New study pushes back human arrival in Americas

Key Points

1. 1
   A new archaeological study suggests the Monte Verde site in Chile is significantly older than previously calculated, potentially dating back over a decade earlier.
2. 2
   This revised timeline challenges long-standing theories that humans arrived in North America via Beringia between roughly 13,400 and 12,800 years ago (Clovis culture).
3. 3
   The findings imply human populations may have settled the Americas from South to North much earlier than established models predicted.
4. 4
   "Again" is emphasized by multiple sources as this study renews debate that was already unsettled in previous decades.
