Yup. That too.
And it was the distribution of species that got Darwin realizing how evolution works. He didn't have a fossil record or genetics, but only a large set of phenotypes, finches and such. If I remember right, the turtles got his attention first (but I could be wrong about that).
My understanding is that there's a growing number of animals and plants around Chernobyl. Animals that are a bit more resistant to radioactive pollution. Like lynx, Przewalki's horses, board, owls, etc. Plants and wildlife died out there at first, but now are moving back in... new mutations. Pfft. Evolution doesn't work? Yeah, right.
