14,500-Year-Old Site's Age Questioned
19 Mar
Summary
- Monte Verde's age re-evaluated, potentially much younger than 14,500 years.
- New study suggests soil erosion caused previous misdating of the site.
- This finding reignites debate on how and when humans first reached the Americas.
A significant archaeological discovery may be altering the timeline for human presence in the Americas. For decades, the Monte Verde site in southern Chile, purportedly dating back 14,500 years, challenged the prevailing Clovis-first migration theory. This theory posited that humans arrived in the Western Hemisphere via the Beringia land bridge around 13,000 years ago.
A new study published recently in Science proposes that Monte Verde's age was overestimated due to soil erosion. Researchers suggest the site may actually be between 6,000 and 8,000 years old. This re-evaluation could re-establish the Clovis culture's migration timeline as the primary explanation for early American settlement.
The original excavation of Monte Verde in 1977 by Tom Dillehay had placed it as an outlier, suggesting pre-Clovis populations in South America. However, the recent independent survey by Dr. Todd Surovell and his team aims to correct this anomaly. Further examination of other pre-Clovis sites across the Americas is now encouraged to refine our understanding of this complex history.
