One of the earliest known people to live in the Americas, a girl dubbed Naia who roamed the Yucatan Peninsula about 12,000 years ago, was slender and short and endured hardship, childbirth, and death all by age 16 or so. Naia’s remains were found in an underwater cave so huge, deep, and dark that researchers named it Hoyo Negro or Black Hole. Researchers have determined she was aged 15 to 17 when she died, which probably happened when she fell into Hoyo Negro. At that time, the cave was not underwater because sea levels were considerably lower, by as much as 300 feet (91.4 meters).
