Study Notes

Migration to the Americas

  • Anthropologists and archaeologists believe migration to the Americas occurred via a land bridge called Beringia.
  • This land bridge existed during the last glacial period (20,000-30,000 years ago) when sea levels were significantly lower.
  • Beringia connected present-day Russia and Alaska.
  • Mitochondrial DNA evidence shows a connection between Native Americans and Siberian peoples.

Evidence for Migration

  • Archaeological evidence shows similar burial practices and tools on both sides of Beringia.
  • Biological evidence from mitochondrial DNA shows similarities between Native Americans and Siberian groups. These similarities are not found in DNA from people in Europe, Africa, or other parts of Asia.
  • Other theories, like a water route or a South Pacific route, have been proposed. However, archaeological evidence from these routes would now be underwater, and DNA evidence strongly suggests a Siberian origin.

Native American Societies & Development

  • Initially, Native Americans were primarily hunter-gatherer societies.
  • Agriculture developed in the central valley of Mexico around 5,000 years ago and spread outwards.
  • Major agricultural areas in North America include the Anasazi (Chaco Canyon), the Adena and Hopewell (Ohio), and the Mississippian/Cahokia (Illinois) regions.
  • Crop cultivation led to population growth, social hierarchies, and advancements in culture.
  • Cultures like the Mayan, Toltec, and Aztec (Mexica) developed in Central Mexico.
  • Many other groups combined cultivation with hunting and gathering.
  • Seasonal population fluctuations (feast and famine) were common for many groups.

Contact with Europeans

  • Native American populations were largely isolated before contact with Europeans.
  • Trade routes existed, but contact was seasonal at best.
  • After 1492, contact with Europeans led to a widespread decline in Native American populations.
  • European diseases, to which they had no immunity, were the primary cause of death.
  • Diseases like smallpox, influenza, and others decimated entire tribes.
  • Lack of domesticated animals in the Americas meant lack of immunity to these diseases widespread amongst Europeans.
  • Some tribes were completely wiped out, while others were severely weakened, making them more vulnerable to European influence.
