  2. Significance

    Modern humans dispersed into Europe and replaced Neanderthals at least 40,000 years ago. However, the precise timing and climatic context of this dispersal are heavily debated. Therefore, a new project combining paleoenvironmental and archaeological fieldwork has been undertaken at Willendorf II (Austria), a key site for this time period. This project has concluded that modern humans producing Aurignacian stone tools occupied Central Europe about 43,500 years ago in a medium-cold steppe environment with some boreal trees along valleys. This discovery represents the oldest well-documented occurrence of behaviorally modern humans in Europe and demonstrates contemporaneity with Neanderthals in other parts of Europe, showing that behaviorally modern humans and Neanderthals shared this region longer than previously thought.

    Abstract

    The first settlement of Europe by modern humans is thought to have occurred between 50,000 and 40,000 calendar years ago (cal B.P.). In Europe, modern human remains of this time period are scarce and often are not associated with archaeology or originate from old excavations with no contextual information. Hence, the behavior of the first modern humans in Europe is still unknown. Aurignacian assemblages—demonstrably made by modern humans—are commonly used as proxies for the presence of fully behaviorally and anatomically modern humans. The site of Willendorf II (Austria) is well known for its Early Upper Paleolithic horizons, which are among the oldest in Europe. However, their age and attribution to the Aurignacian remain an issue of debate. Here, we show that archaeological horizon 3 (AH 3) consists of faunal remains and Early Aurignacian lithic artifacts. By using stratigraphic, paleoenvironmental, and chronological data, AH 3 is ascribed to the onset of Greenland Interstadial 11, around 43,500 cal B.P., and thus is older than any other Aurignacian assemblage. Furthermore, the AH 3 assemblage overlaps with the latest directly radiocarbon-dated Neanderthal remains, suggesting that Neanderthal and modern human presence overlapped in Europe for some millennia, possibly at rather close geographical range. Most importantly, for the first time to our knowledge, we have a high-resolution environmental context for an Early Aurignacian site in Central Europe, demonstrating an early appearance of behaviorally modern humans in a medium-cold steppe-type environment with some boreal trees along valleys around 43,500 cal B.P.

    • Excerpts:
    • Our evidence that Europeans today harbor ancestry that wasn’t present in the first farmers is important as it shows directly that there was a major movement of people into Europe after the advent of agriculture,” Reich said. “This motivates further ancient DNA work to try and figure out what archaeological cultures were responsible for bringing this ancestry.”


       In addition to the European findings, Lazaridis said the work also indicates the existence of a new “basal Eurasian” population, one that split from modern humans as they emerged from Africa, predating other early divergences, such as those that led to Australian aborigines, New Guineans, and other eastern peoples.

      Lazaridis said the period of approximately 4,500 years ago appears likely for the influx, because that is when new types of mitochondrial DNA appear in the genetic record. Reich added that there are hints from other disciplines, including linguistics, that point to migrations during that time span.
