Abstract
America was peopled from Asia by at least the end of the last ice age, but the exact timing of entry and the composition of the source population are unclear. A new analysis of two rare mitochondrial haplogroups suggests two separate Asian migrations into the Americas, indicating simultaneous but independent Asian source populations for early American colonists.Entities:
