Biological evidence challenges Clovis-first migration theory. DNA study indicates Native Americans' mitochondrial and nuclear DNA split from the rest of humanity roughly 35,000 years ago, contradicting the Clovis-first model Algonquian-speaking nations carry the X2a haplogroup linked to the far eastern Mediterranean Some Patagonian tribes show Southeast Asian DNA strains
DNA shows Native Americans' DNA split from humanity ~35,000 years ago—contradicting Clovis-first. Algonquian speakers carry the X2a haplogroup linked to the far eastern Mediterranean. Carl Johansen identified 472 species that couldn't have crossed Beringia yet appear in the Americas. Parasites unable to survive cold climates also turn up in American sites—hinting at transoceanic contact. 🧬
Key Facts
- DNA study indicates Native Americans' mitochondrial and nuclear DNA split from the rest of humanity roughly 35,000 years ago, contradicting the Clovis-first model
- Algonquian-speaking nations carry the X2a haplogroup linked to the far eastern Mediterranean
- Some Patagonian tribes show Southeast Asian DNA strains
- Parasites found in ancient human intestines cannot survive cold temperatures, yet appear in sites across the Americas, implying transoceanic rather than Bering Strait crossings
- Carl Johansen's work identified 472 species of plants and animals that could not have migrated across the Bering land bridge with humans but appear in the Americas
- Analysis suggests the proposed ice-free corridor lacked the size and vegetation needed to support human food sources for migration
