Which theory do most scientists believe about the first inhabitants of North Amercia?

Answer 1

Most scientists believe in the theory of the Bering Land Bridge, also known as the Beringia theory or the Solutrean hypothesis. This theory proposes that the first inhabitants of North America migrated from Siberia to Alaska across a land bridge called Beringia, which was exposed during the last glacial period when sea levels were lower. These early inhabitants then spread throughout the continent over time. This theory is widely accepted due to geological, archaeological, and genetic evidence that supports the idea of a Beringia migration route.
