20 thousand kilometers on foot From northern Asia to the southern end of South America, several generations, thousands of years: this was The longest migration in the history of humanity. The journey was “reconstructed” through genetic investigations by a research group led by Nanyang Technological University Of Singapore.
According to the study, therefore, they were therefore Asian first to make the incredible journey: these prehistoric human beings, who wandered over the earth over ten thousand years ago, would have crossed on foot Over 20,000 kilometers from northern Asia to the southern end of South America.
The work analyzed i DNA sequence data of 1,537 individuals representing 139 different ethnic groupsand involved 48 authors of 22 institutions in Asia, Europe and America. By comparing the models of shared ancestry and the genetic variations generated over time, the team has reconstructed how the groups have divided, moved and adapted to new environments.
In fact, in this way, ancient migratory routes were traced and the times when the populations have also been divided. These routes have provided a detailed picture of how the first human beings have reached the extreme border of the Americas.
In other words, in this way the researchers managed to trace a ancient migratory journey Started in Africa, continued through northern Asia and ended in the land of fire, in today’s Argentine, considered the final border of human migrations on earth.
The conclusions obtained from the results suggested that this pioneering group has really exceeded Extreme environmental challenges to complete his journey through the millennia.
The study, financially supported by the Consortium Genomeasia100kwas published on Science.
