Skeleton from Mexican cave sheds light on first Americans
Scientists tracing ancient origins of the first Americans use DNA from a teenage girl found in the submerged Hoyo Negro cave near Tulum. The nearly complete skeleton, dated about 13,000 years ago, supports a theory that early migrants arrived from Asia via a now submerged land bridge. The discovery, made by divers who named the skeleton Nala, offers insight into migration routes and early human life in the region.
