phaedrus - I have never seen a claim that the Native Amnerican population was 100 million. i did see one idea - more of a conjecture - that the Native American population was significantly higher before European cilization arrived. However, it wasn't right before white people came. it was many centuries before. and i think the anthropologists beleived that many Indians died at that earlier time because of some sort of epidemic. it will probably take a long time for people to work out if these theories are true. maybe we will never know.
