@RedPowerLady I only just heard of this today through this question and it separating the science from the hype might take a while, particularly since I really know nothing, so here is a summary that I am lazily pasting from the site above

As a primate, Ida is part of our own order, and able to throw light on our own ancestry. She comes from a highly significant age — the time when the anthropoids, our own subgroup of primates, were branching off from the prosimians.
Put everything together and Ida’s significance becomes clear: uniquely well preserved; from an era of key significance in primate evolution; and complete enough to help us rewrite our understanding of the primate family tree. Ida helps tell us who we really are and where we come from. We are all descended from Ida’s kind.
