Early Human Migration Evidence

The video explores theories of early human migration to America, initially focusing on the Clovis theory, which suggested humans followed megafauna across the Bering Strait. This theory was challenged by the Monte Verde site in Chile, indicating earlier human presence. A new theory emerged, proposing coastal migration by boat. Researchers are investigating both land and underwater sites for evidence, with significant findings on Cedros Island and Calvert Island. However, more evidence is needed to confirm the coastal migration theory.

What was the primary reason early humans were believed to have crossed the Bering Strait?

• To follow large game animals

• To escape predators

• To explore new territories

• To find new agricultural land

What was the significance of the spear points found in North America?

• They were used for fishing

• They indicated big-game hunting

• They were decorative items

• They were used in agriculture

What significant discovery at Monte Verde challenged the Clovis-first theory?

• Human occupation dating back 14,500 years

• Evidence of agriculture

• Fossils of extinct animals

• Advanced stone tools

What was the primary focus of researchers after the Monte Verde discovery?

• Analyzing animal migration patterns

• Studying climate change

• Investigating the Pacific Coast

• Exploring inland areas

What type of evidence was found on Cedros Island that suggests early human settlement?

• Metal artifacts

• Cave paintings

• Stone tools and clamshells

• Ancient manuscripts

Why did researchers start mapping the ocean floor off the coasts of Oregon and California?

• To search for shipwrecks

• To locate ancient riverbanks and estuaries

• To find new fishing grounds

• To study marine life

What did researchers hope to find by taking core samples of the ocean floor?

• Mineral deposits

• Oil reserves

• Evidence of early human occupation

• New marine species

What geological event helped preserve evidence of early settlements on Calvert Island?

• Tsunamis

• Minimal sea level rise

• Earthquakes

• Volcanic eruptions

What was found on Calvert Island that provided evidence of early human activity?

• A burial site

• A large stone monument

• 29 preserved footprints

• Ancient pottery

What is still needed to confirm the coastal migration theory?

• More well-documented coastal sites

• Satellite imagery

• DNA evidence

• Written records
