Why does everybody automatically assume the ONLY route to North and South America was by some coastal route that followed the Bering Strait when it was a land bridge? Genotypes include individuals that were clearly similar to Polynesian islanders, and share some of the distinctive genetic makeup. Others look much like Northern Europeans, which brings up the possibility that Leif Ericsson was NOT the first to reach the banks of Nova Scotia. The Ojibway people are quite unlike their neighbors, the Dakotah, and spoke a very different language.
There is no "typical" Indian appearance. Eastern woodlands Indians were very unlike western Plains Indians, and the Mississippian culture had little in common with that of the Northwest in Washington State or British Columbia.
The Ojibway have the highest percent of the so-called 'European gene X' than all other Indians in the Americas.
