The frequently cited 99% similarity between human and chimp DNA overlooks key differences in the genomes.

NEW YORK — What makes us human? In a step toward finding biological answers, scientists have deciphered the DNA of the chimpanzee, our closest living relative, and made comprehensive comparisons to ...

Scientists believe they may have found a narrow slice of DNA that separates us from chimpanzees. Current research holds that humans and chimps split on the evolutionary tree about 7 million years ago.

On the genetic level, we're not all that different from chimps. But those small differences in dna can have massive effects.
