The 12,000-Year-Old Girl Found Deep Inside A Flooded Cave — And The DNA Discovery That Changed The Story Of The First Americans
How Naia got to the bottom of Hoyo Negro is genuinely uncertain.
The most parsimonious explanation, given the evidence available — the absence of burial goods, the scattered and disarticulated nature of her remains, the presence of animal bones from animals that fell into the pit — is that she fell.
The entrance to the pit chamber, from the cave passages above, may not have been visible in the darkness, or she may have been exploring the edge of it and lost her footing.
But this explanation, while plausible, cannot be confirmed.
