Maybe, I mean they could evolve to become these pigs with wings, so anything's possible. Or, they could not evolve and have avian DNA put into their DNA, it could happen. But we don't know for sure if they will, but anything's possible
At the moment pigs cannot fly, but in the future there may become a breed that could maybe fly.
A sentence could be: I will give you money when pigs fly
you can never fly cars only in the future when everything has been invented like when 'pigs fly'
no they could not they would need to have a much larger chest to support the wings and they are to heavy to have the strength to fly pigs could fly if they evolved all of these things but then it wouldn't be a pig
You cannot fly.
Umm... well, I wouldn't.Besides, pigs DON'T fly. xD
Pigs cannot fly, and never will be able to fly. So the response that something will occur "when pigs fly" is emphatic skepticism that it could ever happen.
HECK YEA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
