As part of the SUCESS project, scientists analyzed pollen from palaeoser kernels and minerals collected from ancient stalactites. In fact, they are climate time machines. Researchers deciphered what the environment was when they formed. The data refuted the leading theory of the extinction of Neanderthals.
Neadertalians lived in an era of middle and late playstone, about 400,000 to 400,000 years ago, and settled in Eurasia, their footprints in the north, up to modern Belgium, and in the south, the Mediterranean and South-West Asia.
For more than 350,000 years, Neanderthals settled in Europe and Asia until, as a result of a sudden change, they disappeared some 400,000 years ago, and around the same time, an anatomically modern person Homo sapiens appeared in Africa.
They were not the only hominid species on the planet at the time, but other archaic human groups, such as Homo floresiensis and the Denisans, also lived on Earth.
There are a number of competing theories that explain why the Neanderthals have disappeared. For example, this may have been influenced by the aggression of the developed Homo sapiens, by possible competition over resources, or even by the non-Anderthals disappearing because of the sensibility of the human being. Some human populations that live today in Europe and Asia differ by 3% of Neanderthal DNA.
Some scientists also argue that climate change may have led the Neanderthals to extinction, although it may have been true for other regions, but in Italy it was quite different, said the lead author of the new study, Professor Stefano Benazzi of the University of Bologna in Italy, who is an anthropologist who leads the SUCESS project on early migration of Homo sapiens in Italy.
In contrast to the analysis of ice cores from Greenland, the experts found no evidence of catastrophic climate change in Italy. It is unlikely that it destroyed the Neanderthals.
