History employs evolution to structure biological events in time.

Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists-whether through design or stupidity, I do not know-as admitting that the fossil record includes no transitional forms. Transitional forms are generally lacking at the species level, but they are abundant between larger groups.

A man does not attain the status of Galileo merely because he is persecuted; he must also be right.

All evolutionary biologists know that variation itself is nature's only irreducible essence... I had to place myself amidst the variation.

Odd arrangements and funny solutions are the proof of evolution - paths that a sensible God would never tread but that a natural process, constrained by history, follows perforce.

The invalid assumption that correlation implies cause is probably among the two or three most serious and common errors of human reasoning.

Science can't tell us what our life means ethically. It can't tell us what we are meant to do as moral creatures. But, insofar as science can understand what we're made of, and what we're related to, the Darwinian revolution completely revised our ideas about who we are and what we're related to and how long we've been here and why we're on this Earth.
