This makes perfect sense -- it's not that the disease is related to any degree of intelligence -- or vice versa -- it's simply the inescapale genetic consquence of continuously (generation after generation) selecting within a breeding pool that is less open to the influx of new genetic material than average.
The nature of genes is such that when the material of a parent is given into the gamete (the egg or sperm with 50% of the total needed), the genes unravel in
sections -- it's not like a bag of M&Ms - where you could pick out the gene for just this or just that single attribute.
As a result of the comparatively limited influx or genetic through-breeding, you will observe, after many, many generations the presence of common genetic "sections" in such a population. All this means is that they found genetic sections in the the subjects that contained both genes related to intelligence and genes related to certain diseases (which for the VERY SAME REASON) are now generally associated with Jews.
I guess I feel somewhat vindicated by this -- since this is exactly what I was trying to assert in my thread a while ago -- "
Am I a JEW?"
