The Roots of Humanity

I propose that Australopithecus is to be more accurately considered a chronogenus, similar to how Homo erectus is considered a chronospecies. I mean, Australopithecus already is paraphyletic because it excludes Homo, its descendant genus, and there are human species that display many primitive, australopithecine traits, and many australopithecine species that feature advanced, human traits. So much so in fact that the line between “human” and “protohuman” has been increasingly blurred over the years, to the point we’re having debates over whether something like H. habilis is truly a human or rather an australopithecine proto-human instead.

We know that stone tools were already in use by 3.3 Ma, and that we were already losing our body hair by 3.2 Ma (which surprise surprise indicates persistence hunting), and that australopithecine social structures would’ve been more similar to modern humans than chimps (australopithecines gave birth the hard, human way, rather than the easy chimp way), including that the males took part in raising the young, and that australopithecine couples were at the very least serially monogamous. We don’t know how complex they were, or how much more similar to modern human socials structures they were than to chimps, since so much time has passed between then and now, but we know at the very least the beginnings of everything thought of as “human,” from bipedality to marriage to technology (rather than simple tool use), had its roots in the australopithecines.

Of course, that’s not to mention the extremely early migrations out of Africa that lead to the H. floresiensis lineage, since recent phylogenetic analyses indicates the Hobbits of Flores were even more basal than H. habilis was, and the findings of stone tools in China dated to over two million years ago, and how the primitive species H. naledi was found to have lived as recently as 200kya, we now know the story of human evolution is a *lot* more complex than we once thought, indeed it’s apt, if somewhat crude, to call it what it is: a *clusterfuck*.
