How did feathers evolve? Not something I’ve ever really considered, but now that you mention it, I don’t know of one of those ape-to-human evolution images for feathers. So, how did they?
Feathers are wonderfully intricate and versatile features. Often considered delicate, they offer a robust ability to camouflage, impress potential mates, waterproof, insulate, and assist in flight.
Quite a marvel of attributes they can bring to a species and, as Carl Zimmer explains in this animation, it all started with seemingly “accidental physics” that took place 50 million years ago.
