Neanderthals More Advanced Than Previously Thought: They Innovated, Adapted Like Modern Humans, Research Shows

ScienceDaily (Sep. 21, 2010) — For decades scientists believed Neanderthals developed `modern' tools and ornaments solely through contact with Homo sapiens, but new research from the University of Colorado Denver now shows these sturdy ancients could adapt, innovate and evolve technology on their own.

The findings by anthropologist Julien Riel-Salvatore challenge a half-century of conventional wisdom maintaining that Neanderthals were thick-skulled, primitive `cavemen' overrun and outcompeted by more advanced modern humans arriving in Europe from Africa.

"Basically, I am rehabilitating Neanderthals," said Riel-Salvatore, assistant professor of anthropology at UC Denver. "They were far more resourceful than we have given them credit for."

His research, to be published in December's Journal of Archaeological Method and Theory, was based on seven years of studying Neanderthal sites throughout Italy, with special focus on the vanished Uluzzian culture.

About 42,000 years ago, the Aurignacian culture, attributed to modern Homo sapiens, appeared in northern Italy while central Italy continued to be occupied by Neanderthals of the Mousterian culture which had been around for at least 100,000 years. At this time a new culture arose in the south, one also thought to be created by Neanderthals. They were the Uluzzian and they were very different.

This paper presents an overview of the Middle–Upper Paleolithic transition in Italy in light of recent research on the Uluzzian technocomplex and on the paleoecological context of the transition. Drawing on the realization that human niche construction can be documented in the pre-agricultural archaeological record, niche construction theory is used as a conceptual framework to tie together facets of the behavioral, biological, and ecological dimensions of the transition interval into formal models of their interaction over time and in diverse contexts. Ultimately, this effort shows how foragers of the transitional interval in the Italian peninsula were active agents in shaping their evolutionary history, with consequences of some adaptive systems being felt only much later and directing the forces responsible for the ultimate disappearance of the Mousterian and Uluzzian technocomplexes in favor of the proto-Aurignacian industry, the exact nature of which clearly appears to vary on a regional level.
