quote:When Nick Patterson of MIT and his colleagues at the Broad Institute compared the genes of humans and chimps, they found that one of the chromosomes -- the female sex chromosome X -- was 1.2 million years younger than the others. It appeared the two species shared a common ancestor who gave them both their X chromosomes, and did so more recently than the ancestors who gave them all the other chromosomes.
The best explanation, the scientists think, is that ancient humans and chimps broke away from each other not once, but twice. The first time was more than 6.3 million years ago. The second time was at least a million years later.

Anyone who ever doubted we were closely related to monkeys never had to teach a Junior Sunday School class.

I have this awful feeling that I may be the only person who had this children's rhyme flash through my head when I saw this news item:
