And in the case evolution is sentient, autism is here in growing numbers just because evolution likes it the same way it thought we look better with less bodily hair.

I have no idea if you are being serious or not, but evolution doesn't work that way (we look better with less bodily hair) nor are we growing in numbers.
That's kinda like saying you saw a few elephants at the zoo and then go to a wildlife park and see a bunch more. They were always there, you just never saw them before and we ain't even left the continent yet. They are just learning what it is and how it manifests itself, so, they too are just learning to see it.
Not too many years ago, you weren't Autistic unless you were nonverbal and/or banged your head on the wall.
Then they expanded those parameters and finally, recently, they threw Asperger's under the Autism spectrum and that will make the numbers grow. And, Asperger's is still a relatively new diagnoses.
So, no new numbers. Just better quantifiable numbers. There are certain segments that do not agree that Asperger's is Autism. So, if that gets removed, watch the numbers go down. Then, people can claim it's being cured since the numbers are going down.
As for less bodily hair, follicle by follicle, we have as much as the average chimp. Size and thickness are the only variables. And, it can get worn away or lost. But, we are hairy beasts. Just not so noticeable.
