Human Settlement In The Americas May Have Occurred in the Late Pleistocene
Scientists have long debated about when humans first settled in the Americas. While osteological evidence of early settlers is fragmentary, researchers have previously discovered and dated well-preserved prehistoric human skeletons in caves in Tulum in Southern Mexico.

The researchers’ isotopic analysis dated the skeleton to ~13 k BP, or approximately 13,000 years before present. This finding suggests that the Chan Hol cave was accessed during the late Pleistocene, providing one of oldest examples of a human settler in the Americas. While the researchers acknowledge that changes in climate over time may have influenced the dating of the skeleton, future research could potentially disentangle how climate impacted the Chan Hol archaeological record.
