The chronology of migration models is currently divided into two general approaches.

The second belief is the long chronology theory, which proposes that the first group of people entered the hemisphere at a much earlier date, possibly 50,000 - 40,000 years ago or earlier.

Early Paleoamericans soon spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. Paleoindian adaptation across North America was likely characterized by small, highly mobile bands consisting of approximately 20 to 50 members of an extended family. These groups moved from place to place as preferred resources were depleted and new supplies were sought. Paleoindian groups were efficient hunters and carried a variety of tools. These included highly efficient projectile points/knives (PP/Ks) of the types mentioned above, as well as less distinctive implements used for butchering and hide processing. During much of the Paleoindian period, bands are thought to have subsisted primarily through hunting now-extinct megafauna

The North American climate finally stabilized by 8000 BCE; climatic conditions were very similar to today's. This led to widespread migration, cultivation and subsequently a dramatic rise in population all over the Americas. Over the course of thousands of years, American indigenous peoples domesticated, bred and cultivated a large array of plant species. These species now constitute 50–60% of all crops in cultivation worldwide.

 were among the largest in the world. These cities grew as centers of commerce, ideas, ceremonies, and theology, and they radiated influence outwards onto neighboring cultures in central Mexico.

While many city-states, kingdoms, and empires competed with one another for power and prestige, Mesoamerica can be said to have had five major civilizations: The Olmec, Teotihuacan, the Toltec, the Mexica and the Maya. These civilizations (with the exception of the politically fragmented Maya) extended their reach across Mexico—and beyond—like no others. They consolidated power and distributed influence in matters of trade, art, politics, technology, and theology. Other regional power players made economic and political alliances with these four civilizations over the span of 4,000 years. Many made war with them, but almost all peoples found themselves within these five spheres of influence.

The decline of the Olmec resulted in a power vacuum in Mexico. Emerging from that vacuum was Teotihuacan, first settled in 300 BCE. By 150 CE, Teotihuacan had risen to become the first true metropolis

 from the Oaxaca region. They lived in apartment communities where they worked their trades and contributed to the city's economic and cultural prowess. By 500 CE, Teotihuacan had become the largest city in the world. Teotihuacan's economic pull impacted areas in northern Mexico as well. It was a city whose monumental architecture reflected a monumental new era in Mexican civilization, declining in political power about 650 CE—but lasting in cultural influence for the better part of a millennium, to around 950 CE.

Maya civilization

Contemporary with Teotihuacan's greatness was the greatness of the Maya civilization. The period between 250 CE and 650 CE was a time of intense flourishing of Maya civilized accomplishments. While the many Maya city-states never achieved political unity on the order of the central Mexican civilizations, they exerted a tremendous intellectual influence upon Mexico and Central America. The Maya built some of the most elaborate cities on the continent, and made innovations in mathematics, astronomy, and calendrics.
