A new study suggests that ancient periods of cold and dry climate led to Neanderthal(尼安德特人的) disappearance.Their disappearance was followed by the appearance of our species:Homo sapiens（modern human beings)．Neanderthals are a species of early humans that once lived in Europe and

Asia,which died out about 40，000 years ago.Homo sapiens arrived in Europe a few thousand years later。

Some scientists have blamed the change in climate.Others have explanations including the sudden spread of diseases and the idea that newcomers competed with the Neanderthals for resources。

Scientist Michael Staubwasser and his research team reported their findings.Their study focused on around two cold and dry periods。One began about 44，000 years ago and lasted about 1,000 years.The other began about 40,800 years ago and lasted about 600 years。The timing of those events matches the periods in which objects made by Neanderthals disappear。

During the two events，signs of Homo sapiens appear in areas within the Danube River Valley in central and Eastern Europe and in France，the team noted.

The changes in climate would，have turned forests into grassland filled with small plants.Homo sapiens may have been better adapted to that new environment than the Neanderthals were.So they may be able to move in after the Neanderthals disappeared，the researchers wrote。

Katerina Harvati is a Neanderthal expert who did not take part in the study。She said it is helpful to have the new climate data from southeastern Europe，which is an area that many researchers think Homo sapiens used to spread through the continent.

But Harvati said it is unclear whether Neanderthals disappeared and Homo sapiens appeared at the times the researchers claim.She said that is because the studies they base their findings on depend on limited evidence.

Rick Potts of the Smithsonian Institution called the study “a new look”at how one species took the other's place.

“As has been said before，our species were not cleverer than the Neanderthals，” Potts wrote。“We simply out-survived them。”
