Ice age groups in the ancient northern coast of China helped make up the first wave of people to settle the New World, a new DNA study suggests.

The ancient groups may have also migrated to Japan, potentially helping explain similarities in Stone Age artifacts in the Americas, China and Japan, according to the study, published Tuesday (May 9) in the journal Cell Reports.
