Well, I don't know how well this explains it, but I think it might be a contributing factor:
As man became carnivorous, it became necessary for him to develop different skills- he had to become a predator rather than a gatherer so needed to be far more mobile, and the range of his area increased significantly becuase you have to have lots of prey per predator. Where an herbivore eats a lot- due to the low caloric content- and has a long intestine to digest the fiber, the carnivore gets a big bang for his buck (or deer or wooly mammoth), but catching it is a lot harder. So--in the hot climes, he began to adapt, his stomach changing, his body type elongating, his nose developing, his hair decreasing.

. If chimpanzees were to evolve so as to acclimatize themselves to their surroundings

You must have missed my post:
Message 13874072

Evolution (Natural Selection) does NOT act upon groups, it acts upon individual organisms. Groups of animals do not change in mass. Some chimpanzees got by just fine living in the shrinking forest, with the same food, same temperature and rain, same preditors, and same amount of hair that they had before the ice age.

It was the chimpanzees that were a little different that got pushed out of the prime real estate and into the grass. These chimps were too tall to swing well, or too short to reach the branches, or bowlegged, or prone to disease. For the most part they died, had no little chimps, and their bodies were eaten by vultures.

Some were just a bit lucky, those that were too tall and had slightly short intestine tracks were able to survive on the fringe. They could stand and see over the grass to spot the approaching lion. They could rise up and scare the vultures eating the bowlegged chimps. It is these few who eventually completed the path to human. The chimps who were just right as chimps, had the right amount of hair and the correct shade of butt and swang well in the trees, they never left the forest, they didn't have to. They were fat and happy then and they are fat and happy now.
