Did Neanderthals Get It On With Humans?

As millions scrambled for gifts or grumbled bitterly in the final 48 hours leading up to Valentine's Day, BBC News reported that any Neanderthal wooing of Homo sapiens likely resulted in heartbreaking rejection. Yes, scientists from Germany's Max Planck Institute for Evolutionary Anthropology recently completed the first draft of the Neanderthal genome, mapping roughly 60 percent of nature's recipe for caveman, and discovered far less of us in them than expected.

Contrary to what horror movies and morning traffic may suggest, Neanderthals have been extinct for roughly 30,000 years. Yet they didn't just shamble off the stage and pass the torch to humans. They lived side by side with communities of Homo sapiens for thousands of years. We share between 99.5 and 99.9 percent of our DNA sequence with them, yet, according to a report by NewsDaily, we only appear to share one gene related to speech.

You might think this would have been a boon to prehistoric blind dates between the two species. Imagine the lengthy discussions about the latest cave painting at the local mammoth roast. Scientists have long speculated that we may have inherited some of our DNA through the ensuing interbreeding. Yet, when researchers compared common variations in the microcephalin-1 gene in humans with the Neanderthal genome, they found only ancestors of the modern human version.

Currently, researches believe that any interbreeding between the two species had only a limited impact on the human gene pool -- if that. While a few Neanderthal Don Juans may have managed to score, most never made it past first base.

Will future cloning techniques give Neanderthals a shot at hooking up in the age of dance clubs and MySpace? Only time will tell.
