It's interesting how co-occurrent some genetic/behavioral traits are. I read an article about a study of domesticating foxes. After many generations selecting for propensity to come forward when a human puts out food, the semi-domesticated offspring showed a wide array of physical traits associated with dogs in addition to the behavior that was selected for.

Yet... as computing becomes more popular, I expect this stereotype to become obsolete. It roughly applies to myself and many of my friends. My wife calls me a robot. But hey, somehow most of us managed to find a spouse.
