Скачать или смотреть Analysis of Naia- Most Complete Paleoamerican Skeleton-Solves an Evolutionary Mystery

Deep beneath the jungle floor of the Yucatán Peninsula lies a submerged vault known as Hoyo Negro (the Black Hole). In 2007, cave divers discovered a near-perfectly preserved skeleton of a teenage girl they named Naia.

Naia lived at the end of the last Ice Age, in a world of giant sloths and saber-toothed cats. Her tragic fall into a dark, underground pit became a time capsule that would eventually revolutionize our understanding of human evolution.

For decades, scientists were puzzled by the "Ancient American Mystery"—why did the earliest skeletons look so different from modern Native Americans? Was there a "lost race" that vanished before modern tribes arrived?

In this video, we explore Naia’s incredible story:
The harrowing details of her final moments.
How a "liquid lid" of fresh water preserved her bones for millennia.
The DNA breakthrough from a single tooth that solved a continental mystery.
Why human faces change over time (Phenotypic Plasticity).
