Mondo Knows Facts

Humans and chimpanzees share most of their DNA

The two species match at close to 99 percent of comparable DNA positions Genome comparisons show that humans and chimpanzees are more alike than either is to gorillas. The differences that matter are not only single letters but also how and when genes are switched on. The two lineages split roughly six to seven million years ago. It sits in Mondo's science collection, one of 200 facts that each trace back to the reference below.
