There are monkeys such as capuchins which are quadrupeds that make tools. They just sit on their haunches and do it. Mere cats can stand up and look over the grass and stand on things. So why bipedality happened? What good is it for? Well, it's certainly good for all these things, but it's certainly very bad in many other ways. Also, it's very disadvantageous if you break a leg.

Now, everyone's seen three-legged dogs running along quite happily. But, you know, a one-legged hominin, if you broke a leg, you'd be killed. You'd be eaten instantly by some animal. I mean, I broke an ankle in a trivial accident at home.

few years ago and i was only rehabilitated thanks to the national health service so i was carted off in an ambulance i will have the administration of surgeons and anesthetists and physiotherapists and a wheelchair alone from the red cross and the long-suffering mrs g to pull me to to push me around in it and a circumstance which definitely led although she denies it to her

going back to university to qualify as a nurse, specialising in people with learning disabilities, go figure. But without all these things, I would have died. So natural selection ensured that when hominins started to be bipedal, they had to get very good at it very quickly. Otherwise, so once they started to be bipedal, there was no way back.

And so that's why you get all these bipedal hominins around that time.

Yes, 2.5 million years ago or thereabouts was a big change in the Earth climate. It suddenly began to get much cooler than it had been and more seasonal. That's when in the north and far south and in mountain ranges, the ice ages, the sequences of ice ages began to take hold and become more serious. And the result of that was in the tropics,

The forest shrunk further, and something opened up this tropical grassland called the savannah, which opened up. And around that time, two new kinds of hominin appeared. One was called Paranthropus, which was a specialist vegetarian. Now, all hominins before that had been kind of scavengers, omnivores.
