(Christina) They are warm, fuzzy beings that come in many different shapes and sizes, yet they all sense our emotions and thrive in our company. But they are also descended from wolves, fierce and elusive social predators. How did dogs become so integrated into human society? And how can we reconstruct any species’ prehistory? In the first installment of our new Doggy History series, we examine several theories about how dogs left the wolf pack and became part of ours instead, and find out that humans have been blaming it on the dog pretty much forever.
