As it turned out, in the early days, people dealt with cold winters with the help of the caves and hibernated just like bears. The New York Post writes about new research.
Recent studies have shown that our Neanderthal ancestors had to slow down their metabolism to survive the cold winters in Europe. However, they slept long in the winter due to food shortages.
"Hibernation would be the only solution for them to stay in the cave for months in cool weather," said one of the researchers.
