One thing I thought was pretty neat about the aardvark is that it burrows.  It’ll make a bunch of little burrows and then a main one for breeding.  It sort of makes sense that it survived so long, since it can hide underground and feeds off things that also hide in the ground/in trees and such.

There are a lot of birds that are living fossils too.  It kind of makes sense with that whole dinosaurs are ancestors of birds theory.
