B Anthropologists believe that the earliest settlers migrated from Asia thousands of years ago
Explanation:
- The first American inhabitants, Paleo-Indians, arrived in the New World with a single, unique wave of migration from Siberia 23,000 years ago, to be divided into today's groups only later, DNA research showed.
- Most scientists agree that the continent was inhabited by people crossing the Bering Land Bridge (at that time there was a crossroads between Siberia and Alaska), and archaeological discoveries so far indicate that humans were present on American soil 15,000 years ago.
- These migrants split into two major groups about 13,000 years ago, at a time when glaciers were melting and roads inland were opening up in North America, experts say.
