How Did Ancient Humans Survive Winter Without Houses?

You can live through a night at minus twenty. People did it for forty thousand winters. What you cannot live through is being wet at plus five. That is the part nobody tells you about cold — and almost everything else you picture about surviving winter in the deep past is wrong too. The fur over one shoulder is a blanket you are carrying, not clothing. The fire does not warm the air. The cave was probably already taken. This is what actually kept people alive: a needle with a hole in the blunt end, a closed cuff, a small dark space with other bodies in it, and the fat that everyone else throws away. Plus the strangest piece of evidence in the whole story — a louse that can tell you when humans started wearing clothes. Two notes on the arguments behind this. The date for the first clothing comes from lice genetics, not from any surviving garment, and the estimates range from about 80,000 to 170,000 years ago depending on which genes are used. And while the short, wide Neanderthal build fits what cold does to a body, some researchers argue that activity levels and mountainous terrain explain part of it too. The Mezhyrich bone structure figures follow the 2025 re-dating by Chu and colleagues.
