I've heard that falsehood from other Eurocentric racists. First Stinker says that they barely managed agriculture or civilization. But then they're burning down huge tracts of forest. I wonder how the Euros built their cabins, forts, villages, towns, cities, and metropolises w/o wood?
Driving game over cliffs is an ancient hunting practice done not just by Paleoindians in N. and S. America, but across the world. As usual Stinker is lying when she claims that American indigenous people used one buffalo out of hundreds killed. Waste of course was inevitable, but meat and hides that were excess were dried and preserved and traded, esp. for foods and items that were unavailable to that locale. There is archaeological evidence that the excess was traded to obtain pottery, grains, other dried non-meat foods, copper (used for decorations), shells, beads made from various materials, tools, toys, and other daily necessities and desires.
Stinker would do well to take a college-level cultural and/or physical anthropology class or two, as I have. I'm fairly sure that that somewhat-teachable simple primate could learn something. She might develop a better sense of how creative and intelligent our ancestors really were, no matter what continent they dwelled upon.
