  • Evidence from the 1990s shows human habitation in Monte Verde, Chile, dating back to 14,500 years ago - a millennium older and much further south than what was previously thought to be the first people in the Americas. How they got there is open to debate.

  • Another claim for human settlement in the Americas is the Topper Site in South Carolina, dating back to about 15,000 BP.
