They sure do have a lot of studies about Autism and Aspergers these days. I have to say I am paying attention to see if they end up concluding it is fundamentally an expression of human variation such as hair color or if it is some kind defect such as being born with no left arm and maybe having a more adept right arm as a result. I am certainly pulling for the former "explaination". I like to think that it is a trait built into the human genome that guarantees that a certain percentage of people born will have in order to perform certain tasks that society needs. I liken this to a colony of ants where some ants were born to be workers and others born to be soldiers. So, I like hearing about genetic factors, but cringe at possible environmental causes. But reguardless of its source, I do know God gave us all different "talents" and "gifts" for a reason.
