Nautilus - How We Really Tamed the Dog 21min

Cuteness would be as well, perhaps with gentle eyes, and a curly, bushy tail that wags in joy in anticipation of your appearance. ... You needn’t bother trying. Lyudmila Trut and Dmitri Belyaev have already built it for you. The perfect dog. Except it’s not a dog, it’s a fox. A domesticated one. They built it quickly—mind-bogglingly fast for constructing a brand new biological creature. It took them less than 60 years, a blink of an eye compared to the time it took for wolves to become dogs. They built it in the often unbearable negative 40 degrees Fahrenheit cold of Siberia, where Lyudmila and, before her, Dmitri, have been running one of the longest, most incredible experiments on behavior and evolution ever devised. ...
