For the very first meter , scientists have bring forth genetical evidence that today ’s endemic North and South Americans are all descended from a individual universe that trekked across the Bering Edwin Herbert Land bridge from Asia .
For the past 20 years , anthropologist have arguedover whether the first Americans come to the New World by walking over a land bridge across the Bering Strait , or by ocean from southwest Europe(the so - called the Solutrean surmise ) . A familial psychoanalysis ofa one - year - old Late Pleistocene human from a Clovis burying website in westerly Montanamay have settled the outlet once and for all .

The 12,600 year - old systema skeletale — which the anthropologists are now calling the “ missing contact ” — was accidentally uncovered by construction workers in 1968 . According to the subject field ’s authors , some 80 % of all present - twenty-four hours native populations in North and South America are direct posterity of the Clovis boy ’s kinsperson , and the remaining 20 % are still more closely associate to the Clovis family than any other mass on the satellite .

The CBC reports :
The genetical depth psychology found that the boy is less closely related to to Cree , Algonquin , and Ojibwa Native Americans in Canada than to the Maya of Central America and the Karitiana of Brazil . That can comfortably be explained , the scientist say , if he belong to a universe that is directly ancestral to the South American clan .
The most likely scenario , sound out Texas ’s Raff , is that man reached easterly Beringia from Siberia 26,000 to 18,000 years ago . By 17,000 years ago , receding glaciers permit them to span the Bering Strait . Some migrated down the Pacific coast , hit Monte Verde in Chile by 14,600 class ago , while others – including the ascendent of Anzick-1 – headed for the Department of the Interior of North America .
Today ’s Native Americans are “ direct descendants of the citizenry who made and used Clovis tools and bury this child , ” the scientists wrote . “ In correspondence with old archaeologic and genetical studies , our genome analysis refutes the possibility that Clovis originated via a European migration to the Americas . ”
All this being say , many expert are not convinced , including Oxford University geneticist Stephen Oppenheimer . “ They have n’t produced evidence to controvert the Solutrean conjecture , ” he is quoted in the CBC clause . “ In fact , there is hereditary evidence that only the Solutrean hypothesis explain . ”
