Dogs
Transcript:
All domestic dogs belong to a single species that descended from wolves—despite vast differences in size, appearance, behavior and temperament among breeds.
While dogs first became domesticated tens of thousands of years ago, the breeds we know today are largely the result of selection for certain traits by humans over the past several hundred years. "We have an enormous amount of diversity within the same species, and we can rarely observe such diversity in nature. So it's a wonderful system to understand how evolution works within a short period of time."
Evolutionary biologist Laszlo Garamszegi of the Institute of Ecology and Botany in Hungary. He says that our playing with dogs is a key component of the human-canine bond.
