The origin of “man’s best friend” isn’t entirely clear. Scientists agree that dogs evolved from wolves, but we don’t know exactly how or when this transformation happened.Still, researchers are getting closer to understanding how wolves became the dogs we know today. Dogs were the first ever species to be domesticated, and it may have happened largely by mistake.Most scientists assume the process began with wolves following human hunters and eating food scraps left behind. The more docile wolves were, the more likely humans were to tolerate them and leave them food.Over generations, the friendlier animals would have had an advantage. Eventually, these wolves became increasingly comfortable around humans, while their diets also began to change.Dogs’ diets evolved to become more starch rich, along with humans. As farming became more widespread and food became more accessible, it became easier for these animals to live alongside us. And as humans and early dogs spent more time together, they slowly developed a special bond. What may have started with a few scraps of food eventually became one of the closest relationships between humans and another species.For years, scientists believed dogs were domesticated independently in two separate regions. Asia and Europe were both thought to have developed their own dogs, resulting in distinct populations between the two areas.But new research suggests the story may have been different. Scientists now propose that dogs came from a single population of wolves around 40,000 years ago.About 17,000 years later, these early dogs became separated. Some ended up in Asia, while others wound up in Europe, eventually contributing to the different dog populations that developed across the two regions.So, before dogs were our loyal companions, they were wolves living alongside humans and taking advantage of an unexpected food source.And that ancient relationship may have started with something as simple as a hungry animal following a hunter.So next time your dog begs for food, don’t be mad. They wouldn’t be around if they never did.
