In a significant advance, the researchers mapped most of the Neanderthal genome—the first time that the heredity of such an ancient human species has been reliably reconstructed. The researchers, able for the first time to compare the relatively complete genetic coding of modern and prehistoric human species, found the Neanderthal legacy accounts for up to 4% of the human genome among people in much of the world today.What a fascinating story. I love these sorts of discoveries. It's exciting. So does this mean we all have to reread The Clan of the Cave Bear? Pleeeeeease don't make me!
