A Silent Gene Theory of Evolution
Collins studied biology at Sussex University, where his tutor was the leading theoretical biologist John Maynard Smith. In 1975 Collins voiced to Maynard Smith the view that natural selection could not drive evolution because it always acted to reduce variation in favour of an optimum type for any environment, whereas the central story of evolution was that of increasing variation and complexity. Collins quoted Darwin in The Origin of Species ("... unless profitable variations do occur, natural selection can do nothing."), and argued that if variation must always occur before natural selection can act, then variation, and not natural selection, drives evolution. He asked Maynard Smith whether he could search for a "strong" theory of variation. Maynard Smith warned Collins that he could not support his efforts to pursue a rival theory to the theory that natural selection drives evolution. Collins replied that he thought the object of science was to question and examine everything, including hallowed theories such as the theory of natural selection. Maynard Smith asserted that, on the contrary, the strength of science was its capacity to agree on certain principles, and act collectively to pursue agreed aims. This difference of view with his tutor made Collins give up his scientific career and pursue other interests instead.

Famous quotes containing the words silent, theory and/or evolution:
“Duns at his lordship’s gate began to meet;
And brickdust Moll had screamed through half the street.
The turnkey now his flock returning sees,
Duly let out a-nights to steal for fees:
The watchful bailiffs take their silent stands,
And schoolboys lag with satchels in their hands.”
—Jonathan Swift (1667–1745)
“The theory [before the twentieth century] ... was that all the jobs in the world belonged by right to men, and that only men were by nature entitled to wages. If a woman earned money, outside domestic service, it was because some misfortune had deprived her of masculine protection.”
—Rheta Childe Dorr (1866–1948)
“As a natural process, of the same character as the development of a tree from its seed, or of a fowl from its egg, evolution excludes creation and all other kinds of supernatural intervention.”
—Thomas Henry Huxley (1825–95)
