Chimpanzee Fossils

As recently reported in Nature, fossil teeth of chimpanzees have been found. They date to about 545,000 years ago. Besides being some of the few chimp fossils found, they also demonstrate that chimps - in the past - were not confined to the same dense forest environments they are found in today. Who knows, maybe competitive exclusion is the reason why chimps and humans separated.
