Neanderthals have long been the subject of scientific disputes, because there is still no clear answer to the question of the reasons for their disappearance. Recently, astronomers from Michigan University have proposed a new theory that binds the extinction of Neanderthals to shift the magnetic poles of the Earth about 41,000 years ago. As a result, the weakening of the magnetic field, according to their version, began to enter the planet more cosmic and ultraviolet radiation, which created adverse conditions for the survival of Neanderthals.
The study authors believe that Homo sapiens has been better adapted to such changes due to the use of clothing, caves, and ocher use to protect against solar radiation. However, scientists at Barcelona University categorically disagree with this version. They emphasize that Neanderthals also lived in caves and probably wore clothes, though they had no bone needles that could be sewn. Archaeological and genetic data indicate that people began to wear clothes at least 200,000 years ago. The Neanderthals may have used bone fragments to treat the skins and adapt them to the body. Also, researchers from Spain call into question the statement about the exclusive use of homo sapiens ocher to protect against ultraviolet light, as archaeological findings indicate that it was used by different groups of people. Instead, scientists believe that the extinction of Neanderthals is more associated with competition from the numerous Homo Sapiens, which had the advantage in hunting technologies, including the use of long -range weapons.
If a magnetic field decrease was a key cause of extinction, then increased mortality should be observed among Homo sapiens, but this is not. Therefore, today the relationship between the change of the Earth's magnetic field and the extinction of Neanderthals remains controversial.
