How Did Ancient Humans Survive Freezing Winter?

Negative forty degrees. No coat, no fire, no walls. You'd be dead in two hours. So how did ancient humans survive entire Ice Age winters on the open plains of Europe, without anything we'd recognize as real technology? This video breaks down the actual survival system that got modern humans through the last glacial maximum, from the bone needles that made fitted, tailored clothing possible, to the mammoth-bone dwellings built on treeless steppe, to the deadly mistake that could undo it all in minutes. We look at archaeological sites in Ukraine, Russia, and the Czech Republic, and what 40,000-year-old sewing tools reveal about how our ancestors engineered warmth from scratch. Every claim in this video is backed by published research. Sources below. Sources: The Evolution of Modern Human Clothing — Gilligan, I.
