How Did Ancient Humans Survive the Ice Age?

No heater. No zipper coat. No insulated walls. So how did ancient humans get through Ice Age winters when even the yearly average was below freezing? We follow one (made-up) family, Ugg's, through a single winter, from the first frost to the first spring flowers, and everything they do comes from real Ice Age sites. Bone needles and fur-in, fur-out parkas, houses built from the bones of dozens of mammoths, fires fueled by bone, frozen storage pits, and a strange food rule: in the cold, lean meat isn't enough. You need fat.
