> Most things don't drift very fast at all. Most species in an old ecosystem could have evolved more than a million years ago and had little change since then.

No, that is the myth of the living fossil. It baffles me how you can deny this. What you are describing is an ecosystem composed entirely of living fossils. Living fossils don't exist.

It is not in fact possible for a species to have evolved more than a million years ago and had little change since then.

> I mean you couldn't tell the difference, other than it being a different tree. If you had a bunch of trees from 100,000 years ago and a bunch from today, you would not be able to sort them.

This might or might not be true, but it's pretty likely. If you give me a year to do the job, though, I'll be able to sort them.
