The researchers analyzed human remains from the site, which is located in southern Mexico, and compared what they found with climate data and records of drought from cave deposits beneath the city, Kennett explained. The study suggests that reliance on maize crops without a centralized system of long-term grain storage, minimal irrigation systems, and a sociopolitical system led by elites who had competing political interests contributed to the collapse of the city.
