How the First Americans Got There

In 2013, archaeologists discovered the remains of two ancient babies in Alaska, leading to a groundbreaking genetic analysis published in Nature. The study of one baby's genome, USR One, revealed a distinct genetic group called the ancient Beringians, supporting the Beringian Standstill model. This model suggests that early humans were isolated in Beringia during the Ice Age, leading to genetic diversity. The findings provide insights into the migration and genetic history of the first Americans, highlighting a complex timeline of human movement and adaptation in the Americas.
