The Cheetah's a Cheat, I'm a Chimp, Isn't It?

We've evolved, it goes back about 7 million years, so with our early hominid ancestors and hominids started going bipedals. That was the catalyst that sort of cascaded everything else. I work with chimps and gorillas mostly in the wild and across Africa,. They've got these wonderful feet with big toes that come out of the sides - just like our hands. It's interesting, isn't it, the modern human? You think of the shape of a modern human, our body planned. A great deal of that comes from this selection pressure to just run.
