The Olmecs were one of the earliest Mesoamerican civilizations, settling along rivers and lakes in Mexico between 2000-1000 BC. They domesticated crops like corn, beans, and pumpkins which provided the basis for their agriculture-based society. The Olmecs also domesticated animals and engaged in hunting, fishing, and gathering. They were pioneers in constructing stepped pyramids and temples that housed their gods. Olmec art, sculpture, and ceramics reflected their unique symbolism and culture. Their religious beliefs centered around shamanism and the jaguar as an important animal symbol representing the supernatural.
