Teams Work to Decipher Neanderthal DNA

Two separate teams have begun sequencing the genome of a Neanderthal. The DNA is extracted from fossilized bones. So far, only 1 million of the 3 billion DNA letters of the genome have been sequenced, but the authors say it proves the complete sequence is attainable.

Based on the latest DNA evidence, the authors suggest humans and Neanderthals went their separate ways between 375,000 and 500,000 years ago.
