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 ...
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 ...
Their paper built upon Ernst Mayr's model of geographic speciation, [3] I. M. Lerner's theories of developmental and genetic homeostasis, [4] and their own empirical research. [ 5 ] [ 6 ] Eldredge and Gould proposed that the degree of gradualism commonly attributed to Charles Darwin [ 7 ] is virtually nonexistent in the fossil record, and that ...
Founder effect: The original population (left) could give rise to different founder populations (right). In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population.
Mayr, on the basis of an understanding of genes and direct observations of evolutionary processes from field research, introduced the biological species concept, which defined a species as a group of interbreeding or potentially interbreeding populations that are reproductively isolated from all other populations.

"Tempo" encompasses "evolutionary rates … their acceleration and deceleration, the conditions of exceptionally slow or rapid evolutions, and phenomena suggestive of inertia and momentum," while "mode" embraces "the study of the way, manner, or pattern of evolution, a study in which tempo is a basic factor, but which embraces considerably more ...
