Dont you think that seems like a staggeringly high number for boys to have the same type of mental disorder?
And dont you think its very odd that boys have it 5x more than girls?
There was a pretty interesting study I read about from a Ted talk, I wish I could find it again. But it essentially talked about how Autism might be influenced by the information age. Since autistic children are generally less sociable but usually have stronger pattern recognition and information processing skills. The hypothesis was that because information now is sent without a lot of social cues, that those areas of the brain are diminishing while the areas that handle just the actual information are growing. Makes it really interesting when you combine that thought with the Ted talk about how society is "evolving" along the same patters of biology.
At first there were early "colonies" of cells, that worked loosely in cooperation, but with very primitive links. Just like early humans worked mostly by speech/signals, and in small groups.
Then those cells formed plants and other basic lifeforms, and their communication was driven by "slow" (Comparatively) but well defined chemical and receptor systems, that continually became more and more advanced. I'm a retard in bio, but I'm guessing our hormone/endo system is far more advanced than a say, a plants chemical equivellent--regardless he made points showing how chemical receptor systems went from very simple to highly complex and this growth allowed the life forms to become much more complex. Just like humans began to use writing and reading as forms of communication which allowed societies to become larger and more complex, and as the methods of writing and reading became more complex/faster (Paper, roads to carry paper, printing press and eventually systems dedicated to communication ect.), it allowed societies to grow larger and larger. (dark ages showed how societies complexity is hinged so directly on this, just like a life forms complexity is hinged on communication with other parts of itself.)
Then the advent of the nervous system came--and that allowed life to communicate very quickly, and it also allowed things to be passed down beyond just the genetic level (Teaching ect). This lead to an explosion of more complex life and really. In humans, he compared this to the advent of the telegraph (Simple nervous system) and eventually growing into the internet, and the internet even growing to be more portable/ubiquitous/accessible (Smart Phones, Lap tops ect)---and he compared this to more complex nervous systems, like in higher animals. He even mentioned that with the nervous system, bio evolution might have peeked, and the only form of advancement now was cooperative life among animals, which is why cooperative living mimics (In communication terms) evolution, because it's an aspect of it.
Anyway, long story, but the interesting thing was that through it all, the cells of had to adapt. If we view humans as components of "society organisms", with how fast information gets exchanged, I wonder if that study about Autism being a form of adaptation isn't onto something. Maybe our primitive social cues are just dying out, and people are switching over to a more effifient method of communicating information.
TLDR--We're going to be like these guys eventually. No emotions, or defining features, just junctions for information.
Of course, we could always go the Borg route too, that would be cool.
