I didn't make generalizations.   I gave facts about indigenous understanding of crops.   Credit for understanding genetic dominance was given to Mendel later, after settlers had acquired the knowledge and the understanding made its way back to Europe.   Tribes were also grafting like trees to provide more than one kind of fruit on a tree.   The Incas had over 200 types of potatoes alone.    

Native women weren't feminists.   Europeans didn't play well with each other, either.  Some scholars believe that Europe has been the most war-torn continent in the world for last 1000+ years.   

The influence of the Iroquois philosophy, justice and government structure on the Constitution is well known.   Much of the best of the Constitution concerning individual freedoms and rights was a direct result of the influence of the Iroquois.

Your contempt is misplaced.   Your belief in the cultural superiority of Europeans is a common fantasy.
