Wild dogs were domesticated 33,000 years ago

A group of Russian-led international archaeologists have discovered a skull of a supported dog dating back to 33,000 years in the cave of Siberian Altai mountain.

This is the earliest evidence to show that dogs have been domesticated by humans for a long time.

The domesticated dog skull dates back to 33,000 years in Siberia

By comparing muzzle size with the Greenland domesticated dog 1000 years ago, the size and thickness of the teeth with the wild wolf shows that 'this is a dog in the early stages of domestication. " Biologist, Dr. Susan Crockford, a member of the research team, said.

These dogs help humans fight against carnivorous wild animals and assist in hunting food.

But a special point is that this dog died in evolution. While humans continue to live in Altai through the last ice age without this dog. The reason may be that food becomes more scarce.
