The university was established by Frederick William III on the initiative of Wilhelm von Humboldt , Johann Gottlieb Fichte and Friedrich Daniel Ernst Schleiermacher as

11703-713: The family butler, neighbours, colonists and former shipmates. He included mankind in his speculations from the outset, and on seeing an orangutan in the zoo on 28 March 1838 noted its childlike behaviour. The strain took a toll, and by June he was being laid up for days on end with stomach problems, headaches and heart symptoms. For the rest of his life, he was repeatedly incapacitated with episodes of stomach pains, vomiting, severe boils , palpitations, trembling and other symptoms, particularly during times of stress, such as attending meetings or making social visits. The cause of Darwin's illness remained unknown, and attempts at treatment had only ephemeral success. On 23 June, he took

11844-597: The first time on 29 October and soon introduced him to the up-and-coming anatomist Richard Owen , who had the facilities of the Royal College of Surgeons to work on the fossil bones collected by Darwin. Owen's surprising results included other gigantic extinct ground sloths as well as the Megatherium Darwin had identified, a near complete skeleton of the unknown Scelidotherium and a hippopotamus -sized rodent -like skull named Toxodon resembling

11985-640: The first unofficial lectures were given in the building in the winter of 1809. Humboldt faced great resistance to his ideas as he set up the university. He submitted his resignation to the King in April 1810, and was not present when the school opened that fall. The first students were admitted on 6 October 1810, and the first semester started on 10 October 1810, with 256 students and 52 lecturers in faculties of law, medicine, theology and philosophy under rector Theodor Schmalz. The university celebrates 15 October 1810 as

12126-431: The gene is the target of selection are evidently wrong. In the 30s and 40s, it was widely accepted that genes were the target of selection, because that was the only way they could be made accessible to mathematics , but now we know that it is really the whole genotype of the individual, not the gene. Except for that slight revision, the basic Darwinian theory hasn't changed in the last 50 years. Darwin's theory of evolution

12267-582: The heart", so his doctors urged him to "knock off all work" and live in the country for a few weeks. After visiting Shrewsbury, he joined his Wedgwood relatives at Maer Hall , Staffordshire, but found them too eager for tales of his travels to give him much rest. His charming, intelligent, and cultured cousin Emma Wedgwood , nine months older than Darwin, was nursing his invalid aunt. His uncle Josiah pointed out an area of ground where cinders had disappeared under loam and suggested that this might have been

12408-472: The highest aim of natural philosophy as understanding such laws through inductive reasoning based on observation, and Alexander von Humboldt 's Personal Narrative of scientific travels in 1799–1804. Inspired with "a burning zeal" to contribute, Darwin planned to visit Tenerife with some classmates after graduation to study natural history in the tropics. In preparation, he joined Adam Sedgwick 's geology course, then on 4 August travelled with him to spend

12549-662: The interior, discovered several species of flora and fauna, while remaining only steps ahead of the Australian patrols sent to capture him. He returned to Germany in 1930. Mayr moved to the United States in 1931 to take up a curatorial position at the American Museum of Natural History, where he played the important role of brokering and acquiring the Walter Rothschild collection of bird skins, which

12690-610: The lakes of Moritzburg , the Frauenteich, he spotted what he identified as a red-crested pochard . The species had not been seen in Saxony since 1845 and the local club argued about the identity. Raimund Schelcher (1891–1979) of the club then suggested that Mayr visit his classmate Erwin Stresemann on his way to Greifswald, where Mayr was to begin his medical studies. After a tough interrogation, Stresemann accepted and published

12831-694: The local birdwatchers: "In those early years in New York when I was a stranger in a big city, it was the companionship and later friendship which I was offered in the Linnean Society that was the most important thing in my life." Mayr also greatly influenced the American ornithologist Margaret Morse Nice . Mayr encouraged her to correspond with European ornithologists and helped her in her landmark study on song sparrows . Nice wrote to Joseph Grinnell in 1932, trying to get foreign literature reviewed in

12972-480: The most influential figures in human history and was honoured by burial in Westminster Abbey . Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh ; instead, he helped to investigate marine invertebrates . His studies at the University of Cambridge 's Christ's College from 1828 to 1831 encouraged his passion for natural science . However, it

13113-703: The national level. Additionally, in the Times Higher Education World University Rankings for 2024, it was placed at 87th worldwide and 4th within the country. Because of an unresolved dispute over the counting of Nobel laureates before the Second World War – both Humboldt University and the Free University of Berlin claim to be the rightful successor of the Royal Friedrich Wilhelm University of Berlin – both do not appear in

13254-503: The nearby Anglican Shrewsbury School as a boarder . Darwin spent the summer of 1825 as an apprentice doctor, helping his father treat the poor of Shropshire, before going to the well-regarded University of Edinburgh Medical School with his brother Erasmus in October 1825. Darwin found lectures dull and surgery distressing, so he neglected his studies. He learned taxidermy in around 40 daily hour-long sessions from John Edmonstone ,

13395-526: The newly founded library at the Adlershof campus, which is dedicated solely to the natural sciences. Since the premises of the State Library had to be cleared in 2005, a new library building was erected close to the main building in the center of Berlin. The "Jacob und Wilhelm Grimm-Zentrum" (Jacob and Wilhelm Grimm Centre, Grimm Zentrum, or GZ as referred to by students) opened in 2009. In total,

13536-499: The number of top managers in the German economy, Humboldt-Universität ranked 53rd in 2019. In 2020, the American U.S. News & World Report listed Humboldt-Universität as the 82nd best in the world, climbing eight positions, being among the 100 best in the world in 17 areas out of 29 ranked. HU students can study abroad for a semester or a year at partner institutions such as the University of Warwick , Princeton University , and

13677-433: The official Narrative of the Beagle voyages, and after reading Darwin's diary, he proposed incorporating it into the account. Darwin's Journal was eventually rewritten as a separate third volume, on geology and natural history. In Cape Town , South Africa, Darwin and FitzRoy met John Herschel, who had recently written to Lyell praising his uniformitarianism as opening bold speculation on "that mystery of mysteries,

13818-580: The old Friedrich Wilhelm University. The name of the Free University refers to West Berlin's perceived status as part of the Western " free world ", in contrast to the "unfree" Communist world in general and the "unfree" communist-controlled university in East Berlin in particular. Because the historical name, the Royal Friedrich Wilhelm University of Berlin, had monarchic origins, the school

13959-496: The origin of species". Without telling Darwin, extracts from his letters to Henslow had been read to scientific societies, printed as a pamphlet for private distribution among members of the Cambridge Philosophical Society , and reported in magazines, including The Athenaeum . Darwin first heard of this at Cape Town, and at Ascension Island read of Sedgwick's prediction that Darwin "will have

14100-522: The parents of ten children, seven of whom survived to adulthood. Continuing his research in London, Darwin's wide reading now included the sixth edition of Malthus 's An Essay on the Principle of Population . On 28 September 1838, he noted its assertion that human "population, when unchecked, goes on doubling itself every twenty-five years, or increases in a geometrical ratio", a geometric progression so that population soon exceeds food supply in what

14241-677: The physicians Johannes Peter Müller , Emil du Bois-Reymond , Albrecht von Graefe , Rudolf Virchow , and Robert Koch , contributed to Berlin University's scientific fame. During this period of enlargement, the university gradually expanded to incorporate other previously separate colleges in Berlin. An example would be the Charité , the Pépinière and the Collegium Medico-chirurgicum. In 1710, King Friedrich I had built

14382-573: The possibility that "one species does change into another" to explain the geographical distribution of living species such as the rheas, and extinct ones such as the strange extinct mammal Macrauchenia , which resembled a giant guanaco , a llama relative. Around mid-July, he recorded in his "B" notebook his thoughts on lifespan and variation across generations – explaining the variations he had observed in Galápagos tortoises , mockingbirds, and rheas. He sketched branching descent, and then

14523-520: The replacement of extinct species by others" as "a natural in contradistinction to a miraculous process". When organising his notes as the ship sailed home, Darwin wrote that, if his growing suspicions about the mockingbirds, the tortoises and the Falkland Islands fox were correct, "such facts undermine the stability of Species", then cautiously added "would" before "undermine". He later wrote that such facts "seemed to me to throw some light on

14664-413: The sighting as authentic. Stresemann was very impressed and suggested that, between semesters, Mayr could work as a volunteer in the ornithological section of the museum. Mayr wrote about this event, "It was as if someone had given me the key to heaven." He entered the University of Greifswald in 1923 and, according to Mayr himself, "took the medical curriculum (to satisfy a family tradition) but after only

14805-438: The society concentrated on taxonomy and later became a clearing house for bird banding and sight records. Mayr encouraged his Linnaean Society seminar participants to take up a specific research project of their own. Under Mayr's influence one of them, Joseph Hickey, went on to write A Guide to Birdwatching (1943). Hickey remembered later, "Mayr was our age and invited on all our field trips. The heckling of this German foreigner

14946-673: The staff were fired by the Nazis. It was from the university's library that some 20,000 books by " degenerates " and opponents of the regime were taken to be burned on 10 May of that year in the Opernplatz square (now called the Bebelplatz ) for a demonstration that was protected by the SA and featured a speech by Reich Minister of Propaganda Joseph Goebbels . A monument to this tragic event called The Empty Library can now be found in

15087-408: The struggle for existence which everywhere goes on from long-continued observation of the habits of animals and plants, it at once struck me that under these circumstances favourable variations would tend to be preserved, and unfavourable ones to be destroyed. The result of this would be the formation of new species. Here, then, I had at last got a theory by which to work... By mid-December, Darwin saw

15228-409: The systematics of the taxa. He wrote his first examination of the species in 1846, but did not formally describe it until 1854. FitzRoy's long delayed Narrative was published in May 1839. Darwin's Journal and Remarks got good reviews as the third volume, and on 15 August it was published on its own. Early in 1842, Darwin wrote about his ideas to Charles Lyell, who noted that his ally "denies seeing

15369-487: The theologian Friedrich Schleiermacher , the absolute idealist philosopher G.W.F. Hegel , the Romantic legal theorist Friedrich Carl von Savigny , the anti-optimist philosopher Arthur Schopenhauer , the objective idealist philosopher Friedrich Schelling , cultural critic Walter Benjamin , and famous physicists Albert Einstein and Max Planck . The founders of Marxist theory Karl Marx and Friedrich Engels attended

15510-539: The university after its founder's death. However, these terms were ignored. In 2001, the university acquired the Archive for Sexology from the Robert Koch Institute, which was founded with a large private library donated by Erwin J. Haeberle . This has now been housed at the new Magnus Hirschfeld Center. According to the 2024 QS World University Rankings , the university ranked 120th globally and 7th at

15651-477: The university developed to encompass numerous new scientific disciplines. Alexander von Humboldt , brother of the founder William, promoted the new learning. The construction of modern research facilities in the second half of the 19th century aided the teaching of the natural sciences. Famous researchers, such as the chemist August Wilhelm Hofmann , the physicist Hermann von Helmholtz , the mathematicians Ernst Eduard Kummer , Leopold Kronecker , Karl Weierstrass ,

15792-593: The university library contains about 6.5 million volumes and 9,000 held magazines and journals, and is one of the biggest university libraries in Germany. The books of the Institut für Sexualwissenschaft were destroyed during the Nazi book burnings, and the institute destroyed. Under the terms of the Magnus Hirschfeld Foundation, the government had agreed to continue the work of the institute at

15933-468: The university medical center Charité . The natural sciences, together with computer science and mathematics, are located at Campus Adlershof in the south-east of Berlin. Furthermore, the university continues its tradition of a book sale at the university gates facing Bebelplatz. The university is divided ino 9 faculties: Graduate schools provide structured PhD programmes: Furthermore, there are four central institutes ( Zentralinstitute ) that are part of

16074-473: The university, as did poet Heinrich Heine , novelist Alfred Döblin , founder of structuralism Ferdinand de Saussure , German unifier Otto von Bismarck , Communist Party of Germany founder Karl Liebknecht , African American Pan Africanist W. E. B. Du Bois and European unifier Robert Schuman , as well as the influential surgeon Johann Friedrich Dieffenbach in the early half of the 1800s. The structure of German research-intensive universities served as

16215-470: The university, requiring lectures to be submitted for approval by Socialist Unity Party officials, and piped Soviet propaganda into the cafeteria. This led to strong protests within the student body and faculty. NKVD secret police arrested a number of students in March 1947 as a response. The Soviet Military Tribunal in Berlin-Lichtenberg ruled the students were involved in the formation of

16356-648: The university. In August 1870, in a speech delivered on the eve of war with France, Emil du Bois-Reymond proclaimed that "the University of Berlin, quartered opposite the King's palace, is, by the deed of our foundation, the intellectual bodyguard of the House of Hohenzollern (das geistige Leibregiment des Hauses Hohenzollern)." In 1887, chancellor Otto Bismarck established the Seminar für Orientalische Sprachen  [ de ] (SOS), (usually known in English as

16497-477: The university: Each year, students elect the student parliament ( Studierendenparlament ), which serves as the body of student representatives under German law ( AStA ). When the Royal Library proved insufficient, a new library was founded in 1831, first located in several temporary sites. In 1871–1874 a library building was constructed, following the design of architect Paul Emanuel Spieker. In 1910

16638-420: The voyage began on 27 December 1831; it lasted almost five years. As FitzRoy had intended, Darwin spent most of that time on land investigating geology and making natural history collections, while HMS Beagle surveyed and charted coasts. He kept careful notes of his observations and theoretical speculations, and at intervals during the voyage his specimens were sent to Cambridge together with letters including

16779-421: The voyage, Darwin began detailed investigations and, in 1838, devised his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research, and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay that described the same idea, prompting the immediate joint submission of both their theories to

16920-403: The work of earthworms , inspiring "a new & important theory" on their role in soil formation , which Darwin presented at the Geological Society on 1 November 1837. His Journal was printed and ready for publication by the end of February 1838, as was the first volume of the Narrative , but FitzRoy was still working hard to finish his own volume. William Whewell pushed Darwin to take on

17061-592: Was Eugen Fischer . The Law for the Restoration of the Professional Civil Service (German "Gesetz zur Wiederherstellung des Berufsbeamtentums") resulted in 250 Jewish professors and employees being fired from the university during 1933–1934, as well as numerous doctorates being withdrawn. Students and scholars, and other political opponents of Nazis, were ejected from the university and often deported. During this time nearly one third of all of

17202-707: Was elected a Fellow of the Royal Society (FRS). On 29 January, Darwin and Emma Wedgwood were married at Maer in an Anglican ceremony arranged to suit the Unitarians, then immediately caught the train to London and their new home. Darwin now had the framework of his theory of natural selection "by which to work", as his "prime hobby". His research included extensive experimental selective breeding of plants and animals, finding evidence that species were not fixed and investigating many detailed ideas to refine and substantiate his theory. For fifteen years this work

17343-418: Was a " wren " was in the finch group . Darwin had not labelled the finches by island, but from the notes of others on the ship, including FitzRoy, he allocated species to islands. The two rheas were distinct species, and on 14 March Darwin announced how their distribution changed going southwards. By mid-March 1837, barely six months after his return to England, Darwin was speculating in his Red Notebook on

17484-472: Was anathema to Anglicans defending social order, but reputable scientists openly discussed the subject, and there was wide interest in John Herschel's letter praising Lyell's approach as a way to find a natural cause of the origin of new species. Gould met Darwin and told him that the Galápagos mockingbirds from different islands were separate species, not just varieties, and what Darwin had thought

17625-863: Was awarded the Daniel Giraud Elliot Medal from the National Academy of Sciences in 1967. Mayr was elected a Foreign Member of the Royal Society (ForMemRS) in 1988 . In 1995 he received the Benjamin Franklin Medal for Distinguished Achievement in the Sciences of the American Philosophical Society , of which he was already a member. Mayr never won a Nobel Prize , but he noted that there is no prize for evolutionary biology and that Darwin would not have received one, either. (In fact, there

17766-418: Was being sold in order to pay off a blackmailer. During his time at the museum he produced numerous publications on bird taxonomy, and in 1942 his first book Systematics and the Origin of Species , which completed the evolutionary synthesis started by Darwin. After Mayr was appointed at the American Museum of Natural History, he influenced American ornithological research by mentoring young birdwatchers. Mayr

17907-590: Was but a prelude; where they burn books, they ultimately burn people"). During the Cold War , the university was located in East Berlin . It reopened in 1946 as the University of Berlin, but faced repression from the Soviet Military Administration in Germany , including the persecution of liberal and social democrat students. Almost immediately, the Soviet occupiers started persecuting non-communists and suppressing academic freedom at

18048-650: Was converted into a university building. Damaged during the Allied bombing in World War II , it was rebuilt from 1949 to 1962. In 1967, eight statues from the destroyed Potsdam City Palace were placed on the side wings of the university building. Currently there is discussion about returning the statues to the Potsdam City Palace, which was rebuilt as the Landtag of Brandenburg in 2013. Similar to

18189-418: Was his five-year voyage on HMS  Beagle from 1831 to 1836 that truly established Darwin as an eminent geologist. The observations and theories he developed during his voyage supported Charles Lyell 's concept of gradual geological change . Publication of his journal of the voyage made Darwin famous as a popular author. Puzzled by the geographical distribution of wildlife and fossils he collected on

18330-425: Was in the background to his main occupation of writing on geology and publishing expert reports on the Beagle collections, in particular, the barnacles . The impetus of Darwin's barnacle research came from a collection of a barnacle colony from Chile in 1835, which he dubbed Mr. Arthrobalanus . His confusion over the relationship of this species ( Cryptophialus minutus ) to other barnacles caused him to fixate on

18471-532: Was introduced by Stresemann to banker and naturalist Walter Rothschild , who asked him to undertake an expedition to New Guinea on behalf of himself and the American Museum of Natural History in New York. In New Guinea, Mayr collected several thousand bird skins (he named 38 new bird species during his lifetime) and, in the process also named 38 new orchid species. During his stay in New Guinea, he

18612-730: Was invited to accompany the Whitney South Sea Expedition to the Solomon Islands . Also, while in New Guinea, he visited the Lutheran missionaries Otto Thiele and Christian Keyser, in the Finschhafen district; there, while in conversation with his hosts, he uncovered the discrepancies in Hermann Detzner 's popular book Four Years among Cannibals: New Guinea , in which Detzner claimed to have seen

18753-504: Was no unbridgeable gap between humans and animals. A year on, the mission had been abandoned. The Fuegian they had named Jemmy Button lived like the other natives, had a wife, and had no wish to return to England. Darwin experienced an earthquake in Chile in 1835 and saw signs that the land had just been raised, including mussel -beds stranded above high tide. High in the Andes he saw seashells, and several fossil trees that had grown on

18894-527: Was officially renamed in 1949. Although the Soviet occupational authorities preferred to name the school after a communist leader, university leaders were able to name it the "Humboldt-Universität zu Berlin", after the two Humboldt brothers, a name that was also uncontroversial in the West and capitalized on the fame of the Humboldt name, which is associated with the Humboldtian model of higher education . After

19035-524: Was rather bored by Robert Jameson 's natural-history course, which covered geology – including the debate between neptunism and plutonism . He learned the classification of plants and assisted with work on the collections of the University Museum , one of the largest museums in Europe at the time. Darwin's neglect of medical studies annoyed his father, who sent him to Christ's College, Cambridge , in January 1828, to study for

19176-409: Was surprised at the differences between American and German birding societies. He noted that the German society was "far more scientific, far more interested in life histories and breeding bird species, as well as in reports on recent literature." Mayr organized a monthly seminar under the auspices of the Linnean Society of New York. Under the influence of J.A. Allen, Frank Chapman, and Jonathan Dwight,

19317-574: Was surprised to find some benefit from hydrotherapy . Then, in 1851, his treasured daughter Annie fell ill, reawakening his fears that his illness might be hereditary. She died the same year after a long series of crises. In eight years of work on barnacles, Darwin's theory helped him to find " homologies " showing that slightly changed body parts served different functions to meet new conditions, and in some genera he found minute males parasitic on hermaphrodites , showing an intermediate stage in evolution of distinct sexes . In 1853, it earned him

19458-482: Was the fifth of six children of wealthy society doctor and financier Robert Darwin and Susannah Darwin (née Wedgwood). His grandfathers Erasmus Darwin and Josiah Wedgwood were both prominent abolitionists . Erasmus Darwin had praised general concepts of evolution and common descent in his Zoonomia (1794), a poetic fantasy of gradual creation including undeveloped ideas anticipating concepts his grandson expanded. Both families were largely Unitarian , though

19599-499: Was the second son of Helene Pusinelli and Otto Mayr. His father was a district prosecuting attorney at Würzburg but took an interest in natural history and took the children out on field trips. Mayr learnt all the local birds in Würzburg from his elder brother Otto. He also had access to a natural history magazine for amateurs, Kosmos . His father died just before he was thirteen. The family then moved to Dresden , where he studied at

19740-446: Was to leave in four weeks on an expedition to chart the coastline of South America. Robert Darwin objected to his son's planned two-year voyage, regarding it as a waste of time, but was persuaded by his brother-in-law, Josiah Wedgwood II , to agree to (and fund) his son's participation. Darwin took care to remain in a private capacity to retain control over his collection, intending it for a major scientific institution. After delays,

19881-501: Was tremendous, but he gave tit for tat, and any modern picture of Dr E. Mayr as a very formal person does not square with my memory of the 1930s. He held his own." A group of eight young birdwatchers from The Bronx later became the Bronx County Bird Club , led by Ludlow Griscom . "Everyone should have a problem" was the way one Bronx County Bird Club member recalled Mayr's refrain. Mayr said of his own involvement with
