First Americans Used Two Distinct Routes, Genetic Study Suggests
NEW YORK (GenomeWeb News) – The first people to migrate from Beringia to the Americas did so via two routes — one along the Pacific Coast and another by an inland path east of the Rocky Mountains, according to research appearing online today in Current Biology. A team of Italian and American researchers sequenced dozens of mitochondrial genomes from individuals belonging to two rare haplogroups. Based on their phylogenetic and phylogeographic analyses of these and other mitochondrial sequences, the researchers concluded that two groups of Paleo-Indians migrated from Beringia to the Americas roughly 15,000 to 17,000 years ago via different paths. And, they argue, that dual migration may shed light on everything from Native American linguistics to archeology.
