Sad that New World people don't get the representation they deserve in these charts. If only folks knew how incredible the Inca were, like the Romans of South America. They made roads everywhere, created the potato and created super engineered terraced farms at different elevations to create deliberate ecosystems for those crops, and integrated/conquered all their neighbors.
Incas were able to construct "one of the greatest imperial states in human history" without the use of the wheel, draft animals, knowledge of iron or steel, or even a system of writing.
