What is the third of "the three great discoveries" of modern science, according to Stephen Jay Gould?
Any citation from one of his books?
I know the first two are the vastness of space and the depth of time. Most likely the third has to do with evolution, but I'd like to know just what phrase he used to describe this -- something akin to the phrases used for the first two.
(I heard Gould start an invited address with that list at a National Science Teachers Association meeting in Boston many years ago. And he spoke at length about evolution vs. creationism, which is why I believe the third dealt with evolution, but I cannot recall now.)
