If it were true it might explain some things, however it's a blatant falsehood and about a minute and a half of research would tell you that. There is no census on the native peoples of this country prior to their being put on reservations and even when the 90% plus percentage is used by historians they don't mean before the pilgrims landed, they mean well after that into the early 1900s. This was one of the most misleading and chocked full of false information articles I've ever read on Cracked. Reader beware.

They have an example of this in the museum in Gettysburg, PA. Or it was until they re-did the visitors center in which case it might be in the Harrisburg Civil War Museum.
