Recent studies link human conservative social (and potentially political) behavior to variation in a particular gene (the 5-HTTLPR gene). Interestingly, the relevant variants in this gene are split almost 50/50 in the human population of European descent.

I just read a story about dogs having innate “pessimistic” or “optimistic” responses to novel stimuli, and associated manifestations of anxiety levels.

I wonder if the same or similar gene correlates to such behavior differences in pooches as in humans…
