Climate change has long led to the extinction of human species

In the past there were more than six races of humans. Over the years, however, only Homo Sapiens were able to survive.

Scientific research from the University of Naples has shown that climate change has led to the extinction of all human species except Homo Sapiens. They could not adapt to the increase or decrease of temperature. For these species the temperature became so extreme that they could not survive.

The results were obtained from a climate simulator that took into account temperature and weather for more than five million years.

These results cause great concern for today’s data where there is climate change which is naturally created by humans.
