Discovery Channel - Dogs: The Ultimate Guide

At times, dogs appear to move and react like wild animals. Yet they are, by definition, domesticated.

But for all their variety of appearance, all dogs are simply mutations of their closest ancestral relative… the wolf. How did the dog come to be so successfully domesticated from its wild ancestors? Dr. Rodney Honeycutt discusses the genetics of domestication and some of the special qualities of the dog, such as its phenomenal senses of hearing, smell, and taste.
