>Necessary tools being an IQ above 95.They lost because they were retarded and Europeans are high quality men.That’s the obvious conclusion no one wants to admit because it means two things:One, dialectical materialism is wrong, it is biological determinism that drives history.Two, the decline in Europeans is catastrophic, borderline worse than any natural catastrophe.
That logic falls when you know amerindians are just ANE mixed with mongoloids.
The reason why mesoamerica didnt develop technology as eurasia is rather because there was no other civilization in the americas like them, only the guys in the andes were the only others to develop cities, and they were kilometers and kilometers in distance.
They did met each other, since the andes guys traveled by boats to the west of mesoamerica, but this contact was brief.
At say true is amazing what mesoamerican civilizations did without any other civilization helping them, like the invention of writing systems (they are 1 of the 5 civilizations to create writing systems without any help), great infraestructure (calzadas, mayan pavimented roadways, mayan and central altiplane aqueducts, and the Nezahualcoyotl albaradon) and arquitecture that was admired by the conquistadors, great art like scultures (aztec and mayan monolithes) and paintings (cacaxtla and bombapak) and the milpa system, which made the soil productive even more than the eurasian rotative systems.

I find it curious how even though, we associate mayans with the classic period, the most famous city of them was of the post classic (Chichen Itza)
