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 ...
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 ...
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.
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.
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.
Harvard evolutionary biologist Ernst Mayr (1961) [8] suggested that there are two fundamentally different types of causation in biology, ‘ultimate’ and ‘proximate’. Ultimate causes (e.g. natural selection ) were seen as (i) providing historical accounts for the existence of an organism's features, and (ii) explaining the function or ...
The concept of teleonomy was largely developed by Mayr and Pittendrigh to separate biological evolution from teleology. Pittendrigh's purpose was to enable biologists who had become overly cautious about goal-oriented language to have a way of discussing the goals and orientations of an organism's behaviors without inadvertently invoking teleology.
