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.
