>>61628 That's mostly true. Neurochemistry also impacts how we respond to internal stimuli as well, however (e.g., cognition, physiology, etc.) But yes, regardless of the model (e.g., Watson, Schachter and Singer, Zajonc), emotions involve both the physiological component as well as some form of subjective interpretation and cognition. >>61629 Natural selection involves anything in the critter's environment. A species that is prone to being selected out of the environment due to predation, for example, is still being naturally selected. The same is true in the other direction -- selection can work in a creature's favor if it's particularly cute and prone to being protected by other critters as well.
