First Peoples & Early Habitation

15,000 BCE – 10,000 BCE

Archaeological discoveries confirm human presence throughout the Americas by this time, and potentially much earlier. Highly skilled nomadic and semi-nomadic groups adapted to diverse climates, developing sophisticated toolkits and deep ecological knowledge.

Key Contributions & Adaptations

  • Glacial adaptation: Navigated complex tundra and coastal ice sheets.
  • Stonecraft: Developed micro-blade and early projectile point technologies.
  • Megafauna hunting: Coexisted with and hunted mammoths, mastodons, and ancient bison.
