Pre-Columbian era
The earliest known civilization is the Olmec. This civilization established the cultural blueprint by which all succeeding indigenous civilizations would follow in Mexico. Pre-Olmec civilization began with the production of pottery in abundance, around 2300 BCE in the Grijalva River delta. Between 1600 and 1500 BCE, the Olmec civilization had begun, with the consolidation of power at their capital, a site today known as San Lorenzo Tenochtitlán near the coast in southeast Veracruz. The Olmec influence extended across Mexico, into Central America, and along the Gulf of Mexico. They transformed many peoples' thinking toward a new way of government, pyramid-temples, writing, astronomy, art, mathematics, economics, and religion. Their achievements paved the way for the Maya civilization and the civilizations in central Mexico.
Cradle of civilization
The earliest evidence of agriculture in the Andean region dates to around 4700 BC at Huaca Prieta and Paredones. The oldest evidence of canal irrigation in South America dates to 4700 to 2500 BC in the Zaña Valley of northern Peru. The earliest urban settlements of the Andes, as well as North and South America, are dated to 3500 BC at Huaricanga, in the Fortaleza area, and Sechin Bajo near the Sechin River.
