According to the research, migration occurred about 13 thousand years ago.
The remains of bison told the researchers about the possible period of the creation of a corridor of migration during the glacial period. This was reported by experts from the University of California.
According to scientists, the remains of bison in the territory of Alaska and the Yukon indicate that during the last glacial period, most of the animals, surviving in a sudden decrease in temperature on the planet was forced to migrate from the Northern parts of the continents in the South. According to the research, migration occurred about 13 thousand years ago.
Scientists say that the bison have also migrated along with people and in the later period. This is evidenced by the animal remains found in the territory of Alaska. Together with them were found the bones of Homo antecessor, who lived in those regions. According to experts, during the cold weather they were primarily sedentary, moving very rarely.
The studies of the remains of the bison were also able to determine that colonization the first people of the territory of modern America dates from about the 190-th century BC. Then Homo Sapiens along with the animals migrated glaciers from the European continent in a westerly direction. After that they settled along the Pacific coast, over time, shifted closer to the center of the continent.
