The grey wolf has been transformed into what we, today, call a dog. After years of traveling with humans, the wolf began to change and became adapted and tame enough to socialize with humans. The environment it was placed into was one of the causes for change, and another was the role it played for humans.

The most likely scenario for wolves beginning to coexist with humans is that a human hunting party came across a very young wolf cub and decided to take it with them. The wolf cub would have been very puppy-like at an early age. The reason that humans would ever take a wolf cub is because the cub would be seen as a valuable resource to humans back then.

The humans would share their food with the cub and protect it from being hunted by outside animals, but they would also use the cub to keep them alive by having it track down prey for food. Also, they would probably watch to see if the cub sensed danger in the nearby area so then the hunters could avoid it, too.

However, the hunters would not keep all of the wolves that grew up from the cubs they had. Keeping a wolf that became overly aggressive towards them, or if it had little practical use, would have been both pointless and dangerous to their group. They most likely would have killed those types of wolves or left them behind to fend for themselves.
