Throwing a raw bear pelt over your shoulders wasn't a survival strategy; it was a death sentence. In this video, we uncover the bizarre biological loopholes and prehistoric engineering behind ancient Arctic survival: Brain Tanning: How Ice Age humans used mashed animal brains and smoke to stop hides from rotting or freezing solid. The 50,000-Year-Old Denisova Needle: How tiny bird-bone needles and shredded reindeer spine tendons (sinew) created airtight, waterproof seams.
