The researchers discovered that the last attempt of survival for black-haired mammoths in Siberia before the extinction was not of the native elephants, but rather giants of American origin. Black-haired mammoths have dominated the Earth for more than half a million years, from Europe and Asia to North America. This ice age giant disappeared from Siberia 9,000 years ago, although mammoths survived on the Wrangel island of the Arctic Ocean until about 3,700 years ago.

Other skeletons were found including a 5 meter long tusks, the researchers said it was the largest tusks discovered in the world. (Image: Evangelia Tsoukala / Thessalonki University) Hendrik Poinar, an evolutionary geneticist at MacMaster University, Hamilton, Canada, said: “Scientists have always thought that because mammoths dominate vast territories — from Western Europe to Central North America — because so North American mammoths do not have any significant role in the evolution of this animal. “

To explore the true history of mammoths, Poinar and colleagues have used the past 3 years to collect ancient DNA from 160 samples of mammoths of various types from Europe, Asia to North America, from there. they built the pedigree tree of the elephant. Many scientists believe that all black-haired mammoths are a related family belt across the 1,000-mile-long Bering land that connects Alaska to eastern Siberia.

Instead, the Bering strip may be a barrier rather than an open corridor between the East and the West, because the blend of mammoths of the ancient and modern worlds seems rare, new research suggests. know. The researchers explain the strip of land may be like a tundra and unsuitable for the life of large creatures. Groups of black-haired mammoths are genetically separated and developed individually to form distinct herds.

Siberian mammoths suddenly mysteriously weakened about 40,000 years ago, and migrating American elephants quickly replaced them. A picture of a black woolly mammoth.

They suddenly disappeared from the ground and were knocked out by the North American mammoth. ”

These findings are beyond the knowledge of past scientists because such a genetic replacement is “very difficult, or it can be said inexplicable by examining teeth, dentin or bones,” Poinar explained. The replacement of the aforementioned species is not uncommon on a small scale, “the same thing can happen on a continental scale,” said researcher Ross MacPhee, curator of mammal at the Museum of History. US course in New York, said.

Considering the cause of the decline on the continental scale, MacPhee said: “there are still a lot of unexplained things.” He doesn’t think competition among different mammoth strains is the culprit. Excessive hunting by humans is also unreasonable.

“Humans were present in both Asia and North America at the time, but the number of mammoths in North America did not decline,” he said. Of course the plague was immediately mentioned, but we have not made any progress on this issue yet.
