The researchers discovered that the colder periods lived temporally over time, with the disappearance of the Neanderthals in different parts of the continent and the emergence of our current Homo sapiens.
Michael Staubwasser of the University of Cologne says, “We can not say it exactly if we move or kill another time.”
Neanderthals once lived in Europe and Asia, but it was consumed about 40,000 years ago. Only a few thousand years after that, Homo sapiens reached Europe. Researchers are trying to find out exactly what happened, and some researchers have pointed to climate change as a reason. Other proposed statements include outbreaks or ideas that newcomers have taken away from the food sources of Neanderthals.
In a new study they published, Staubwasser and his team discussed current climate, archaeological and ecological data and added new indicators of the old climate from two cave studies in Romania.
The research was focused on two climatic periods known as cold and dry. One was a period that started 44,000 years ago and lasted about 1,000 years. The second one, started 40,800 years ago, lasted for six hundred years.
The timing of these events coincided with the period when the works belonging to the Neanderthals remained in the middle and the signs of Homo sapiens appeared in the Danube Valley and in the regions of France.
Climate change must have changed the forests into meadows, and Homo sapiens should have been better adapted to the new neighborhood than the Neanderthals. So when the Neanderthals disappeared from the middle, they could move forward.
Neanderthals expert Katerina Harvati, who has not participated in the research from Tubingen University, says that Homo sapiens’ South East Europe, a region thought to be spreading along the continent, is very beneficial to have new climate data.
However, Harvati adds that it is unclear when the Neanderthals disappeared and when Homo sapiens emerged, at the time specified by the authors, because the work done was based on limited evidence and was open to disagreement from time to time.
Chris Stringer of the London Natural History Museum believes that while this research does not think climate change is a good example of the impact on Neanderthals, other factors also work in their disappearance.
Rick Potts of the Smithsonian Institute says this research brings a whole new perspective on the way the species change.
“As we have already seen, our class was not as intelligent as the Neanderthals. In a simple way we were more resistant to them. The new research offers a lot to think about how it happened. “
