No heating. Almost no trees to burn. Months of frozen ground. So how did Ice Age humans survive winter?
Follow one Ice Age family through one winter, from the first snow to the first drip of the thaw. Along the way: a 25,000-year-old ring made from the bones of at least 64 mammoths, the 192 bone needles of Arctic Siberia, fires fed with bones, the strange danger of “rabbit starvation”, stone lamps that burned on fat, and the ancient DNA that reveals who made it through the coldest years, and who didn’t.
