Wolves are the perfect example of a family unit – they’re loyal, loving, and work together to survive. These traits aren’t a recent development; they’re actually millions of years old!

An international research team has reported specimens of an ancestral wolf, Canis chihliensis, from the Ice Age of north China (~1.3 million years ago), with debilitating injuries to the jaws and leg. The wolf survived these injuries long enough to heal, supporting the likelihood of food-sharing and family care in this early canine.

When it comes to wolves, it really is all about family.
