Climatologists Centre for physics of the climate in South Korea with the help of a supercomputer solved the mystery of the extinction of the Neanderthals. Contrary to the previous view, their disappearance 50-35 thousand years ago was not caused by neither climate change nor interbreeding with humans of the modern type. The real reason was competition with modern humans type. Article researchers published in the journal Quaternary Science Reviews.
Scientists have used a supercomputer IBS Aleph to create realistic models of the migration of Neanderthal and modern human type, their competition and interbreeding amid a changing in the time of climate. A series of mathematical equations describing the competition of both species for food resources under conditions of changing temperature, precipitation and vegetation. It turned out that extinction could occur only in case, if Homo sapiens had a significant advantage in the production of food. For example, they were able to use effective methods of hunting, to have a high resistance to pathogens or to be much more prolific.
Neanderthals lived in Eurasia in the last 300 thousand years, adapting to the harsh conditions and sudden climatic changes that have been even more dramatic than those that occurred during the disappearance of ancient people.
At the moment scientists are going to improve the mathematical model to include the interaction with megafauna, that is, populations of large animals, and more realistic climatic factors.
