1. When did Europeans arrive in the New World according to the genetic data mentioned in the passage?

According to the genetic data mentioned in the passage, Europeans arrived in the New World during the Norse exploration and brief settlement of northeastern Canada at about 1000 C.E.


2. What alternative hypothesis regarding the arrival of native people in the New World is presented in the passage?

The alternative hypothesis presented in the passage suggests that the native people of the New World may have arrived during the late Pleistocene, not from Asia through Beringia, but instead by boat from Europe along the margin of the ice-covered waters of the northern Atlantic.


3. Who proposed this alternative hypothesis, and what is the basis for their argument?

Archaeologists Dennis Stanford and Bruce Bradley proposed the alternative hypothesis. The basis for their argument is the perceived detailed and deep technological and morphological similarities between Clovis technology in North America and the Solutrean tradition of the European Upper Paleolithic.
