i have never understood this puzzle of history.
Do you think they originated there, were created there, and were too retarded to figure out they could move to warmer climates?
Well, that last part could be true, though unlikely; it is possible that they didn't understand that if they moved a certain direction far enough, the climate might be different. As I said, I highly doubt that to be the case.
That being said, their ancestors did come from possibly warmer and/or colder climates. And the mass migration into North America was not a one-stop trip to the first place they discovered that was free of dangerous animals... nor did everyone that settled the first camp/tribe/settlement decide to remain there. Some founded other nearby settlements, and some likely went South and either established "Native American" tribal settlements or joined up with the original group wherever they settled (the group with which they traveled into North America).
The Eskimos were satisfied. There were likely many who grew curious about what lay South, or were dissatisfied, and ended up moving South. So, they did... but the entire ethnic group did not pick up and leave, only a handful in comparison.
Of course, this is most likely a troll post... oh hell, already typed it up, it stays.
