First primate family {Strepsirhines} includes lorises, lemurs, and galagos but not bush babies or tarsiers. They have furless, moist, mucous tissue with cleft down middle between upper lip and nostrils {rhinarium, Strepsirhines}, as in most mammals. They have simple social organization. In Strepsirhines and primitive mammals, main input to amygdala is from olfactory bulb.
Second primate family {Haplorhines} includes tarsiers, monkeys, apes, and humans. It has furry rhinarium {rhinarium, Haplorhines} and movable upper lip for facial expressions. It uses gestures and has complex social organization. In Haplorhines, main input to amygdala is from visual inferotemporal cortex.
