Beringian

I read the research paper "Sinodonty, Sundadonty, and the Beringian Standstill model: Issues of timing and migrations into the New World."

Scientists believe that all Native American people descend from a single population that used to inhabit Beringia, a region that comprises Alaska, eastern Siberia, and western Canada along with several lands that are now below water. Very little is known about the ancient Beringians but a new discovery in Russia might finally give us some clues.
