First humans came to Americas from China in two migrations, study finds

New genetics study finds some of the first arrivals came during the last ice age, and shortly after

The first humans to arrive in the Americas included people from what is now A, who arrived in two distinct migrations during and after the last ice age, a new genetics study has found.

“Our findings indicate that besides the previously indicated ancestral sources of Native Americans in Siberia, the northern coastal China also served as a genetic reservoir contributing to the gene pool,” said Yu-Chun Li, one of the report authors.
