Nomad wrote:While there might still be a group of blindly stubborn Beringia-only scholars out there, the prevailing trend is towards the recognition that ancient migrations to the Americas occurred as well via both the North Atlantic and the South Pacific. Evidence from multiple disciplines has made this pretty much a foregone conclusion among the new generation of anthropologists and archaeologists. I'm surprised that Feder would make a statement like the one you attribute to him. I find it hard to believe he is not aware of the growing body of evidence that demonstrates multiple ancient migration paths to the Americas.
ETA: Here is one recent examination of evidence contradicting the "Beringia Only" theory of Amerindian origins: The First Americans: Race, Evolution and the Origin of Native Americans
Where in that book does it support two migrations of people from the middle east to the Americas? If your only point is that there may be some evidence for transoceanic crossings at times that don't fit the Book of Mormon narrative and by people who don't fit the Book of Mormon narrative (polynesians, Japanese, etc.), then it does absolutely nothing to help your case.
