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]
Darwin's work established evolutionary descent with modification as the dominant scientific explanation of natural diversification. [16] In 1871, he examined human evolution and sexual selection in The Descent of Man, and Selection in Relation to Sex, followed by The Expression of the Emotions in Man and Animals (1872).
A distinction can be made between botanical science in a pure sense, as the study of plants themselves, and botany as applied science, which studies the human use of plants. Early natural history divided pure botany into three main streams morphology - classification , anatomy and physiology – that is, external form, internal structure, and ...
The evolutionary biologist Stephen Jay Gould revived earlier ideas of heterochrony, alterations in the relative rates of developmental processes over the course of evolution, to account for the generation of novel forms, and, with the evolutionary biologist Richard Lewontin, wrote an influential paper in 1979 suggesting that a change in one ...
He published a report on his work with hawkweed, [53] a group of plants of great interest to scientists at the time because of their diversity. However, the results of Mendel's inheritance study in hawkweeds were unlike those for peas; the first generation was very variable, and many of their offspring were identical to the maternal parent.
Pinker accuses Gould, Lewontin, and other opponents of evolutionary psychology of being "radical scientists", whose stance on human nature is influenced by politics rather than science. [106] Gould stated that he made "no attribution of motive in Wilson's or anyone else's case" but cautioned that all human beings are influenced, especially ...
The simplest definition of "paleontology" is "the study of ancient life". [5] The field seeks information about several aspects of past organisms: "their identity and origin, their environment and evolution, and what they can tell us about the Earth's organic and inorganic past".
