In this period began the settlement of ancient societies, groups of small villages or small houses inhabited by large families. However, there was still not a social structure until the middle and late Preclassic period. In agriculture, societies that settled in states such as Puebla, Tlaxcala and Tabasco started to domesticate wild plants such as corn, amaranth, pumpkin, chili pepper and green tomato. On the other hand, in the peninsula of Yucatan and Mexico, they had not yet domesticated plants.
