I’ve always had an interest in domesticated animals as examples of the power of genetics. Darwin himself, saw the ability of breeders to create changes in pigeons and other domestic animals as a mechanism for the changes that take place in nature. Just as humans mold animals via controlled breeding, so, too, could circumstances in nature effect which animals were able to breed and with whom. Of course, selection isn’t only driven by strict practicality whether it be by the randomness of nature or the whims of man, which leads us to these five oddballs of the cattle kingdom.

A new paper published this week in the journal Evolution details how a group of scientists led by Arhat Abzhanov of Harvard and Bhart-Anjan Bhullar of the University of Chicago have unraveled the genetic changes that transformed the skull of a theropod dinosaur into the unique beak of modern birds.
