Dusty belongs to mtDNA Haplogroup B2, one of four major haplogroups that’s prevalent among Native Americans. Haplogroup B2 is unusual amongst Native American haplogroups because there is very little evidence that they crossed the land bridge between Russia and Alaska.
Most haplogroups spread from the north to the south, as you would expect from a land bridge crossing. Strangely, mtDNA haplogroup B2 spread from the South to the North, and it is most commonly found in Peru. This evidence suggests that Crawford’s ancestors crossed the Pacific Ocean sometime during the last Ice Age. This is bolstered by the fact that many native Pacific Islanders only belong to mtDNA haplogroup B2. Additionally, their closest mtDNA haplogroup, B4b1, is found in Southeast Asia.
