I think there will be some un mutated or un evolved fauna and flora from thousands of years ago, as the ones A on the surface and cave would have to adapt, so posobly maybe the good ol' peepers from 1,000 years ago or at least what they looked like before they adapted to the carar and changing conditions on the surface.
