Who was more advanced: The Aztecs or the Incas?

Answer 1

Incas.

The Inca made many discoveries in medicine. They performed successful skull surgery, which involved cutting holes in the skull to release pressure from head wounds. Coca leaves were used to lessen hunger and pain, as they still are in the Andes. Messengers chewed coca leaves for extra energy to carry on their tasks as runners delivering messages throughout the empire.

The Inca diet consisted primarily of fish, vegetables, nuts, and Maize (corn), supplemented less frequently with the meat of cuyes (guinea pigs) and camelids. In addition, they hunted various animals for meat, skins and feathers. Maize was malted and used to make chicha, a fermented alcoholic beverage. The Inca road system was key to farming success as it allowed distribution of foodstuffs over long distances. The Inca also constructed vast storehouses, which allowed them to live through El Niño years while neighboring civilizations suffered.
