And there's another one in, there's some more in Ethiopia, Australopithecus, but there were some later ones and there were some slightly different ones. So there were quite a few of them. Now, whether there'll be a shakedown and they'll all be the same species or not, or whether there'll be more species, it's very hard to say.

But certainly, as much as anyone has looked between about five and two and a half million years ago, the Australopithecus model of hominin, which is basically a bipedal chimp, was the kind of hominin that existed on the Earth.

It's a big question. I mean, the question is, why did bipedality happen in the first place? It's a really unlikely form of locomotion.

And in my new book, which I wanted to call Demure Mindfulness the Taylor Swift Way, but the publishers insisted I called it The Decline and Fall of the Human Empire, I have a whole chapter on bipedality and why it was one of the worst things that could ever have happened to us.

Traditionally, explanations for bipedality, why we got up and stood on two legs, have been of a kind of after-the-fact reasoning. In other words, we got up on our hind legs to free our hands so we could make tools or carry babies or look over the long grass or show off our gender genitalia to prospective mate or any other idea you can come up with.

But these don't actually explain the existence of bipedality in the sense that bipedality is far more than getting up on your hind legs. Various animals can do this, but only for a short time because it's very tiring.

And to be bipedal, as a matter of course, requires a complete reengineering of the entire body, from the back of the skull, the curvature of the spine, the internal organs, the valves in the veins in our legs, how our feet are constructed. and all sorts of other things. And bipedality is unbelievably maladaptive.
