Bones from French cave show Neanderthals, Cro-Magnon hunted same prey

A 50,000-year record of mammals consumed by early humans in southwestern France indicates there was no major difference in the prey hunted by Neanderthal and Cro-Magnon, according to a new study.

The paper, published in the online Journal of Archaeological Science, counters the idea proposed by some scientists that Cro-Magnon, who were physically similar to modern man, supplanted Neanderthals because they were more skilled hunters as a result of some evolutionary physical or mental advantage.

'This study suggests Cro-Magnon were not superior in getting food from the landscape,' said lead author Donald Grayson, a University of Washington professor of archaeology. 'We could detect no difference in diet, the animals they were hunting and the way they were hunting across this period of time, aside from those caused by climate change.

'So the takeover by Cro-Magnon does not seem to be related to hunting capability. There is no significant difference in large mammal use from Neanderthals to Cro-Magnon in this part of the world. The idea that Neanderthals were big, dumb brutes is hard for some people to drop. Cro-Magnon created the first cave art, but late Neanderthals made body ornaments, so the depth of cognitive difference between the two just is not clear.'

The study also resurrects a nearly 50-year-old theory first proposed by Finnish paleontologist Bj?Kurt that modern humans played a role in the extinction of giant cave bears in Europe. Cro-Magnon may have been the original 'apartment hunters' and displaced the bears by competing with them for the same caves the animals used for winter den sites.

Grayson and his colleague, Francoise Delpech, a French paleontologist at the Institut de Prehistoire et de Geologie du Quanternaire at the University of Bordeaux, examined the fossil record left in Grotte XVI, a cave above the Ceou River, near its confluence with the Dordogne River. The cave has a rich, dated archaeological sequence that extends from about 65,000 to about 12,000 years ago, spanning the time when Neanderthals flourished and died off and when Cro-Magnon moved into the region. Neanderthals disappeared from southwestern France around 35,000 years ago, although they survived longer in southern Spain and central Europe.

The researchers were most interested in the transition from the Middle to Upper Paleolithic, or Middle to Late Stone Age.

Neanderthals occupied Grotte XVI as far back as 65,000 years ago, perhaps longer. Between 40,000 and 35,000 years ago, people began making stone tools in France, including at Grotte XVI, that were more like those later fashioned by Cro-Magnon. However, human remains found with these tools at several sites, were Neanderthal, not Cro-Magnon. Similar tools but no human remains from this time period were found in Grotte XVI and people assumed to be Cro-Magnon did not occupy the cave until about 30,000 years ago.

The researchers examined more than 7,200 bones and teeth from large hoofed mammals that had been recovered from the cave. The animals ? ungulates such as reindeer, red deer, roe deer, horses and chamois were the most common prey ? were the mainstay of humans in this part of the world, according to Grayson.

He and Delpech found a remarkable dietary similarity over time. Throughout the 50,000-year record, each bone and tooth assemblage, regardless of the time period or the size of the sample involved, contained eight or nine species of ungulates, indicating that Neanderthals and Cro-Magnon both hunted a wide variety of game.

The only difference the researchers found was in the relative abundance of species, particularly reindeer, uncovered at the various levels in Grotte XVI. At the oldest dated level in the cave, reindeer remains accounted for 26 percent of the total. Red deer were the most common prey at this time, accounting for nearly 34 percent of the bones and teeth. However, as summer temperatures began to drop in Southwestern France, the reindeer numbers increased and became the prey of choice. By around 30,000 years ago, when Cro-Magnon moved into the region, reindeer accounted for 52 percent of the bones and teeth. And by around 12,500 years ago, during the last ice age, reindeer remains accounted for 94 percent of bones and teeth found in Grotte XVI.

Grayson and Delpech also looked at the cut marks left on bones to analyze how humans were butchering their food. They found little difference except, surprisingly, at the uppermost level, which corresponds to the last ice age.

'It is possible that because it was so cold, people were hard up for

might be a sign of food stress. However, if this had occurred earlier during Neanderthal times, people would have said this is a sure sign that Neanderthals did not have the fine hand-eye coordination to do fine butchering.'

In examining the Grotte XVI record, the researchers also found a sharp drop in the number of cave bears from Neanderthal to Cro-Magnon times.

'Cave bears and humans may have been competing for the same living

added that it is not clear if the decline and eventual extinction of the bears was driven by an increase in the number of humans or increased human residence times in caves, or both.

'If we can understand the extinction of any animal from the past, such as the cave bear, it gives us a piece of evidence showing the importance of habitat to animals. The cave bear is one of the icons of the late Pleistocene Epoch, similar to the saber tooth cats and mammoths in North America. If further study supports Kurt s argument, we finally may be in a position to confirm a human role in the extinction of a large Pleistocene mammal on a Northern Hemisphere continent.'

This line of argument makes no sense to me. How does the fact that Cro-Magnons and Neanderthals ate the same food items imply that the Cro-Magnons were not better at acquiring those items? It doesn't follow at all.

I suspect that they ate whatever was available. Why would it matter whether they were Neanderthals or Cro-Magnon?

Isn't the evidence pretty strong that Neanderthals were primarily carnivorous while Cro-Magnons were more balanced omnivores?

Ken

Neandertals were no more 'carnivorous' than any other group of people living in a cold climate where plant food wasn't available for long periods of time. There was *one* study from Vindija that seemed to indicate that they ate mostly meat, most of the time. And some people have interpreted this as 'extreme carnivory'. However, you have to remember that at the time the Neandertals were living, the area around Vindija wasn't exactly tropical. It gets pretty cold in the winter there, even now. Anne G

That's pretty much what the study in question seems to indicate. Anne G

Wow. They should hire me. It took me three seconds to come to that conclusion. I could have saved them a lot of money.

If one could show that Neanderthals and Cro-Magnons had significantly different diet I suppose one could draw conclusions from that. But showing that they had the same diet doesn't prove that they were equally effective hunters. Maybe they were, maybe they weren't; I don't see how it's evidence one way or the other.

John,

It seems to me that the effectiveness of hunting is best seen in the skeletal remains of the populations involved, as well as in the range of food sources used. Also, as the story noted, later food remains show that they were more efficiently used than earlier remains, which may be an indication of a reduction in hunting effectiveness.

If skeletal remains of the two populations over time appear to show similar patterns of nutrition, and nutritional deficits, this would be evidence (for populations who ate meat predominatly) of equal hunting _effectiveness_. Note that it says nothing about hunting _efficiency_. It is possible that one population attained the needed calories from meat in a shorter time than the other population. But this is a different question, and needs different evidence to evaluate. For this last, changes in tools and tool-making techniques, along with an analysis of group size and numbers of groups, and change in group size and/or numbers over time, could be useful.

If the range of animal foods used by the two populations were similar, and varied similarly over time, including showing similar changes in relative abundance of prey animals used, then similar hunting _effectiveness_ is clearly shown (always assuming that the human skeletal and other evidence supports similar nutrition over the same time).

If, on the other hand, one population was subsisting mainly on large animals, and the other population was using a broader range of animal sizes, then one could postulate that the second population was likely to be better able to adapt to sudden shifts in prey animal availability, and therefore be able to maintain hunting effectiveness over a longer period of time. That the record discussed in the article doesn't show this pattern indicates to me that the authors of the article were correct wrt hunting effectiveness.
