    That's 95% for twins. The same genetic information.

    Nobody is arguing that it is not genetic. It clearly is. Twins have the same genes, they are both very likely to be autistic. That does not mean that their children will be autistic.

    Am I missing something here? I read this as twins being included but statistically being quite a small proportion of the overall sample.

    I agree that autism has been around for as long as humans have been alive. Furthermore, I'd describe it as a regressive trait, not an 'evolution'.

    Humanity's success is tied to being able to live in cities - huge groups of unrelated people working together in close confines. The selective pressure is for the super-social, not those who get totally stressed out around other people. Dogs and cats have been under the same evolutionary pressure, becoming docile and social over time.

    I'd say autistics are more likely to resemble the pre-social human brain.

    I agree with BrokenBoy here. It seem kinda elitist.

    To be honest, I don't really believe in evolution. There isn't enough evidence about all this "rift valley" stuff for me to believe in it.

    this subject is likely gonna cause problems. anyway, if it was an evolutionary measure, then its clearly not a good one, as it is loaded with many, many, many, issues that will be nothing but a huge burden in their lives, with little to no useful benefit that non autistic people can easily replicate.

    Yes. They are not saying that the parents were 87% autistic. What they are saying is that is the chance that autism is related to the genetic material as opposed to environmental factors is extremely high.

    They are not saying because autism is inherited that it was inherited from an autistic person.

    "Because ASD is rare, estimates of heritability rely on few families with more than 1 affected child, and, coupled with the time trends in ASD prevalence, the heritability estimates are sensitive to the choice of methods. The method initially chosen in the previous study led to a lower estimate of heritability of ASD." (Form the abstract)

    The study is simply not asking the question, "do autistic people have autistic children". It accepts the statistical fact that very few members of any family are autistic. The study is trying to do the difficult task of determining whether or not it is genetic as opposed to environmental. Difficult because it is not a clear pass down dominant v. recessive like, let's say, hair colour.

    Autism is a cascade of interacting genes which need to fire in unison for the condition to be realized. This is why it is free from selective pressures.

    It seems we were both wrong. According to several other sources such as the one below neither of our interpretations above are correct. It's the 0.83 that is the significant figure. 95% is their statement of certainty it seems. The heritability quoted in that most recent study is 83%.

    No. Mutations never produce a stronger creature.

    I disagree because pure breeds in animals tend to be more prone to health problems than a non-pure bred.

    I believe in autism just being another brain "operating system" so it is something that has happened to exist alongside the allistic "operating system". We're only becoming more aware of autism now because of advances in understanding in human behaviour, etc. That doesn't make it an evolution at all.

    For some reason this logic is reminding me of the poor use of the word "evolving" in the Pokémon franchise. Seriously, Pokémon do not evolve, they do metamorphosis.

    IMO, the people who're truly on the spectrum are being short-changed by the over diagnosis of Autism, HFA & Aspergers. Both my son and I are on the spectrum, me more than him. I know it when I see it and I also know when a person has been wrongly diagnosed. Usually, the misdiagnosed people have been enabled to be jerks from bad parenting. The misdiagnosis of Autism is like a free pass to continue to be jerks and I've seen this in both children and adults. And so, the more misdiagnosis occurs, the lines of what true Autism is, are blurred. Thus, morphing Autism into something different than what it is / was.

    About a decade ago a prominent radio host in the US, Michael Savage, went on a rant on air about how autistic people are just jerks whose parents paid a psychologist to put a label on being a jerk so they could get a free pass in life, and how autistics are just spoiled brats who need a few good spankings. The audio went viral and a lot of people were angry, but then there were people who totally agreed with Savage. I know I'm not the only one here who had a childhood full of adults telling me what an arrogant bunghole I was and how I needed to be put in my place. My dad could never figure out why the beatings never had the desired effect. Even when I was well into my 30s my dad would yell at me for being "lazy".

    Are you sure? In biology class, I learned that a mutation is either beneficial, neutral, deleterious (makes organism's life more difficult), or lethal.

    However, the mutations that result in Autism are neutral due to Autism being a spectrum.

    I cannot accept base autism* as being the product of genetic mutation anymore than sinistrality is.

    *Autism without complications.

    Here is what a quote from this Wikipedia article on the heritability of autism.
    So, yes, yes it does. Also, it can be caused by drugs used by the mother during pregnancy. These drugs can either be legal or illegal drugs, too.

    That sentence from Wikipedia doesn't actually say anything definitive, so I'd be wary of drawing conclusions just from that.
