With regards to the concept of prehistoric waves of migration into North America - I'm confused by what that actually means. Does that mean groups/tribes would pulse into North America and somehow displace the people from the previous waves? Did the people from those previous waves largely die out or did they generally mix with the new waves? Is there a generally agreed upon number of major migration waves?
