I have heard a hypothesis about our continual evolution lately. The prevalence of people on the autism scale is increasing, supposedly because of the increase in information we are required to juggle in our daily lives. People who are able to handle large amounts of information perform better at the tasks we're required to accomplish in most developed countries. The downside is that this sacrifices less important brain functions, which leads in the direction of things like autism.
I have no idea how true this is, but it's something to look into. I'll admit that I'm not personally interested enough to do any more research into the idea.
