You doubt it. Why? Because humans you feel are not capable by virtue of nature to produce and by produce I mean in that parlance, evolve, wings? Thanks, but it's been interesting to see how the discussion goes.
Like Mock Turtle said...
Nature (through evolution) has a way of providing for a need - we have no such need.
...he is right, YoursTrue.
Natural Selection is what provide all animals what are needed, and humans don’t need grow wings to fly.
And there are lot more to bird’s anatomy and physiology that enabled flight for some birds (and not for some others) that humans don’t have.
For instances. A bird’s shoulders and limbs (wings) are anatomically built and biomechanically move differently to human’s shoulders and limbs (arms). Humans don’t have lightweight skeletons and don’t have cavities connected to the respiratory system. Humans also don’t grow feathers.
The only mammals that can fly are bats, and we are nowhere that closely related to bats.
And even with wings, not all birds can fly, for instances, emu, ostrich, penguin.
The 3 examples above, have more powerful legs through Natural Selection. With the emus and ostriches can fast to avoid natural predators, while penguins cannot run on land or on ice, but are superb swimmers.
But there are no needs for humans to have wings, because they are naturally inclined to fly.
Although winged humans or winged angels may be interesting fantasies, but in reality, they are merely pipe dream or worse, delusions.
