Around this time, not having the same sharp teeth, tearing jaws or speed as dogs, humans were isolated and vulnerable. They seem to have “adopted” the canids that helped protect emerging hunting stations and year-round settlements. These ancient canines must have acted as early warning alarm systems, and, in times of famine, they could have been a food source, or a source of food through the animals they killed and brought back to human settlement areas. This ancient union of man and dog led to the oldest and most effective hunter-killer team on earth. In return, dogs got companionship, protection, shelter, and a more stable or diversified food source.
