Scientists found why old people use yellow 02:12

Old people can use it not only for decoration, but also as protection against increased ultraviolet radiation during a geomagnetic failure 41 thousand years ago. This conclusion was reached by scientists of the University of Michigan, who published a study in the magazine. Science progress (Sa).

The Lashamphage has weakened the magnetic field of the Earth 10 times, which led to an increase in the level of UV rays. In the most affected areas of radiation (Europe, Africa, Australia), the use of yellow became more frequent, a rock picture emerged and the clothes were complex. Researchers suggest that the pigment serves as a sunscreen analogue.

The authors of the study said, “The coincidence of the spread of Sarch with high UV radiation periods is too right to be random. This may be an important harmony for survival,” he said.

Before that, an international investigative team of Algarve University (Portugal) and the University of Vienna (Austria) discovered The last glacier is the unique evidence of the use of fire by old people in the coldest period of the maximum (26,500-19,000 years ago).
