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.
Prehistoric Europe
Prehistoric Europe is the designation for the period of human presence in Europe before the start of recorded history, beginning in the Lower Paleolithic. As history progresses, considerable regional irregularities of cultural development emerge and increase. The region of the eastern Mediterranean is, due to its geographic proximity, greatly influenced and inspired by the classical Middle Eastern civilizations, and adopts and develops the earliest systems of communal organisation and writing. The Histories of Herodotus (from around 440 BC) is the oldest known European text that seeks to systematically record traditions, public affairs and notable events. In contrast, the European regions furthest away from the ancient centers of civilisation tended to be the slowest, regarding acculturation. In Northern and Eastern Europe in particular, writing and systematic recording was only introduced in the context of Christianization, after 1000 CE.
Widely dispersed, isolated finds of individual fossils of bone fragments (Atapuerca, Mauer mandible), stone artifacts or assemblages that suggest Lower Paleolithic palaeo-human presence are rare and typically separated by thousands of years. The karstic region of the Atapuerca Mountains in Spain represents the currently earliest known and reliably dated location of residence for more than a single generation and a group of individuals. Prolonged presence has been attested for "Homo antecessor" (or "Homo erectus antecessor", "Homo heidelbergensis" and Neanderthals.
