Now this is pretty exciting. Archeology, scuba and cave diving all rolled into one.
Inside a cave so deep and dark it's called Hoyo Negro, or Spanish for
"black hole," divers are transporting a 12,000-year-old skull for 3D
scanning. The skull belongs to one of the oldest and most complete
skeletons ever found in the Americas.
The skeleton, belonging to a 15- or 16-year-old girl whom scientists
have named Naia, helps solve a long-running debate on what early
Americans looked like. Naia's narrow face and prominent forehead look
nothing like Native Americas, but her DNA markers prove their related
At the time of her death at the end of the ice age, the caves on the
Yucatan peninsula were likely dry. Since then, rising sea levels have
flooded the caves. Divers first discovered Naia's bones, along with the
bones of extinct animals like saber-toothed cats and giant ground
sloths, in 2007. Her bones have since been moved after unauthorized
divers entered the cave.
