Re:Was it rediscovered OR did it re-evolve? on Extinct Wildflower Found In California · · Score: 1That's pretty much exactly wrong. The fact is that fossil records show far more stability of species forms - over periods lasting millions of years - than change. So much so,, in fact, that it was a problem reconciling the fossil record with the classical notion of incremental evolution over time. That's why Stephen J. Gould and Niles Eldredge had to come up with the notion of Punctuated Equilibrium, in which long periods of statsis alternate with rapid speciation. Because evolution doesn't work that way. It's not unlikely that a new eriogonum species would evolve to fill a nche left by the extinction of another eriogonum, but the chances that it would closely resemble the old species - to the point where botanists had a hard time distinguishing the two - are infinitesimal. I say your time would be well-spent reading a basic text in evolution or plant biology.
