I just have to share a TV experience that I've just had! The last part of "The life of mammals", a TV serial by David Attenborough was about monkeys, apes and humans. 

It showed among other things a group of san hunters from the Kalahari desert hunting a Kudu. 5-6 men were chasing a herd of Kudu antilopes trying to separate a male with big horns because that one would be exhausted sooner than the others. When they had managed to do that only one of the men kept running after the kudu. Two legs are more efficient than four when running over large distances. The man was sweating which kept him cool but the kudu had to find shadow and rest to cool off which it could not do since it was being chased. The man also had water with him in a little rucksack.
After eight hours the kudu fell to the ground dying from exhaustion and the hunter ran a spear through the animal.
I've never before heard of hunting like this and I though it was fascinating. I'm thinking of everything that is said against meat eating like we have no fangs and no claws so we must have been vegetarians or fruitarians or perhaps scavengers. It was all guessing. What have all those archaeologists and sociologists and explorers been doing out there? Oh, I know - they've all been to full of wheaten buns to be able to leave the camp so they stayed there making things up.
Can you imagine - running for eight hours in the African desert?
