The Olmecs came from Africa. There is no evidence that the Olmec existed in Mexico before 1200-1100 BC. The archaeological evidence suggest that the Olmec “miraculously appear on American soil”.
Who were the Olmecs?
Andrzej Wiercinski claims that some of the Olmecs were of African origin. He supports this claim with cranial evidence from two Mesoamerican sites: Tlatilco and Cerro de las Mesas. Tlatilco is a site in the Valley of Mexico. Although outside the Olmec heartland, Olmec influences appear in the architectural record.
The Olmecs lived in hot, humid lowlands along the coast of the Gulf of Mexico in what is now southern Veracruz and Tabasco states in southern Mexico. The first evidence of their remarkable art style appears about 1200 bce in San Lorenzo, their oldest known building site.
Where did the Olmec civilization emerge geographically? The Olmec civilization emerged out of south-central Mexico in the tropical lowlands.
Overview: The Olmec lived along the Gulf Coast of Mexico in the modern-day Mexican states of Tabasco and Veracruz. The name Olmec is an Aztec word meaning the rubber people; the Olmec made and traded rubber throughout Mesoamerica.
The legendary origin of the Aztec people has them migrating from a homeland called Aztlan to what would become modern-day Mexico. While it is not clear where Aztlan was, a number of scholars believe that the Mexica—as the Aztec referred to themselves—migrated south to central Mexico in the 13th century.
Some historians assert that the Mayans were the descendants of the Olmecs.
Linguistic evidence has contributed to the ethnic identity of the archaeological Olmecs: they spoke a Mixe-Zoquean language. The Olmecs produced the earliest complex civilization in Mesoamerica (c. 1200–400 bce), and it was located mainly in the same area where Mixe-Zoquean languages are found.
The Sumerian civilization is the oldest civilization known to mankind. The term Sumer is today used to designate southern Mesopotamia. In 3000 BC, a flourishing urban civilization existed. The Sumerian civilization was predominantly agricultural and had community life.
To quickly sum up, the Maya were first but learned a lot from the Olmecs, who started 1,200 years later.
Among their many accomplishments, Olmecs created the first cities in North America. Many archeological sites are known for this culture, but only two were large and splendid enough to qualify as cities: San Lorenzo and La Venta.
The Olmec civilization presents something of a mystery, indeed, we do not even know what they called themselves, as Olmec was their Aztec name and meant ‘rubber people’. Due to a lack of archaeological evidence their ethnic origins and the location and extent of many of their settlements are not known.
The oldest form of the calendar—the solar round—was likely invented by the Olmec, epi-Olmec, or Izapans about 900-700 BCE, when agricultural was first established. The sacred round may have been developed as a subdivision of the 365-year one, as a tool specifically designed to track important dates for farming.
The Aztecs were the Native American people who dominated northern Mexico at the time of the Spanish conquest in the early 16th century. A nomadic culture, the Aztecs eventually settled on several small islands in Lake Texcoco where, in 1325, they founded the town of Tenochtitlan, modern-day Mexico City.
