The woolly mammoth is the ancient ancestor of elephants, which appeared in modern Siberia 450,000 years ago and disappeared from the face of the earth 4,000 years ago.

Its meat was part of the diet eaten by ancient humans, who used the skeleton and ivory of the uncle to build houses and weapons.

Scientists have long believed that humans are responsible for the extinction of mammoths. But the aforementioned team of scientists found another reason, which is the rapid change in the Earth’s climate.

Scientists have found that mammoths have become extinct due to food shortages caused by melting ice in the Arctic. SK Ferrelslav, a professor at St. John’s College in Cambridge University and director of the Center for Arctic Geogenetics at the University of Copenhagen, explained that rapid climate change is the cause of animal death. He said the melting of ice in the Arctic had led to the formation of high humidity, lakes, rivers and swamps, and the almost complete disappearance of plants eaten by mammoths.

Large animals cannot quickly adapt to bad food after changing the quality of their food.

An international team of scientists has studied the ancient ecological DNA of more than 1,500 specimens of plants and animals that are about 50,000 years old, according to the results of a study by scientists in the journal Nature. 535 different locations in the Arctic from ancient ice and ancient lakes.

According to scientists at the University of Petersburg, they revealed samples obtained from the Severnaya Gemlia archipelago and the Timir Peninsula.

Based on these models, the scientists created a map of the distribution of mammoths and showed the dynamics of the decline in their numbers. A thousand years ago, but some of them were able to live in some areas until the age of the Quaternary geography (4000 years ago), after which the species became completely extinct.
