He was also a renowned [[Taxonomy|taxonomist]], tropical explorer, [[ornithologist]], [[History of science|historian of science]], and [[Natural history|naturalist]].<ref>Rennie, J. (1994) ''Profile: Ernst Mayr &ndash; Darwin's Current Bulldog'', [[Scientific American]] '''271'''(2), 24-25.</ref> His work contributed to the conceptual revolution that led to the [[modern evolutionary synthesis]] of [[Gregor Mendel|Mendelian]] [[genetics]], [[systematics]], and [[Charles Darwin|Darwinian]] [[evolution]], and to the development of the [[Species|biological species concept]].

Neither [[Charles Darwin]] nor anyone else in his time knew the answer to the ''[[species problem]]'': how multiple [[species]] could evolve from a single [[common ancestor]]. Ernst Mayr approached the problem with a new definition for the concept of species. In his book ''[[Systematics and the Origin of Species]]'' (1942) he wrote that a species is not just a group of [[Morphology (biology)|morphologically]] similar individuals, but a group that can [[Breeding in the wild|breed]] only among themselves, excluding all others. When populations within a species become isolated by geography, feeding strategy, mate selection, 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, is still considered a leading mode of [[speciation]], and was the theoretical underpinning for the theory of [[punctuated equilibrium]], proposed by [[Niles Eldredge]] and [[Stephen Jay Gould]]. 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.

==Biography==

Mayr was the second son of Dr. Otto Mayr and his wife Helene, née Pusinelli. His father was a jurist (District Prosecuting
Attorney at [[Würzburg]])<ref>Haffer 2007:12</ref> but took an interest in natural history and took the children out on field trips. He 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]] and he studied at the Staatsgymnasium (“Royal Gymnasium” until 1918) in Dresden-Neustadt and completed his high school education there. In April 1922, while still in high school, he joined the newly founded Saxony Ornithologists’ Association. Here he met Rudolf Zimmermann, who became his ornithological mentor. In February 1923, Mayr passed his high school examination (Abitur) and his mother rewarded him with a pair of binoculars.<ref name = "skvotb">Haffer 2007:22</ref> 

On March 23, 1923 on 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.<ref name = "skvotb"/> After a tough interrogation, Stresemann accepted and published 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."<ref name = "skvotb"/> He entered the [[University of Greifswald]] in 1923 and, according to Mayr himself, "took the medical curriculum (to satisfy a family tradition)."<ref name = "bpdwnh">Mayr & Provine, 1998:p. 413</ref> 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."<ref name = "bpdwnh"/> Although he ostensibly planned to become a physician, he was "first and foremost an ornithologist."<ref name = "bpdwnh"/> During the first semester break Stresemann gave him a test to identify treecreepers and Mayr was able to identify most of the specimens correctly. Stresemann declared that Mayr 'was a born [[systematist]]'.<ref>Haffer 2007:23</ref> In 1925 Stresemann suggested that he give up his medical studies and join the Berlin Museum with the prospect of bird-collecting trips to the tropics on 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 June 24, 1926 at the age of 21. On July 1 he accepted the position offered to him at the Museum for a monthly salary of 330.54 Reichsmark.<ref>Haffer 2007:35</ref>

At the International Zoological Congress at Budapest in 1927, Mayr was introduced by Stresemann to banker and naturalist [[Walter Rothschild, 2nd Baron Rothschild|Walter Rothschild]], who asked him to undertake an expedition to [[New Guinea]], a former [[German colonies|German colony]], 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 26 new bird species during his lifetime) and, in the process also named 38 new [[orchid]] species. During his stay in New Guinea, he was invited to accompany the [[Whitney South Seas 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|Hermann Detzner's]] popular book, ''Four Years among the Cannibals in German Guinea from 1914 to the Truce,'' in which Detzner claimed to have seen 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 and in 1931 he accepted a curatorial position at the [[American Museum of Natural History]], where he played the important role of brokering and acquiring the [[Walter Rothschild, 2nd Baron Rothschild|Walter Rothschild]] collection of bird skins, which 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 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."<ref name=barrow>Barrow, Mark V. 1998. A Passion for Birds: American Ornithology after Audubon. Princeton University Press. ISBN 0-691-04402-3</ref> 

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, the society concentrated on taxonomy and later became a clearing house for bird banding and sight records.<ref name=barrow /> 

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 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.<ref name=barrow />

Mayr said of his own involvement with 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."<ref name=barrow />

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 sparrow]]s. Nice wrote to [[Joseph Grinnell]] in 1932, trying to get foreign literature reviewed in the ''Condor'': "Too many American ornithologists have despised the study of the living bird; the magazines and books that deal with the subject abound in careless statements, anthropomorphic interpretations, repetition of ancient errors, and sweeping conclusions from a pitiful array of facts.&nbsp;... in Europe the study of the living bird is taken seriously. We could learn a great deal from their writing." Mayr ensured that Nice could publish her two-volume ''Studies in the Life History of the Song Sparrow''. He found her a publisher, and her book was reviewed by [[Aldo Leopold]], Joseph Grinnell, and [[Jean Delacour]]. Nice dedicated her book to "My Friend Ernst Mayr."<ref name=barrow/>

Mayr joined the [[Faculty (teaching staff)|faculty]] of [[Harvard University]] in 1953, where he also served as director of the Museum of Comparative Zoology from 1961 to 1970. He retired in 1975 as [[emeritus]] professor of [[zoology]], showered with honors. Following his retirement, he went on to publish more than 200 articles, in a variety of journals—more than some reputable scientists publish in their entire careers; 14 of his 25 books were published after he was 65. 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. His wife, Margarete, died in 1990. He was survived by two daughters, five grandchildren and 10 great-grandchildren.<ref name="SNBC">{{cite news |title=Evolutionary theorist dies at 100 |date=2005-04-02 |work=MSNBC|url=http://www.msnbc.msn.com/id/6914624/ }}</ref>

The awards that Mayr received include the [[National Medal of Science]], the [[Balzan Prize]], the [[George Sarton Medal|Sarton Medal]] of the [[History of Science Society]], the [[International Prize for Biology]], the [[Loye and Alden Miller Research Award]], and the [[Lewis Thomas Prize|Lewis Thomas Prize for Writing about Science]]. In 1939 he was elected a [[Royal Australasian Ornithologists Union Fellows|Corresponding Member of the Royal Australasian Ornithologists Union]]. He was awarded the [[Linnean Society of London]]'s prestigious [[Darwin-Wallace Medal]] in 1958 and the [[Linnaean Society of New York]]'s inaugural [[Eisenmann Medal]] in 1983. For his work, ''Animal Species and Evolution'', he was awarded the [[Daniel Giraud Elliot Medal]] from the [[United States National Academy of Sciences|National Academy of Sciences]] in 1967.<ref name=Elliot>{{cite web|title=Daniel Giraud Elliot Medal|url=http://www.nasonline.org/site/PageServer?pagename=AWARDS_elliot|publisher=National Academy of Sciences|accessdate=15 February 2011}}</ref> In 1995 he received the [[Benjamin Franklin Medal for Distinguished Achievement in the Sciences]] of the [[American Philosophical Society]].<ref name="franklinscience_recipients">{{cite web|url=http://www.amphilsoc.org/prizes/franklinscience |title=Benjamin Franklin Medal for Distinguished Achievement in the Sciences Recipients |publisher=[[American Philosophical Society]] |accessdate={{Start date|2011|11|27}}}}</ref>
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 is no Nobel Prize for biology.) Mayr did win a 1999 [[Crafoord Prize]]. It honors basic research in fields that do not qualify for Nobel Prizes and is administered by the same organization as the Nobel Prize.

Mayr was co-author of six global reviews of [[bird species new to science]] (listed below).

Mayr was an atheist, stating "there is nothing that supports the idea of a personal God".<ref>{{cite journal | last1 = Shermer | first1 = M. | last2 = Sulloway | first2 = F.J. | year = 2000 | title = The grand old man of evolution | url = http://www.stephenjaygould.org/library/mayr_interview.html | journal = [[Skeptic (U.S. magazine)|Skeptic]] | volume = 8 | issue = 1| pages = 76–82 }}</ref>

==Mayr's ideas==
As a traditionally trained biologist with little [[mathematics|mathematical]] experience, Mayr was often highly critical of early mathematical approaches to evolution such as those of [[J.B.S. Haldane]], famously calling in 1959 such approaches "beanbag genetics". He maintained that factors such as [[reproductive isolation]] had to be taken into account. In a similar fashion, Mayr was also quite critical of [[molecular evolution]]ary studies such as those of [[Carl Woese]].

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 isolated genes only. Current molecular studies in evolution and speciation indicate that although [[allopatric speciation]] seems to be the norm in groups (such as in many invertebrates—especially in the insects), there are numerous cases of [[sympatric speciation]] in groups with greater mobility (such as the birds).

After articulating the [[biological species concept]] in 1942, Mayr played a central role in the [[Species Problem|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 one known to sharply critique science on the edge. As a notable recent example, he criticized the search for aliens as conducted by fellow Harvard professor [[Paul Horowitz]] as being a waste of university and student resources, for its inability to address and answer a scientific question.

Mayr rejected the idea of a [[gene-centered view of evolution]] and starkly but politely criticized [[Richard Dawkins]]' ideas:

{{quotation|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 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.<ref name = "ddrjeu">[http://www.edge.org/3rd_culture/mayr/mayr_print.html Edge: What Evolution Is<!-- Bot generated title -->]</ref>}}

Mayr insisted throughout his career that the [[gene]] as the target of selection cannot and should not be considered a valid idea in modern [[evolutionary thought]].

<blockquote>''The idea that a few people have about the gene being the target of selection is completely impractical; 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|Dobzhanksy]], 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 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''.<ref name = "ddrjeu"/></blockquote>

===Research on pigmentation===

According to Mayr (1970), dark skin coloring is most often correlated with humid areas where vegetation is abundant and tends to produce dark shadows. This is not a coincidence because research by R.B. Cowles (1959, 1967) has shown that humans often follow the same rules of protective coloration as other mammals. So while the black panther of the jungle, by virtue of his ability to blend in with the dark shadows cast by the many trees and plants, is better able to stalk his prey, dark coloration likewise allowed ancestral hunter-gatherers of the forest to both hide from predators and hunt down their next meal. 

{{Quote|"Even the zebra and giraffe, conspicuous as they may appear in isolation, have markings which skilfully conceal them against a background of trees, foilage and shadows." - Biological Perspectives on Human Pigmentation, Ashley H. Robins, Cambridge University Press, 2005, p. 68}}

===Species===

: ''"I was all alone with a very primitive tribe of mountain Papuans, who were excellent hunters. I sent them out every morning with their guns, and for every specimen they brought back I asked, “What do you call this one?” I recorded the scientific name in one column, and the native one in another. Finally, when I had everything in the area, and when I had compared the list of scientific names and the list of native names, there were 137 native names for 138 species. There were just two little greenish bush warblers for which they had a single name."'' – Mayr, Ernst. (1955). “The species as a systematic and as a biological problem”. Proceedings of the 16th Annual Biological Colloquium. Oregon State College. Corvallis.
==Awards and honours==
Mayr held around 20 regular and honorary academic degrees, including an honorary doctorate from the University of Konstanz (philosophy). In 1954 he was elected to the American Academy of Arts and Sciences and the National Academy of Sciences (NAS). He was member and honorary member of countless academic societies.
