Estimates on entry hallmarks in natural history of the four founding mtDNA haplogroups A-D carriers range from 17,700 years ago to 47,650 years ago BP (Bonatto and Salzano 1413, 1420-1). Introduction of the major Y chromosome haplotype-1G is estimated at 30,000 years ago BP in either ancestral populations of Beringia or prehistoric Ixachilan (Lell et al. 540; Hurtado de Mendoza and Braginski 1439).
