Underwater Mexican Cave Yields Ancient Skeleton
Divers found an ancient skeleton in a Mexican cenote believed to be several millennia old. The underwater cave discovery could reshape understanding of early human habitation in the Americas. Mexico's cenotes have become increasingly important archaeological sites, revealing new chapters in pre-Columbian history.
The Yucatán Peninsula's submerged caves and cenotes are a treasure trove for paleoanthropologists, yielding some of the oldest and most complete human skeletons in the Americas. These natural sinkholes, which were dry and accessible during the last ice age, became flooded around 8,000 years ago, preserving the remains of early inhabitants and extinct animals like saber-toothed cats and giant ground sloths. One of the most significant finds is "Naia," the skeleton of a teenage girl who lived almost 13,000 years ago. Discovered in 2007 in a pit called Hoyo Negro, her remains are considered the "oldest, most complete and genetically intact human skeleton in the New World." Analysis of her bones revealed a life of hardship, with evidence of nutritional stress and a fractured arm. The Chan Hol cave system, near Tulum, has also yielded multiple prehistoric skeletons, including the "Young Man of Chan Hol," dated to at least 10,000 years ago, and a woman from 9,900 years ago who showed signs of a bacterial disease and several severe head injuries. These discoveries provide a glimpse into the challenging lives of the first people to inhabit the region. These ancient skeletons possess skulls that are narrower and have different features than modern Native Americans, leading to theories of multiple, distinct early migrations to the Americas. However, DNA analysis of Naia showed a genetic link to modern Native Americans, suggesting they both stem from a single source population that migrated from Siberia. This complicates earlier models of how the continents were first populated.
