The study has just been published in the journal Here, geneticist Connie Muligan of the University of Gainesville described the discovery as ‘jaw-dropping’.The colonisation of America has for decades been a hotly debated topic among researchers, with one of the big questions being who the first Americans were and where they came from.This reveals a meeting between two branches of modern man: one branch that followed the east coast of Asia, and one that travelled east from Europe to the steppes of Asia.The researchers cannot at this point say with any certainty exactly where the two branches coverged, but they estimate that they met after the East-Asian lineage split into distinct groups in the high northeast at the gate to America in the vast land area between Siberia and Alaska, known as Beringia.They had expected to find an east-Asian haplotype, as studies have shown that 97 percent of living Native Americans have one of four mitochondrial haplotypes called A, B, C and D, which outside of America are found in eastern Asia.(The remaining 3 percent is the mysterious exception known as haplotype X, which we shall get back to).
