Document Summary

All vertebrates have musculature for facial expressions, useful for feeding and breathing. In social mammals and especially primates, they can be used for communicative purposes. Two different dimensions for facial muscles perhaps they were coopted later for social purposes. Studies of chimps and humans provide strong evidence that both use of facial expressions in interaction with conspecifics. Pant-hoot: no human analogue (sort of), display of excitement. Similarity in expression: common genetic basis, common musculature, common neural basis (same brain regions), meaning or function (do they express the same emotions, or are they even used for the same purposes) Not all emotions need to be basic or innate. Six possible basic emotions: guilt/shame, admiration, loneliness, schadenfreude, grief, appreciation. Grief seems more like a state, rather long-lived. Paul ekman: most lies succeed because no one goes through the work to figure out how to catch them. People lie to avoid punishment for breaking a rule, either broken by accident or on purpose.
