altruism in chimpanzees

This article tells of how chimpanzees in the Tai forest found orphaned chimps and took them under their wing and took care of them as if they were their own. The chimps have nothing to gain, but gave themselves and went out of their way to take care of other chimps they found. The chimps adopted the chimps and acted as if they were one their own. Both male and female chimps showed this altruistic quality. This article supports the idea that altruism may come from evolution.
