Evolutionary theorists agree that there are local trends in evolution, such as increasing brain size in hominids, but these directional changes do not persist indefinitely, and trends in opposite directions also occur (Gould, 1997). Evolution causes organisms to adapt to their local environment; when the environment changes, the direction of ...

The idea of evolution by natural selection was proposed by Charles Darwin in 1859, but evolutionary biology, as an academic discipline in its own right, emerged during the period of the modern synthesis in the 1930s and 1940s. [19] It was not until the 1980s that many universities had departments of evolutionary biology.
According to Ernst Mayr, professor of zoology at Harvard University, Darwin's most distinct contributions to evolutionary biology and ecology are as follows: "The first is the non-constancy of species, or the modern conception of evolution itself. The second is the notion of branching evolution, implying the common descent of all species of ...
Systematics and the Origin of Species from the Viewpoint of a Zoologist is a book written by zoologist and evolutionary biologist Ernst Mayr, first published in 1942 by Columbia University Press. [1] The book became one of the canonical publications on the modern synthesis and is considered to be exemplary of the original expansion of ...
Pharmaceutical companies utilize biological evolution in their development of new products, and also use these medicines to combat evolving bacteria and viruses. [94] Because of the perceived value of evolution in applications, there have been some expressions of support for evolution on the part of corporations.

Darwin's first sketch of an evolutionary tree from his First Notebook on Transmutation of Species (1837). Charles Darwin became a naturalist at a point in the history of evolutionary thought when theories of Transmutation were being developed to explain discrepancies in the established faith based explanations of species.
