Or the TNG episode 'The Chase' where it's revealed that humans, Klingons, Romulans, and Cardassians all came from a common ancestor.

I think in the case of humans, all from planet earth, it is trivial to go back and find an obvious common ancestor [1].

It is trivial to demonstrate the likely existence of a common ancestor. It’s far from trivial to find them.

don't forget Vulcans, and there are also half-Bajorans, right?
