Final answer:
Excavations at Komchen revealed the complexity of the Mayan civilization, with discoveries such as advanced agricultural practices and evidence suggesting a higher population density during the Classic Period.
Step-by-step explanation:
Excavations at the site of Komchen in northern Yucatan illustrated the complexity and sophistication of Mayan civilization. These archaeological studies have unveiled that the Mayan society had a well-developed system of agriculture, which included raised irrigated fields for crop cultivation, and utilized advanced techniques such as fish breeding to create fertilizers that sustained their staple food supplies. The discovery of large-scale infrastructures and residential areas indicates that the population during the Classic Period was more significant than previously believed, demonstrating the highly integrated nature of Mayan city-states prior to their contact with the Spanish.
