"When most people think about ancient Mexico, the first civilizations that come to mind are the Incas, Aztecs and the Maya. However, during the early 1940′s archeologists uncovered a civilization known as the Olmecs of 1200 BC, which pre-dated any other advanced civilization in the Americas.
The Olmec civilization, which was of African origin and dominated by Africans, was the first significant civilization in Mesoamerica and the Mother Culture of Mexico."
