"Although considerable controversy has existed over the extent to which this fear of snakes is “innate” as opposed to based on learning, current evidence suggests that learning is necessary for the fear to manifest itself, at least for some primate species in which wild-reared but not laboratory-reared monkeys show a fear of snakes (see Mineka & Cook, 1988, for a review). For example, Mineka and Cook demonstrated that laboratory-reared rhesus monkeys who were initially unafraid of snakes rapidly acquired a fear of snakes after watching wild-reared model monkeys exhibit a strong fear of snakes (Cook, Mineka, Wolkenstein, & Laitsch, 1985; Mineka, Davidson, Cook, & Keir, 1984). The naive laboratory reared observers initially reached rapidly for food placed adjacent to a series of stimuli, including a real snake, toy snakes, and neutral objects."
My dog has instinctively done many high level things, peeing on tall things, sexing anything, responding to scolding despite I have never been violent to him, shaking water off with a weird reflex, pooing away from his home etc. It's like those behaviours are already preprogrammed. Being scared of certain classes of animals is no more.complex, I think humans probably have tons of preprogrammed behaviours we later add a narrative to. Perhaps belief in unseen agents is one of them.
