Module 1 • Deep Time & Ancient Migrations
1. The First Peoples, Deep Time & Ancient Migration
- Beringia: During the last Ice Age (up to ~13,000–20,000 years ago), massive continental glaciers locked up enormous amounts of ocean water. Global sea levels dropped by roughly 100 metres, exposing a vast land plain between Siberia and Alaska.
- Scale of Beringia: It was not a narrow bridge or fragile crossing; it was a massive, habitable tundra plain up to 1,600 km (1,000 miles) wide.
- Migration Motive: Ancient hunter-gatherers crossed Beringia following migrating herds of Ice Age megafauna—specifically woolly mammoths, steppe bison, and caribou.
- The Traditional "Clovis First" Theory: For decades, archaeologists taught that the first humans arrived in North America around 13,000–13,500 years ago by walking through an inland "ice-free corridor" between the Laurentide and Cordilleran ice sheets.
-
The "Eva of Naharon" Contradiction: In the early 2000s, divers discovered the 13,600+ year-old human skeletal remains of a woman nicknamed "Eva" in a flooded underwater cave system in the Yucatán Peninsula of Mexico.
Why Eva matters: Her remains dated older than (or matched) the Clovis timeline and were located thousands of miles south in Central America long before the northern inland ice corridor was passable. This proved conclusively that humans were already living across the Americas before Clovis, shattering the "Clovis First" model.
- The "Kelp Highway" (Coastal Migration Theory): Suggests that early seafaring peoples migrated southward by boat along the Pacific coastline, living off rich kelp-forest ecosystems (fish, shellfish, seals, sea mammals, edible seaweed).
- Submerged Evidence: When glaciers melted at the end of the Ice Age, sea levels rose ~100 metres, drowning ancient Pacific coastal settlements. The primary physical evidence of early coastal migration is now underwater.
- Two Ways of Knowing: Scientific archaeology (excavation, radiocarbon dating, testing hypotheses against physical evidence) sits respectfully beside Indigenous Knowledge (oral traditions, genealogies, presence "since time immemorial" / Wskitqamu). Neither invalidates the other.
💡 Key Archeological Takeaway
"Clovis First" is now recognized as scientifically incomplete. The discovery of ancient remains such as Eva of Naharon and Pacific coastal evidence demonstrates that Indigenous peoples have inhabited the Americas far longer and across more diverse migration routes than early textbook models claimed.
