Interesting article, but do the Indigenous people think their world would never had changed. If the Europeans had not settled, the Asians would have, Russia had a presence off the coast of Alaska long before other Europeans began to settle. Also, even though their were various tribes in certain parts of what was to become America. There were vast areas that had no people, never had any people.. The people who did populate certain areas had no written language, no horses, no knowledge of the wheel. While some were more advanced. Navahoe, Cherokee, others were still at the hunter, gather stage of development. They were the victims of progress. Victims of a far more advanced civilization. Sad to say, but they did not have a snow balls chance in hell.
