Fish swim. Frogs hop. Birds fly. Well, not all birds. Penguins and ostriches, for instance, can’t spread their wings and soar. So then, why do they have wings? We asked paleontologist Jingmai O’Connor to help us find the answer.
Is there a question that’s got your tail feathers all in a twist? Send it to us at BrainsOn.org/contact and we’ll find a reliable answer – we promise not to wing it!
