a wierd fact I found out is that the native population of the americas declined by up to 95% shortley after columbus. Either cervantes or migellan documented a huge and advanced culture down the amazon when they sailed down there. Much of the pristine forest is actually reforested land that used to be arrable, with multitudes of people. 50 years later when another spanish explorer returned there was nothing, and ever since Migellan or whoever was assumed to be making up stories. In actual fact the diseases that swept through the continents emptied it of people almost entirely in a short time, probably the greatest pamdemic event in the history of the earth, and only recent exploration of the amazon has shown up the archeology. The multitudes of buffalo where probably just a surplus, if 95% more red indians hunted buffalo the population would be alot thinner on the ground.
They also had no horses, and thus no use for the wheel. No real metal, just a little used alloy of gold.
