We now know that many dinosaurs had feathers; the question is, why? They couldn't fly, but for some reason, they developed fluff that eventually became feathers. There must have been some benefits from the plumage that eventually helped birds to fly. One of my favorite science writers, Carl Zimmer, explains how this may have happened. -via Geeks Are Sexy
