I've been watching this issue unfold for several years. The Kennewick Man is the trigger to this debate and really heated the atmosphere. Without the completed DNA tests...we are left with the strong possibility that around 7000 years ago...a non-Indian existed in the Pacific northwest. The amusing part of this...is that numerous tribes have attempted to grab Kennewick and forbid DNA testing. Reason: if you have one shred of evidence that shows white Europeans actually were here...then the "holy grail" of the Indian empire is blown.
In the last five year...this whole issue goes into overdrive with a significant find in Penn...which leads historians to a slightly different history...not only did Asians cross over the Alaskan or Canadian region....but White Europeans also made their way over. At some point...one group met another...in whatever numbers...and the lesser was eridicated from the American landscape. We could be very well talking about two native American groups (European and Asian) who met in the eastern US...and with the Asian group being more aggressive and warlike...they simply annihilated a lesser group of Europeans, and assimilated what remained into their tribes.
It changes history to great extent. But a similiar arguement is brewing over Chinese exploration of the Pacific in the early 1400's....and they may have discovered America 70 years prior to Columbus. Enough evidence exists which forces everyone to go back to the drawingboard.
By 2010...we may have two major parts of American history...which may have to be rewritten...with both adults and children learning a vastly different past.
We already have a bandwagon and a magazine. We just need a theme song now.

I demand reparations! Or you can just give me 5% of Foxwoods.
In Heavener, Oklahoma there is evidence of European explorers predating Columbus. The Heavener Runestone has markings made by Vikings.
Some new information on the Early Coastal Migration theory at this link.
This would place the migration from SE Asia much earlier than 7000 years. Stay tuned.
