Early Human Migrations and Paleo Indian Life

Flashcards covering key concepts about the migration of early peoples into the Americas, Paleo Indian life, and agricultural innovations.

Beringia

A vast land bridge that connected present-day Russia and Siberia to Alaska, allowing early migrations of humans.

Paleo Indians

The early inhabitants of the Americas who migrated across Beringia from Siberia.

Solutrean hypothesis

A theory suggesting that the first Americans migrated from Europe via small boats across the Atlantic Ocean.

Genetic analysis of Kennewick Man

Revealed that he had dark hair, dark eyes, and a close relationship with modern Native Americans.

Migration Waves

Multiple migratory movements of diverse Paleo Indian groups over several millennia into the Americas.

Environmental adaptations

Techniques and tools developed by Paleo Indians to survive in various ecological zones across the Americas.

Agriculture in Mesoamerica

The domestication of maize and other crops approximately 7,000 years ago, which became the foundation of Native American agriculture.

Nitrogen fixation

The natural process used by beans to replenish nitrogen in the soil, benefiting the Three Sisters planting method.

Population density in 1500 CE Americas

Estimated at about three people per square mile, with significant regional variations.

Indigenous cultural adaptations

Diverse farming and hunting strategies that evolved among descendants of Paleo Indians leading to varied Native American cultures.
