Thus came the ancestors of today's Native Americans on the mainland
They entered the continent into a single "wave" and not several, as was believed, now about 23,000 years ago. A study reported in the journal Science argues that the first settlers of America penetrated the continent into a single "wave" and not several, as previously thought, now about 23,000 years ago. There is a strong controversy about when and how the ancestors of native  Americans came to the New World from Siberia and explains the Complutense University of Madrid (UCM), one of the centers engaged in the research led by the University of Copenhagen (Denmark). Archaeological evidence argued that the first settlers have stepped American lands between 23,000 and 15,000 years . And it is accepted that the ancestors of Native Americans are descendants of Siberian, who crossed the Bering Land Bridge. But, date and pattern of population displacement data were unknown so far. To shed light on these issues, they have been sequenced and compared genomes of ancient and modern people of America, Siberia and Australia. The results pointed to emigration in the last glacial maximum of Siberian America. The evidence that multiple waves give input has been ruled out in this study . The common Siberian origin for Native Americans is the right that the researchers have been able to certify description.
