Chimps, humans have striking differences in genes for smell, metabolism, hearing
January 14th, 2004
Nearly 99% alike in genetic makeup, chimpanzees and humans might be even more similar were it not for what researchers call "lifestyle" changes in the 6 million years that separate us from a common ancestor. Specifically, two key differences are how humans and chimps perceive smells and what we eat. A massive gene-comparison project involving two Cornell University scientists, and reported in Science, found these and many other differences in a search for evidence of accelerated evolution and positive selection in the genetic history of humans and chimps. In the most comprehensive comparison to date of the genetic differences between two...
