Human Migrations I Native American populations in North and South America have mitochondrial DNA haplotypes that can be traced to populations in northeast Asia. The Alcut and Eskimo populations in the far northern parts of North America possess a subset of the same haplotypes that link other Native Americans to Asia, and also have several additional haplotypes that can be traced to Asian origins but are not found in native populations in other parts of the Americas. Provide a possible explanation.
