Virtually impossible. To even begin to evolve in that direction, our species would need to be subject to some sort of selective pressure that would favour the development of proto-wings, which we're not. To evolve useful wings, we would also need to become smaller, evolve honeycomb bones and lose most of the muscle mass in our legs and nearly all our teeth just to be light enough. If our wings evolved from arms, we would become much clumsier and lose the benefit of our hands. If they grew as separate limbs, we would need to reorganise our skeleton and muscle structure radically over thousands of millions of years.
