Neanderthals are an extinct group of humans who lived between about 30,000 and 130,000 years ago. Despite their reputation as bone-headed dummies, Neanderthals were likely as advanced as modern humans in areas such as tool-making, though they were probably less socially adept. (from this article)The whole article suggests to me that Neanderthals would turn up at H Sapiens Sapiens parties, clutching a bag of over-ripe, intoxicating avocados, smiling hopefully, and saying that "I'm a friend of Simian's". Then hanging around, hoping to get lucky when all the more attractive H Saps have paired up.
I have visions of some H Sap Sap lass waking up, clutching her head, squinting over at the other side of the bear skins strewn across the cave floor, and realising to her horror that, in the dim light and after too much fermented yoghurt, she's scored with a Neanderthal. Swearing that he hadn't looked that hairy, or had quite such a big jaw, during that smoochy last dance.
Then, in the 2 minutes before she goes off to find a sabre-tooth tiger to loose in the cave, being treated to his explanations as to why God doesn't exist, and why it will be important for programming languages to support recursion. Sure, we were gonna need those genes later, when the Internet was invented. But what a price it was bought at.
