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 ]
The Growth of Biological Thought (992 pages, Belknap Press, ISBN 0674364465) is a book written by Ernst Mayr, first published in 1982. It is subtitled Diversity, Evolution, and Inheritance, and is as much a book of philosophy and history as it is of biology. [1] It is a sweeping, academic study of the first 2,400 years of the science of biology ...
Systematics and the Origin of Species: On Ernst Mayr's 100th Anniversary was published by National Academies Press in 2005 in commemoration of this event. [10] The lectures published in this collection explore the main topics discussed in Ernst Mayr's Systematics and the Origin of Species from the Viewpoint of a Zoologist. [2]
Ernst Mayr wrote that a survey of evolutionary literature and biology textbooks showed that as late as 1930 the belief that natural selection was the most important factor in evolution was a minority viewpoint, with only a few population geneticists being strict selectionists.
Ernst Mayr defined a species as a population or group of populations whose members have the potential to interbreed naturally with one another to produce viable, fertile offspring. (The members of a species cannot produce viable, fertile offspring with members of other species). [ 69 ]
This model was popularized by Ernst Mayr in his 1954 paper "Change of genetic environment and evolution," [3] and his classic volume Animal Species and Evolution (1963). [29] Allopatric speciation suggests that species with large central populations are stabilized by their large volume and the process of gene flow.
Ernst Mayr considered orthogenesis effectively taboo in 1948. [ 6 ] By 1948, the evolutionary biologist Ernst Mayr , as editor of the journal Evolution , made the use of the term orthogenesis taboo: "It might be well to abstain from use of the word 'orthogenesis' .. since so many of the geneticists seem to be of the opinion that the use of the ...
For some time it was difficult to prove that sympatric speciation was possible, because it was impossible to observe it happening. [3] It was believed by many, and championed by Ernst Mayr, that the theory of evolution by natural selection could not explain how two species could emerge from one if the subspecies were able to interbreed.
