If anyone has ever studied the Ojibway people, and compared them with their neighbors, the Dakota people, they are clearly of two different racial stocks. Almost certainly, the precursors of these people came from the east, rather than the northwest, as they migrated to the North American continent.
the Ojibway people are part of a much larger group called Algonkians, related to the Cree, the Micmac, Shawnee and others around the northeaster quadarant of North America. They have the highest percentage of haplogroup X, which was also extant in Siberia during the Ice Age. A small percentage of Europeans also carry the X haplogroup. Look it up.
Algonkians seem to have been the initial immigration over the Bering Strait.
But remember the Bering Strait land-bridge was actually a sort of country unto itself, not just a ‘bridge’. People probably lived on it for many generations.
Physically there is not a lot of difference between the Algonkian-speaking people, including the Ojibway, and the Dakota. But the languages are totally different.
But there is an interesting correspondence between some ancient Slavic folk tales and native american myths, which exist nowhere else; that of the ‘earth diver’, for instance.
Not so difficult to imagine N. America being filled from both east and west.
