The Wolf that became Domesticated
Some form of wolf still exists today in Europe, Asia, Australia and the entire American continent. These provide evidence that the wolf can and did live in the close proximity with humans and become domesticated.
Along with the Bronze Age people, it appears that as the wolf spread from the North to the East over the Northern Hemisphere. Many of today’s pure-breeds can be traced directly back to wolf ancestry and most modern dog breeds are also genetically similar to the wolf.
