WHICH CAME FIRST, THE DOG OR THE WOLF?

Science Illustrated - - ASK US -

What? What’s the prob­lem? It’s ba­si­cally the ex­act same ques­tion. Yet every­one knows dogs are de­scended from, in­deed are still a sub-species of, wolves. And no one seems to have a prob­lem with that? Both species – Ca­nis lu­pus and

Gal­lus gal­lus – ini­tially ben­e­fited from hang­ing around near hu­man pop­u­la­tions, be­cause we got them ex­tra food, one way or another. Even­tu­ally we no­ticed them, caught some of them, bred them, and the rest is his­tory. How­ever, that there are hun­dreds of breeds of dogs and hun­dreds of breeds of chicken is surely no co­in­ci­dence. The way both species can pro­duce such rad­i­cally dif­fer­ent phe­no­types from the same set of ge­netic code is prob­a­bly key to the rea­son we were even able to do­mes­ti­cate them in the first place.
