Dog expert Mark Derr, author of How the Dog Became the Dog (available now) has made a career out of exploring the dog/human relationship, debunking myths through scientific research and canine journalism. In recent essays and interviews with The Wall Street Journal, Salon, and NPR, Derr sheds light on the evolutionary history of man's best friend.

Below, Derr discusses the latest scientific findings that challenge the consensus model of dog domestication with WSJ's Christina Tsuei.

In a recent interview with Salon.com's Emma Mustich, Derr delves into the co-evolutionary development shared between humans and dogs and rev
