your grandmother's a chimp!

No seriously -- your great-great-a-thousand-times-great-grandmother probably WAS a chimp, if the findings of this genetic research by scientists at MIT and Harvard are true. Mine probably was, too.

If species really were created in their current form by God/an Intelligent Designer/the Flying Spaghetti Monster/whatever, such research would be inconceivable because there would be no reason to expect humans and chimpanzees to share such a large portion of our genes -- let alone to have possibly had the ability in the far past to interbreed.

But I wouldn't recommend this trick now -- not all chimpanzees are as suave as Lancelot Link.
