Ernst Walter Mayr (/ ˈ m aɪər / MYRE, German: [ɛʁnst ˈmaɪɐ]; 5 July 1904 – 3 February 2005) [1] [2] was a German-American evolutionary biologist. He was also a renowned taxonomist , tropical explorer, ornithologist , philosopher of biology , and historian of science . [ 3 ]
This concept Ernst Mayr proposes here is now commonly referred to as the biological species concept. The biological species concept defines a species in terms of biological factors such as reproduction , taking into account ecology, geography, and life history; it remains an important and useful idea in biology, particularly for animal ...
Ernst Wilhelm Mayr (born 18 May 1950) is a German computer scientist and mathematician. He received the Gottfried Wilhelm Leibniz Prize in 1997 awarded for his contributions to theoretical computer science. [1] Mayr's research in computer science covers algorithms and complexity theory.
Darwin's theory of evolution is based on key facts and the inferences drawn from them, which biologist Ernst Mayr summarised as follows: [6] Every species is fertile enough that if all offspring survived to reproduce, the population would grow (fact). Despite periodic fluctuations, populations remain roughly the same size (fact).
Ernst Mayr proposed the widely used Biological Species Concept of reproductive isolation in 1942. Most modern textbooks make use of Ernst Mayr's 1942 definition, [63] [64] known as the biological species concept, as a basis for further discussion on the definition of species. It is also called a reproductive or isolation concept.
[14]: 427 Ernst Mayr championed the importance of physical, geographic separation of species populations, maintaining it to be of major importance to speciation. He originally proposed the three primary modes known today: geographic, semi-geographic, non-geographic; [21] corresponding to allopatric, parapatric, and sympatric respectively.
Ernst Mayr argued that geographic isolation was needed to provide sufficient reproductive isolation for new species to form. Ernst Mayr 's key contribution to the synthesis was Systematics and the Origin of Species , published in 1942. [ 73 ]
It was first fully outlined by Ernst Mayr in 1942, [1] using existing theoretical work by those such as Sewall Wright. [2] As a result of the loss of genetic variation, the new population may be distinctively different, both genotypically and phenotypically, from the parent population from which it is derived.
