Get gnashing Ken - teeth older than universe

Or so your Sidney Morning Herald implies...
Ancient Chinese teeth could rewrite human history
Washington: A set of 47 human teeth have been dated as at least 80,000 years old -- perhaps even older, changing scientists ideas of ancient migration. Most researchers believe humans only left Africa for the first time around 60,000 years ago. And even then, they were thought to trek to Europe first, not Asia.

The teeth, described in a paper published Wednesday in Nature, were found in a cave in China's Hunan province, and bear a close resemblance to those seen in modern humans. The researchers believe they're undoubtedly those of Homo sapiens.

"This is stunning, it's major league," Michael Petraglia, an archaeologist at the University of Oxford who was not involved in the research, told Nature. "It's one of the most important finds coming out of Asia in the last decade."

The researchers believe this may be a sign that humans were ready to leave the nest long before they trekked into Europe. It's possible that Neanderthals, who were in Europe at the time the owners of these teeth were in China, were in the way of a westward migration.

"The coincidence between the arrival of Homo sapiens to Europe and the Neanderthal extinction has often been interpreted as evidence of the superiority of modern humans," co-author Maria Martinon-Torres of the National Centre on Human Evolution in Spain told Discovery News. "However, we now wonder that if modern humans were already present in southern China more than 80,000 years ago, why were they not capable of entering Europe until 45,000 years ago? Maybe because Neanderthals were there, it was not easy to take over 'their' land."

Indeed, recent research on Neanderthals has suggested that they were much more formidable opponents than we once gave them credit for. Evidence indicates that they were intelligent enough to make art and jewellery, and may have culturally been quite similar to humans living at the same time. In a commentary article for Nature, the University of Exeter's Robin Dennell (who wasn't involved in the study) suggests that the warmer climate of Asia might have made it a more attractive destination for early settlers.

To better understand how these humans arrived and what they were doing there, the researchers will have to confirm their dating, which other researchers have suggested is compelling but not definitive. The teeth were found without any other signs of human life. There are no tools to indicate a settlement had been made in the cave. In all likelihood, the researchers say, these remains were simply dragged into the cave by predators that lived there.

In any case, it's unlikely that the teeth came from ancestors of modern Asians, as DNA testing suggests that those groups stem from humans who came to Asia by way of Europe, picking up some Neanderthal DNA along the way.

Two new things we've learned today:
1) "Ham's Teeth" are even older than I thought
2) Christian Scientists probably aren't YECs
Can 100,000-year-old teeth change human history?
