The Bering Land Bridge between Russia and the Americas was approximately 50 feet deep at its lowest point during the ice age.
It is theorized that during the ice age, this area dried up, allowing humans to walk across and settle in North America.
There is uncertainty about this theory; it remains a hypothesis.
Recent findings, like the 30,000-year-old mammoth skeleton in San Diego showing butchering marks, challenge the timeline of human migration into the Americas and may disprove this theory altogether.
Primary units of Native American society are tribes rather than cities or empires.
The size of tribes varies; larger tribes are found in the Southeast while Plains tribes are generally smaller, as they were nomadic and followed buffalo.
Estimated populations of tribal settlements range from about 10,000 to 15,000 at their peak, but this is still debated.
European diseases, particularly smallpox, significantly affected Native populations upon their arrival; some tribes faced epidemics in the 1700s, while others were delayed in contact with European settlers.
Corn (Maize): The most significant crop in North American tribal culture, important for sustenance across various tribes.
Other notable crops:
Potatoes: Recognized for their association with Europe only after the 1500s, they were unknown before then.
Tomatoes and Squashes: Also unique to the Americas prior to European contact.
The adaptability of corn allows it to be cultivated in diverse climates, making it a versatile staple crop.
Bison: The most notable and unique animal, significant to plains tribes.
Other notable animals include:
Turkeys
Elk
White-tailed Deer: While deer exist in Europe, species differ; North American deer are different from reindeer found in other regions.
Native Americans generally regard land as communal and spiritual, not owned in the European sense.
Land use entails planting and resource gathering, but the idea of owning land outright, as in individual exclusive ownership, is foreign to their culture.
Land is seen as having spiritual significance; thus, ownership claims are based more on use rights rather than ownership rights.
Property that exists independently of use, such as unclaimed land, cannot be owned outright, as it has existed before the individual and will continue afterward.
Private property does exist in terms of created items and cultivated crops, such as bows and arrows or harvested plants.
Many Native American tribes rely on oral traditions to pass down history and culture; only a few tribes, like the Iroquois and Navajo, possess written languages historically.
Knowledge about tribes without written records tends to be limited, affecting historical accounts and understanding.
Northeast: Includes tribes located close to the Eastern seaboard.
Southeast: Home to some of the largest tribes, such as the Crees, Seminoles, and Cherokees.
Plains: Notable tribes include the Sioux, Pawnee, Comanche, and Crow.
Southwest: Key tribes are the Navajo, Apache, and Pueblo.
The Great Basin tribes (Rocky Mountains) are often overlooked in narratives but are numerous.
Each tribe is unique with distinct cultures, languages, and traditions, and cannot be broadly grouped without recognizing differences.
