Which people were described as the pioneers and indigenes of mesoamerica

The correct answer is Olmec, Maya

Between 900 and 400 BC, the center of the Olmec empire was La Venta, a city built on a huge plain in the region of the current state of Tabasco, Mexico.

During this period, about 350 thousand people lived in all Olmec cities.

Agriculture was the basis of the economy. The harvests were generous. Along the river banks fertilized by the floods, corn, beans, pumpkin and chili were planted.

Hunting and fishing were complementary to the diet, in addition to the systematic collection of wild fruits and tubers. The agriculture was of the type coivara, with the practice of burning to clean the land and fertilize it with ashes for the next planting.

Commercial practices have made society hierarchical, with sophisticated political and social organization. In addition to integration, there was migration between cities and new types of professionals were born, such as sculpting sculptors and others.
