I heard Limbaugh talking about this. He's making a mountain out of a molehill in my opinion and mustn't have a lot to talk about otherwise. The idea that human behaviour has a genetic component to it does not mean that every detail of behaviour is hard-wired into our genes, as Rush would have us believe the scientists are saying. Some aspects of behaviour is instinctive, some is learned. In creatures like insects and in some aspects of bird behaviour, everything is preprogrammed stereotyped behaviour. In humans, a lot more is obviously learned. All this guy is saying is that the urge to find some spiritual fulfillment may have a genetic component to it. The details depend on the cultural setting, the same as language. Rush is justing looking for a stick to beat scientists with, in my opinion. Flame away.
Science isn't his strong suit, and sometimes reading comprehension isn't as well.
