I can recall that being the belief that I had, and that my then contemporaries had. For us, a genetic mutation was a fully-developed change of some kind. If it was beneficial, the organism in question thrived and his non-mutated brethren waned. Otherwise they died off because fully-functional bats wings wouldn't do much good to a human who was too heavy to lift off, and who otherwise would be burdened by them.
The lack of understanding of the fundamentals of evolution seems widespread in my experience. And it is one of the things that helps creationists cling to their dogma. If your understanding of evolution is so warped, then creation sounds like the obvious option and evolution can only be a clever distraction from Satan. How could otherwise rational beings believe it???
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."

I have to think it is intentional. Creatards could not be that stupid by accident.

I think fully-functional bat wings would probably be a neutral mutation for a human. True, they don't have much use (other than being epically cool), but they don't exactly inhibit the human or prevent it from living normally.

Anyone who has ever visited a hospital museum of a certain type can say that freaky things do get born and mostly end up in large pickle jars for people to marvel and feel queasy at.
But sometimes they live.
And you must give kudos to these two or one or whatever you call them/her.

I love the one with four spines. That's awesome.
Regardless, I will believe in evolution when a cat gives birth to a dog.

I'm hesitant, given that you've included the term "fully-functional" to describe a mutation which is not functional, and certainly not functional for flight. However, the most probable mutation resulting in bat-like wings would be similar to syndactyly of the feet or hands. Not only would such a mutation be somewhat dysfunctional, it would make it extremely hard to get a date on a Saturday night.

I meant fully-functional in that they could extend and even be flapped. You're right, though. If they're not functional for flight, they can't properly be described as fully-functional.
I don't agree that they'd necessarily be a neutral mutation. On the positive side, maybe chicks would dig guys with bat wings growing out of their upper back. On the other side, it's additional body mass that would have to be maintained and which would slow the person down when running from a sabre-toothed tiger (who might just be "in a mood for some wings").

I would think that the split between the human and bat lineage would have occurred before the development of wings so I doubt that it is possible at all.
If they had shared a lineage after that then I think genetically it would have been a possibility.
