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.
South Asia
The history of core South Asia begins with evidence of human activity of "Homo sapiens," as long as 75,000 years ago, or with earlier hominids including "Homo erectus" from about 500,000 years ago. The Indus Valley Civilization, which spread and flourished in the northwestern part of South Asia from c. 3300 to 1300 BCE in present-day Northern India, Pakistan and Afghanistan, was the first major civilization in South Asia. A sophisticated and technologically advanced urban culture developed in the Mature Harappan period, from 2600 to 1900 BCE.
