"Calva's is the first case of cannibalism reported in Mexico for almost 500 years." well considering the entire mexica empire (aztecs) had the worlds largest central population and survived totally upon human meat for their protein and amino acid source,(there is no other way they could have fed themselves), I'd say they made up for any time lost being the largest group of cannibals to ever exist, im a mexican historian with a degree from one of the top latin american history departments in the US btw so yeah no bullshit... aztec is a made up word too, by a white guy oh mexico your so silly
