Facts

 The sequence-divergence estimates for Haplogroup A, Haplogroup C, and Haplogroup D of Siberian and Native American populations indicate that the earliest inhabitants of Beringia possessed a limited number of founding mtDNA haplotypes and that the first humans expanded into the New World approximately 34,000 years before present (YBP).
