The remains of three people who died on a riverbank in the Kamchatka Peninsula in northeastern Siberia some 500 years ago have yielded a surprising secret: Their DNA shows they had some North American ancestry.
The remains of three people who died on a riverbank in the Kamchatka Peninsula in northeastern Siberia some 500 years ago have yielded a surprising secret: Their DNA shows they had some North American ancestry, according to a study published today. Considered alongside other ancient and modern genomes, the results suggest that although the ancestors of today’s Native Americans came from Asia, the passage was not one way.
When the last ice age ended about 11,500 years ago and glaciers melted, the Bering Sea rose and divided the two continents. But migrants continued to arrive, mixing with and replacing earlier groups to shape the modern genetic landscape of Indigenous Americans. By 5000 years ago, people had settled across Alaska and northern Canada.
The researchers roughed out a family tree by comparing the trio’s genomes with those from modern populations and other ancient genomes from the region and across the Americas. The scenario that best explains their history Other ancient genomes analyzed in the study underscore that ancient Siberia was a human crossroads. Six came from the mountainous Altai region near/in Mongolia, dating to between 5500 and 7500 years ago. Five of these so-called Altai hunter-gatherers belonged to a population that apparently gave rise to several later peoples who spread throughout the Central Asian steppe during the Bronze Age.
