The extent to which that revulsion is instinctual is a question I'm unfamiliar with, but has to be some degree of cultural. While instincts obviously must have a hereditary component, I'm unsure of how much of those are actually instinct. Otherwise, this is all evopsych, which is conjectural and of dubious validity. So yes, I do want citations on studies of infant's reactions to these animals.
