Mitochondrial DNA and Y chromosome diversity and the peopling of the Americas: Evolutionary and demographic evidence
Abstract A number of important insights into the peopling of the New World have been gained through molecular genetic studies of Siberian and Native American populations. While there is no complete agreement on the interpretation of the mitochondrial DNA (mtDNA) and Y chromosome (NRY) data from thes...

A second expansion that perhaps coincided with the opening of the ice‐free corridor probably brought mtDNA haplogroup X and NRY haplogroups P‐M45b, C‐M130, and R1a1‐M17 to North and Central America.
