Haplogroup B is believed to have arisen in Asia some 50,000 years before present. Its ancestral haplogroup was Haplogroup R.
Haplogroup B is found throughout modern Asia. Its subgroup B2 is one of five haplogroups found in the indigeneous peoples of the Americas, the others being A, C, D, and X. In human genetics, Haplogroup A is a human mitochondrial DNA (mtDNA) haplogroup. ...
In human genetics, Haplogroup X is a mitochondrial DNA (or mtDNA) haplogroup, ie a group of possible DNA sequences for a cell mitochondria. ...
Since the migration to the Americas by the ancestors of Native Americans is generally believed to have been from Siberia, it is especially surprising that Haplogroup B is the only haplogroup found in Native Americans which is not found in modern Siberian populations. The question of when humans first entered the Americas (the New World) and how they arrived has been debated for centuries, and will probably continue to be for many more years to come in the anthropological community. ...
