Exploration of Oon Negro Cave

The video explores the discovery of Nia, a 16-year-old girl whose remains were found in Oo Negro, an underwater cave in Central America. Using radiocarbon and uranium-thorium dating, researchers determined she lived 12,000 to 13,000 years ago. Oo Negro serves as a unique time capsule, preserving remains of various Ice Age animals, including saber-tooth cats and giant sloths. The discovery offers insights into early human and animal life in the Americas. Researchers plan to reconstruct Nia's face, providing a glimpse into the appearance of one of the earliest known Americans.
