Biology Quote by George C. Williams

“Universally accepted, microevolution has limits for what it can explain. These limits do not reach the center where the controversy lies - the Thesis…

— Jon Morrison

The major novelty of my theory was its claim that the most rapid evolutionary change does not occur in widespread, populous species, as claimed…

— Ernst Mayr

“He saw that there is a spectrum of variation between species that comes into being slowly, tiny change by tiny change. He realized that…

— Bill Nye

The essence of Darwinism lies in its claim that natural selection creates the fit. Variation is ubiquitous and random in direction. It supplies raw…

— Stephen Jay Gould

There is behavioral ecology, which looks closely at the difference different ecologies make to behavior and other features of animals and humans. There's evolutionary…

— Brian Boyd

“Only a minority of biologists today hold that the variation of evolution cannot be random. In this point the minority are on more solid…

— Lee Spetner

As a consequence, geneticists described evolution simply as a change in gene frequencies in populations, totally ignoring the fact that evolution consists of the…

— Ernst Mayr

Evolutionary biologists are not content merely to explain how variation occurs within limits, however. They aspire to answer a much broader question-which is how…

— Phillip E. Johnson

My theory of evolution is that Darwin was adopted.

— Steven Wright

In fact, nothing in science as a whole has been more firmly established by interwoven factual information, or more illuminating than the universal occurrence…

— E. O. Wilson

“Genetics might be adequate for explaining microevolution, but microevolutionary changes in gene frequency were not seen as able to turn a reptile into a…

— Scott F. Gilbert

“To understand Darwin's work, you have to distinguish between his theory of descent and his theory of natural selection. THe full name of the…
