One thing that Homo has that you don't have except in other predators such as dogs is a ligament that holds the back of the skull to the neck. So it keeps your head up even without effort. Another thing is if you have a neck and if you have a waist, you can keep running with your arms in contra rotation to your legs. In other words, your left arm moves with your right leg and vice versa.

And you can keep your neck pointed at where you're looking at, whether it's the finish line of the marathon or the antelope you are chasing. At the same time, humans became more hairless. I mean, humans have the same amount of hair, but it's much sparser. And in between, there are sweat glands that most other animals don't have. I mean, your dogs will pant if they're hot.

And animals such as antelopes and cheetahs and that sort of thing, they can run really fast for a short distance. And then they have to stop because they become exhausted and the heat catches up with them. But humans, humans can't sprint very well compared with other animals. But humans are much better than many animals at long distance running. It's the stamina part. Yeah, it's the stamina.

It's the endurance. It's the sweating. It's the hairlessness. It's the... the fact that the human cost of transport, in other words, human walking is extraordinarily efficient. This is why just walking about won't lose you many calories, because it's very, very efficient. Running is slightly less efficient, but humans can manage it mile after mile after mile after mile. So

Hunter-gatherers, when chasing down some antelope, will chase it for a bit, and then the antelope will stop, and everyone else will stop, and they'll recover. And then the antelope goes on a bit, and the humans chase it. But the humans are relentless, and eventually the antelope will just collapse from heat exhaustion. And this is what happens in real life.

And there's also a cooperative element, because as you find in many carnivals, like lions and hunting dogs, they kind of, different individuals head them off and ambush them, and one of them flushes it out while the other one jumps on it. This would have been true for Homo erectus as well.

So the human body shape that we associate with humans today came with Homo erectus, and it seems to have been associated with a capacity for long-distance running that the earlier hominins didn't have, or at least not as well.

Homo erectus is, as far as we know, the first hominin to spread out of Africa and spread all over Eurasia. There are tools from China that are over 2 million years old. There are remains of Homo erectus-like animals or hominins in Spain that are not quite as old. Now, Homo erectus would have no concept of a continent called Africa or that it was leaving it.
