Disabilities are mainly the cause of mutation, (trisomy) of chromosomes. Being disabled would reduce your chance of sexual reproduction, and therefore limiting you from passing on those genes. Therefore I don't think it would evolve humans because we are not all born with disabilities, but we have an apparent inefficient way of performing meiosis of fetal cells. Thats what I think could be developing to reduce the amount of disabled offspring are produced.
Who knows, nothing we can do about evolution anyways.

Very true, what we create as humans that arent natural to aid our survival as a social tool is a "meme". These memes are limiting the way natural selection actually selects.
