According to an article in Discover magazine (dated November 14, 2013), dogs were likely domesticated from wolves in Europe tens of thousands of years before anyone originally thought.
Previous findings had suggested that canine domestication was linked to humans’ discovery/invention of agriculture. But that was under 10,000 years ago, suggesting that dogs might be a relatively recent addition to the animal kingdom. The new research posits the opposite: that wolves started dogging it up tens of thousands of years earlier, while humans were still mostly hunter-gatherers.
An interesting idea, especially for those of us whose canines are an integral part of our families.
