DNA analysis on Native Americans
Confirming the Siberian Migration
The first research on living Native American tribes showed they were comprised of four distinct mtDNA haplogroups called A, B, C, and D. This means that the Native Americans are derived from four different lineages.
These haplogroups were also found in native populations in Central and South America. Utter mtDNA research utilizing ancient remains recovered in the Americas validated these four haplogroups. Three of these haplogroups, A, C, and D are found primarily in Siberian Asia.
The B haplogroup, however, is found only in aboriginal groups in Southeast Asia. China, Japan, Melanesia, and Polynesia.
