"If evolution is a product of changes in the physical and biological environment, and there are no changes in the physical and biological environment, then there will be no evolution," said J. William Schopf, a paleobiologist at UCLA.

He calls it the null hypothesis required of Darwin's equation.

I'm not sure if I buy it, personally, but it's really cool either way. It seems to me that regardless of changing environment, organisms ought to still select naturally the most favorable traits...but I'm certainly no biologist, and it looks like the data supports their conclusion regardless of my rhetoric.
