Coastal Route Theory

What archaeological discovery significantly challenged the long-held theory of human migration to America?

• Clovis spear points found in North America.

• Ancient settlements discovered on Cedros Island, Mexico.

• Evidence of human occupation at Monte Verde, Chile, dating to 14,500 years ago.

• Footprints found on Calvert Island, British Columbia.

What new theory of human migration to the Americas emerged after the discovery at Monte Verde?

• Humans traveled across the Atlantic Ocean.

• Humans sailed down the Pacific coast from Beringia.

• Humans crossed a land bridge from Asia to South America.

• Humans arrived via an ice-free corridor through the center of North America.

What type of archaeological evidence found on Cedros Island, Mexico, suggests early human adaptation to coastal environments?

• Large Clovis spear points.

• Footprints preserved in clay.

• Stone tools and clam shells.

• Evidence of large game hunting.

Why is Calvert Island in British Columbia a significant site for finding early coastal human settlements, despite rising sea levels?

• The island was never covered by ice sheets.

• The sea level rise was minimal (around 2 meters) due to the land rising.

• It was a major hub for megafauna hunting.

• Researchers used advanced underwater excavation techniques.
