Story summary

A study led by Todd Surovell dates Monte Verde, Chile, at 4,200 to 8,200 years ago, challenging the 14,500-year estimate and its pre-Clovis placement.
Geological factors may have mixed older materials with younger sediments, questioning the original dating.
The revised timeline shows Monte Verde should not be treated as a fixed reference for migration models.
The study does not rule out earlier human presence in the Americas.
