By the cold Darwinian logic of natural selection, evolution codifies happenstance into strategy.

— David Quammen

“Darwinists are right to say that selection favours the organisms that leave alive the most progeny, but vigorous growth takes place within a constrained…

We are moving from unconscious evolution through natural selection to conscious evolution by choice.

I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection.

— Charles Darwin

“The only way in which Darwin's data made sense was to suppose that species battled for survival, and that evolution came when one slight…
