DVD Evolution: Constant Change and Common Threads

In this video, we learn how the art of manipulating phenotypes through selective breeding in dogs is used to manipulate the gene pool. Over 10,000 years ago, wolves started to live among humans, and the selective breeding began. By actually choosing which dogs have the desired traits that are needed to perform tasks such as hunting, herding, guarding and many others, humans have been able to manipulate and determine the traits of those down the bloodline. The same hold true for charactaristice such as size, coat and color, as well as many other traits or charactaristics.
