400,000 years ago, humans could hibernate in winter

It has become known that 400,000 years ago man could hibernate in winter.

This is evidenced by the remains found by archaeologists from a mass grave in Spain.

Many mammals, such as bears, raccoons, and badgers, are known to hibernate in winter.

For these animals, hibernation during the cold season is the only way to survive the harsh frosts.

As it turns out, ancient humans could also sleep like this all winter long.

The new theory can greatly influence the scientific world and finally explain why it is so difficult for us to get up on the alarm clock.
