How Did Ancient Humans Actually Survive Deadly Winters?

How did ancient humans survive deadly winters with no heating, no glass windows and not even a match? About 20,000 years ago, Ice Age people on the plains of Ukraine and Russia lived through winters around minus 4°F, and this is how they did it.

We start with the cave myth and why it is mostly wrong. Then we look at the real evidence: lice DNA that dates the first clothes, the oldest eyed sewing needles, shelters framed with mammoth bones at Mezhyrich and Kostenki, the debate over burning bones for fuel, why eating only lean meat can kill you (rabbit starvation), the bold and disputed idea that early humans hibernated, and the ancient DNA that shows who made it through the coldest part of the last Ice Age and who vanished. Some parts of this story are solid evidence and some are educated guesses. The video tells you which is which.
