Notes on verification
Well-corroborated by multiple independent, reputable sources including Wikipedia, Britannica, Smithsonian, and academic/genetic research. Claim is carefully phrased as 'one of the earliest' rather than 'the first,' avoiding conflict with newer evidence of pre-Clovis sites like Monte Verde.
