Until a few years ago it was agreed that Clovis, who lived 13,200 years ago, were the first Americans. But there are other clues and evidence, that in reality some men (and woman) hung around for the Americas for a while. Eske Willerslev, University of Copenhagen, and six colleagues have found fossilized human feces in a cave in Oregon. Thanks to the analysis of radioactive carbon that these droppings were well cagati 14.300 years ago! About 1000 years before the birth of culutra Clovis! Who were the first since the Yankees? Analysis of mitochondrial DNA extracted from faeces was that these people belonged to the haplogroups A2 and B2 (2 of 5 found in the indigenous people of America, both present as well as in Siberia).
