How Did Humans Survive an Ice Age?

The planet ran about six degrees colder, ice sheets buried huge stretches of land, and this wasn't a rough winter — it lasted roughly ten thousand years. No heated buildings, no insulated jackets, no trucks bringing in food from somewhere warmer. Just people, ice, and whatever they could build with their own hands. This video breaks down the five real systems that got people through it: fire tended like a lifeline, tailored cold-weather clothing sewn with eyed bone needles, circular shelters built from dozens of mammoth bones, food deliberately stored and preserved ahead of winter, and the shared knowledge passed person to person that made all four of the others possible. Lose any one system, and the rest stop being enough. This is Way Back Explained — the small, human questions history books usually skip.
