Naia is a 12,000 to 13,000-year old human skeleton of a teenage female that was found in Mexico. The bones were part of a 2007 discovery of a cache of animal bones in an underwater chamber called Hoyo Negro (Spanish for "Black Hole") in the Sac Actun cave system. The remains have been described as the "oldest, most complete and genetically intact human skeleton in the New World".[2] Her name is derived from a type of water nymph in Greek mythology - the Naiads.
