There are lots of points to address in your post but I choose not to. Thanks for the Blumenbach post; it was very interesting (but nevertheless does not show Germany to be the origin of the concept of race). Anyhow, I saw this on reddit and found it related, and interesting in general: http://www.scienceblog.com/cms/mit-corrects-inherited-retardation-autism-mice-15065.html http://www.scienceblog.com/cms/mit-corrects-inherited-retard... "The MIT study found that FMRP and mGluR5 are at opposite ends of a kind of molecular seesaw." These kinds of "molecular seesaws" are everywhere in the body. When things are only slightly out of balance you _may_ get drastic effects. Emphasis on may, because at this point nobody knows exactly what and how much of it is required to achieve what effect. But there you have it -- once it is identified, it is manipulable. The more important point is, many symptoms are graded in severity, and as this study shows, autism could be found to be less disconnected from normal than you may think.
