Final answer:
The Olmec civilization began in the jungle lowlands along the Gulf of Mexico coast, where they established complex societal structures such as La Venta and were considered the 'mother culture' for later Mesoamerican civilizations.
Step-by-step explanation:
The Olmec civilization began in the jungle lowlands of the Gulf of Mexico coast. Notably recognized for their contributions to Mesoamerican culture, the Olmec people erected significant sites such as La Venta around 900 BCE, making it a prominent center for their culture. They were trailblazers in many areas, including government, trade, religion, and the arts, creating a foundation for subsequent Mesoamerican civilizations like the Maya and the Aztec.
La Venta became a crucial hub for the development of Olmec society, showcasing their achievements in agriculture, architecture, and artwork, such as the iconic giant head sculptures. The Olmec also developed a system of trade that was crucial in the rise of an elite class within their culture.
Furthermore, the Olmec civilization is generally acknowledged as the forerunner of all Mesoamerican cultures and has been recognized as the 'mother culture' for the region's later complex societies.
