The programming talent myth

Yes indeed, we're pretty well adapted to working in heat. Hence the sparse, fine hair (except on the head) and the profuse sweating. Presumably, our brains being large enough to realise we can clean animal skins and tie them up (using connective tissue of same animal, if nothing else) to make a waterbag we can carry allowed us to go even further down that evolutionary path.

We're amazing animals when it comes to endurance. Sad how so few humans exercise this ability anymore though. ;)
