Mayr was an outspoken defender of the scientific method and was known to critique sharply science on the edge. As a notable example, in 1995, he criticized the Search for Extra-Terrestrial Intelligence (SETI), as conducted by fellow Harvard professor Paul Horowitz , as being a waste of university and student resources for its inability to ...
Ernst Mayer (24 June 1796 [1] – 21 January 1844) was a German sculptor in the classical style. He was a pupil of Antonio Isopi and worked for Leo von Klenze , mainly in Munich where in 1830 he became Professor of Sculpture at the Polytechnic, now the Technical University .
In the 1950s, Ernst Mayr entered the field of anthropology and, surveying a "bewildering diversity of names", decided to define only three species of Homo: "H. transvaalensis" (the australopithecines), H. erectus (including the Mauer mandible, and various putative African and Asian taxa) and Homo sapiens (including anything younger than H ...
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 ...
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.
The mechanisms of reproductive isolation have been classified in a number of ways. Zoologist Ernst Mayr classified the mechanisms of reproductive isolation in two broad categories: pre-zygotic for those that act before fertilization (or before mating in the case of animals) and post-zygotic for those that act after it.

Biologists, however, have not limited their application of the term neo-Darwinism to the historical synthesis. For example, Ernst Mayr wrote in 1984 that: The term neo-Darwinism for the synthetic theory [of the early 20th century] is sometimes considered wrong, because the term neo-Darwinism was coined by Romanes in 1895 as a designation of Weismann's theory.
They were able to produce statistical models of population genetics that included Darwin's concept of natural selection as the driving force of evolution. [44] Developments in genetics persuaded field naturalists such as Bernhard Rensch and Ernst Mayr to abandon neo-Lamarckian ideas about evolution in the early 1930s. [45]
