Neanderthals "Had Sex" With Modern Man
According to Professor Svante Paabo, director of genetics at the Max Planck Institute for Evolutionary Anthropology, Neanderthals and modern humans had sex across the species barrier. The professor has been using DNA retrieved from fossils to piece together the entire Neanderthal genome, and plans on publishing his findings soon. He recently told a conference that he was sure the two species had had sex, but still had questions as to how "productive" the relations had been. "What I'm really interested in is, did we have children back then and did those children contribute to our variation today?" he said. "I'm sure that they had sex, but did it give offspring that contributed to us? We will be able to answer quite rigorously with the new [Neanderthal genome] sequence." What remains a mystery is what Paleolithic brewery provided the catalyst for these stone age hook-ups.
Humans... so easy, a caveman can do them.
Developers, developers, developers...
If I have seen further it is by stealing the Intellectual Property of giants.
...and later went on to form the first government - which has been screwing modern man ever since.
"I'm sure that they had sex"
What evidence? The article says:
"We will be able to answer quite rigorously with the new [Neanderthal genome] sequence."
"Due to the length of time that has elapsed since Neanderthals became extinct, any trace of their DNA in modern humans could have been diluted below detectable levels. Paabo hopes to overcome this by scanning the Neanderthal genome for the genes of modern humans."
Okay, he hopes he will be able to overcome this technical limitation. So in other words, the statement that they had sex is just his personal opinion?

Helping ugly people have sex since 30,000 BCE!!!
The issue of introgression (gene flow from neanderthals to modern humans) is hugely important. It's a lot more important than the curiosity or oddity the Times article makes it out to be.
All the published studies looking for this introgression have been based on neanderthal mDNA. Since it doesn't undergo recombination, it's not a good marker, and the negative results so far are predictable and do not preclude gene flow. It'll be interesting to see Paabo's results. He's been working on getting nDNA data from neanderthal remains for a while now, and perhaps this is a hint that he's found some introgression.
Why it's important:
The small picture of why it's important is it would substantially redefine our family tree. We could refine our primate phylogeny.
The bigger, more hazy, and potentially earthshaking picture of why this could be important is that it doesn't take many viable pairings to get genes from one gene pool to another, and these genes could have been very important to our development. Modern humans and neanderthals were under many of the same environmental stresses but likely developed different adaptions to them. This includes behavior and cognition genes. As Stringer points out in the article, "in the last 10,000-15,000 years before they died out, around 30,000 years ago, Neanderthals were giving their dead complex burials and making tools and jewellery, such as pierced beads, like modern humans.” Proto-modern humans were smart. But neanderthals were also smart, potentially in different and complimentary ways. And perhaps it took a combination of proto-modern human and neanderthal genes to truly make the modern human mind. Our brains could be an example of 'hybrid vigor' on a grand scale.
So the big question mark is whether, given we can determine gene flow, if this hypothetical combination of proto-modern human and neanderthal cognitive adaptions could have led to the cultural explosion of ~30-50 thousand years ago. The biology is plausible and the timing's right. The data's still out, but it's coming in. Odder hypotheses have come true.
All we need to do now is to take that DNA, splice it back together with human 'junk' DNA and breed Neanderthals for the next great Disney theme park! Instead of being entertained by people walking around in giant suits pretending to be cartoon characters, it could be the greatest edutainment center in the world!!
But seriously. People have sex across interspecies barriers all the time; animal, vegetable, mineral, it doesn't matter. I doubt that Homo sapiens and Neanderthals looked at each other and said, Hey, I can't have sex with you, you're obviously a different species! Probably they thought to themselves, Two arms, two legs, looks about right, the bits are in the right places, why not?
Cave paintings or it didn't happen.
