Ancient periods of mutual depression temperature too dry out climate helped our species supervene upon Neanderthals inward Europe, a study suggests.

Scientists say ancient shifts inward climate helped our species supervene upon Neanderthals inward Europe. Researchers used information from this cave and roughly other to document ii lengthy mutual depression temperature too dry out periods.

"Whether they moved or died out, nosotros can't tell," said Michael Staubwasser of the University of Cologne inward Germany.
Neanderthals i time lived inward Europe too Asia but died out close 40,000 years ago, precisely a few chiliad years subsequently our species, Homo sapiens, arrived inward Europe. Scientists accept long debated what happened, too roughly accept blamed the alter inward climate. Other proposed explanations accept included epidemics too the sentiment that the newcomers edged out the Neanderthals for resources.
Staubwasser too colleagues reported their findings inward the Proceedings of the National Academy of Sciences. They drew on existing climate, archaeological too ecological information too added novel indicators of ancient climate from studies of ii caves inward Romania.
Their study highlighted ii mutual depression temperature too dry out periods. One began close 44,000 years agone too lasted close 1,000 years. The other began close 40,800 years agone too lasted half dozen centuries. The timing of those events matches the periods when artifacts from Neanderthals disappear too signs of H. sapiens appear inward sites inside the Danube River valley too inward France, they noted.
The climate shifts would accept replaced wood amongst shrub-filled grassland, too H. sapiens may accept been ameliorate adapted to that novel environs than the Neanderthals were, too thus they could movement inward subsequently Neanderthals disappeared, the researchers wrote.
Katerina Harvati, a Neanderthal goodness at the University of Tuebingen inward Deutschland who wasn't involved inward the study, said it's helpful to accept the novel climate information from southeastern Europe, a share that H. sapiens is sentiment to accept used to spread through the continent.
But she said it's unclear whether Neanderthals disappeared too H. sapiens appeared at the times the authors indicate, because the studies they refer rely on express testify too are sometimes opened upwards to dispute.
Chris Stringer of the Natural History Museum inward London said he sentiment the newspaper made a goodness example for an acquit upon of the climate shifts on Neanderthals, although he believes other factors were equally good at run inward their disappearance.
Rick Potts of the Smithsonian Institution called the study "a refreshing novel look" at the species replacement.
"As has been said before, our species didn't outsmart the Neanderthals," Potts said inward an email. "We only outsurvived them. The novel newspaper offers much to contemplate close how it occurred."
