Re: autism [Warning: hacky pseudoscientific musings ahead]
I can't decide whether the high incidence of autism is an environmental genetic defect, a partial but flawed adaptation to a verbal language based society, or a primeval throwback to a time when overactive senses were less of a deficit ... Or there's my other theory : Neuropathologies that can occur in individuals of otherwise normative intellectual capacity occur again and again because they are an adaptation of the human superorganism. What I mean is ... As an individual , my survival may be reduced by a pathology like autism, ADHD, schizoaffective , bipolar, hypomania, or neurosis such as obsessive compulsive ... But society having those unique individuals is adaptive to the human super organism. If we were to prune these "pathologies" from our gene pool, we would lose so much of the innovation that is so key to our survival. Of course if this is adaptive it would have been thousands of years ago, in ancient hominids ... And what we call neuropathology is only echoes of that super organism model. Like ants and termites have different classes that are physically different, maybe humans have different brains for different abstract situations. If so then neurodiversity might be a crisis for the individual, but a potential success for humanity as a whole. Anyway ...
