Emotion system/evolution/Tooby/Cosmides: Applied to emotional dispositions, Tooby and Cosmides’ argument (Tooby and Cosmides 1990)(1) is that, if differences in emotionality (e.g., low versus high fearfulness) had been subject to selection pressure, they would not have prevailed over evolutionary times but would have converged to an optimal level of emotionality (e.g., medium fearfulness).
VsTooby/VsCosmides: However, as noted by Penke, Denissen and Miller (2007)(2), inter-individual differences in emotionality could have evolved if, as seems plausible, a generally optimal level of fearfulness, irascibility, etc. did not exist in our evolutionary past, but different levels of emotionality were most adaptive in different environments or social niches. >Emotion system/psychological theories.
