Where did they develop the ability to fly? Did that occur once, with all birds, or did a few species develop that ability before others? A: Birds did not evolve from reptiles. Both have developed wings at roughly the same time - about 300 million years ago - and as one of the most notable examples, a bird's wings are composed of feathers that are not directly attached to the bird's back, and develop from skin tissue (the dermis) instead of directly from cartilage. According to Wikipedia: Birds are the only group of tetrapods to have evolved wings. A related fact is that every bird is a reptile, which is probably why you didn't cite a specific example. A more comprehensive list of winged species can be found here. A: The first known animals with wings were probably the Archaeopteryx. [Source: Hamilton & Zahn (2008), Archaeopteryx: an icon of evolution]. Now, this isn't exactly the earliest example of a winged creature, because the Archéopteryx is a transitional form between dinosaurs and modern birds. The first species with a definitely recognisable direct ancestor to modern birds is Archaeopteryx lithographica, as evidenced by the discovery of a partial skeleton in 1991. Now, this doesn't mean that Archaeopteryx was the earliest bird, because there's a chance that it's just that you have a very good example of a winged dinosaur. In fact, the results of the 2004 paper that disproved Archaeopteryx as the earliest bird turned out to have been severely underestimated. There's only one known specimen, a juvenile, so that's about as good as we can get. A: Yes, humans have the ability to fly. That's a pretty obvious thing to say, unless you are talking about inanimate objects or inanimate objects that fly. Wings only evolved in those species that needed to fly. Birds, bats, etc., all evolved wings. The evolution of flight in dinosaurs occurred much later. Evolutionary time scale: Q: Matching link: background color
