WASHINGTON (AP) -- Chimpanzees are more closely related to people than to gorillas or monkeys and probably should be included in the human branch of the family tree, a research team says.
Currently, humans are alone in the genus Homo. But Goodman argues, "We humans appear as only slightly remodeled chimpanzee-like apes." He says humans and chimps share 99.4 percent of their DNA, the molecule that codes for life.
