I HAVE BEEN FORTUNATE to spend some of my life in Africa, the cradle of humanity. One of my most memorable experiences was visiting the Ngorongoro Crater, the Serengeti, and the Olduvai Gorge, which early human ancestors inhabited nearly two million years ago. There is an abundance of wild animals — lions, hyenas, elephants, water buffalo. Even the baboons are dangerous: a large male weighs nearly a hundred pounds and has enormous incisors. Nevertheless, they are all afraid of humans. If you are camping there and a big baboon tries to steal your food, all you have to do is raise your arm with a stone in your hand, and it will scurry away.
