His work contributed to the conceptual revolution that led to the modern evolutionary synthesis of Mendeliangenetics, systematics, and Darwinianevolution, and to the development of the biological species concept. 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 1. 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. Select up to three search categories and corresponding keywords.

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.

His father was a jurist District Prosecuting Attorney at Wrzburg4 but took an interest in natural history and took the children out on field trips. He learnt all the local birds in Wrzburg 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 1. Dresden Neustadt and completed his high school education there. In April 1. 92. 2, 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 1. 92. Mayr passed his high school examination Abitur and his mother rewarded him with a pair of binoculars. On 2. March 1. 92. Moritzburg, the Frauenteich, he spotted what he identified as a red crested pochard. The species had not been seen in Saxony since 1. Raimund Schelcher 1. 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 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 1. Mayr himself, took the medical curriculum to satisfy a family tradition but after only a year, he decided to leave medicine and enrolled at the Faculty of Biological Sciences. Mayr was endlessly interested in ornithology and chose Greifswald at the Baltic for my studies for no other reason than that. Although he ostensibly planned to become a physician, he was first and foremost an ornithologist. 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. In 1. Stresemann suggested that he give up his medical studies, in fact he should leave the faculty of medicine and enrol into the faculty of Biology and then join the Berlin Museum with the prospect of bird collecting trips to the tropics, on the condition that he completed his doctoral studies in 1. Mayr completed his doctorate in ornithology at the University of Berlin under Dr. Carl Zimmer, who was a full professor Ordentlicher Professor, on 2. June 1. 92. 6 at the age of 2. On 1 July he accepted the position offered to him at the museum for a monthly salary of 3. Reichsmark. 8At the International Zoological Congress at Budapest in 1. Mayr 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 2. 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 Detzners popular book Four Years Among the Cannibals in German Guinea from 1. 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 1. American Museum of Natural History, where he played the important role of brokering and acquiring the 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 1. 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. 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. Mayr encouraged his Linnaean Society seminar participants to take up a specific research project of their own. Under Mayrs influence one of them, Joseph Hickey, went on to write A Guide to Birdwatching 1. 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 1.
