No, we couldn't fly. It takes more than wings to be able to fly: birds have a special cardiovascular system that is adapted to allow more efficient breathing, and a stronger circulation, to provide wing muscles with oxygen. Also (as others have mentioned) birds have special "hollow" bones: not actually hollow, but much less dense than our bones.

There are no flying birds that are the size of humans: the largest flying bird is the Andean Condor, and even it weighs only as much as 10kg (or 24lbs). Compare that with the ~150kg for humans.
So we'd need to lose a lot of bulk to be able to fly.

Finally, birds' wing muscles use a *lot* of energy. In humans, it is the brain that uses most energy. So there is an evolutionary choice between a large brain, and large wing muscles. We can't really have both; or - if we did - we'd eat a *lot* of high-energy food. And this would mean having to grow lots more food - quite possibly meaning there wouldn't be enough food to feed our current population. There would be less humans, and less humans means less advancement. So we would almost certainly be primitives.

No I do not think we would fly unless the wings were really big. Also, our bone density is much greater than birds. Plus since we are ot aerodynamic we would need a helmet to avoid getting tings in our eyes and break the wind.

In order to grow wings you would probably need to get some robotic surgery & get robot wings.

For many centuries, humans have tried to fly just like the birds and have studied the flight of birds. Wings made of feathers or light weight wood have been attached to arms to test their ability to fly. The results were often disastrous as the muscles of the human arms are not like a birds and cannot move with the strength of a bird.

No, we couldn't fly. We have a much greater bone density than that of flying mammals. The reason birds can fly is because their bones are "hollow" Ours are very heavy & therefore dictate that we stay on the ground. Even if we grew wings we still wouldn't be able to fly unless our physical body structure changed.

The answers about bone density are correct.

Additionally, wings are the equivalent of arms. To fly, people would have to give up arms and everything they are used for to be able to use them to fly. Would you really want to do that???

I think we could of fly but our wings got cut long time ago. If you want wings drink a Red Bull.

they would have to be pretty big wings to carry a human. and the only way to grow them would be altering human dna, or hundreds of thousands of years in the future we may have evolved to have wings.

no offense, but I doubt either of these things are ever going to happen, so no. We won't be able to fly. (except in planes of course)

Not me. And I'd be very interested in any other answers that could advise you on how to grow wings........

no, people can't fly even if we grow wongs
the shape of the body prevents us from doin' it. it's not aerodinamic. and the way we breath and our excretory system isn't either adampet to the conditions of flyin'.
