(urth) Dollo's Law...

[DAVID STOCKHOFF]

Like most of these Laws turn out to be.

"... In 2003, scientists showed that some species of insects have gained, lost and regained wings over millions of years."

That's a good example of a common-sense reversible adaptation. If humans experienced million-year floods every million years, we might evolve, devolve, and revolve webbed fingers and toes---because the original structure from which the webs were derived are still going to be around. Evolution uses the tools at hand. Tress have used and re-used the same basic leaf shapes for millions of years. 

I have forgotten the trait that brought up Dollo's Law---mind projection? mimicry? opposable thumbs?
