The gray wolf 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 they were placed in was one cause of the change, and another was the role they played for humans. The most likely scenario for wolves to begin to coexist with humans is that a group of human hunters come across a very young wolf cub and decide to take it with them. The cub looked very much like a puppy from a very young age. The reason humans would ever take a wolf cub is because the cub would then be seen as a valuable resource to humans. The wolf cub would become a sort of tool for humans because it is a better tracker, has sharper senses, and is faster than humans. The hunters would have thought that they and the wolves were both hunters and hunted in packs. Humans would share their food with the cub and protect it from hunting by outside animals, but they would also use the cub to keep it alive by having it hunt down prey for food. Additionally, they would likely monitor if the wolf senses danger in the surrounding area so that hunters can avoid it as well. However, hunters would not keep all the wolves from the pups they had. Keeping a wolf that had become too aggressive towards them, or had little practical use, would have been both useless and dangerous to their group. They would most likely have killed these type of wolves or left them to fend for themselves. Hunters would have chosen semi-tame wolves and those with the most desirable traits and abilities and bred the two together, repeating the process until what today resembles a dog. The first bones discovered that ...... middle of paper ...... will also continue to adapt as they have for centuries, as long as people and the environment they live in continue to change . The common dog will always trace its roots back to the unique wolf pup that was taken in by humans so long ago.
