Want to cook like a Neanderthal? Archaeologists are learning the secrets

Archaeologists seeking to learn more about how Neanderthals prepared and cooked their food conducted a series of hands-on experiments with small fowl using flint flakes for butchering. They found that the flint flakes were surprisingly effective for butchering the birds, according to their new paper published in the journal Frontiers in Environmental Archaeology. They also concluded that roasting the birds damages the bones to such an extent that it's unlikely they would be preserved in the archaeological record.

According to the authors, Neanderthals were able to thrive for over 200,000 years across a broad range of geographical regions, so naturally archaeologists are interested in how they sustained themselves. There has been research into their killing and hunting of large game. Neanderthals were expert hunters known to kill bears and other carnivores. A pair of lion fibula from the Middle Paleolithic found in eastern Iberia with cut marks indicates the lion was butchered, while other lion bones found in Southwestern France from the same period had cut marks indicative of skinning.

And as we reported just last year, researchers found evidence of what might be the earliest example of lion hunting yet known, based on a close forensic analysis of a cave lion skeleton showing evidence of injury by a wooden spear some 48,000 years ago.

Much of Neanderthal genetic diversity came from modern humans

The basic outline of the interactions between modern humans and Neanderthals is now well established. The two came in contact as modern humans began their major expansion out of Africa, which occurred roughly 60,000 years ago. Humans picked up some Neanderthal DNA through interbreeding, while the Neanderthal population, always fairly small, was swept away by the waves of new arrivals.

But there are some aspects of this big-picture view that don't entirely line up with the data. While it nicely explains the fact that Neanderthal sequences are far more common in non-African populations, it doesn't account for the fact that every African population we've looked at has some DNA that matches up with Neanderthal DNA.

A study published on Thursday argues that much of this match came about because an early modern human population also left Africa and interbred with Neanderthals. But in this case, the result was to introduce modern human DNA to the Neanderthal population. The study shows that this DNA accounts for a lot of Neanderthals' genetic diversity, suggesting that their population was even smaller than earlier estimates had suggested.
