Genes do more than carry information; they respond to experience.[1] Susan Mineka illustrated this concept exceedingly well with her idea of prepared learning in monkeys,[32] where she found the predisposition of genes largely affected the acquisition of fear responses to certain stimuli. Lab-reared monkeys, through vicarious experience, were easily able to acquire a fear response to a snake, but not a flower. Nature provides the instinct, and elements of nurture depend on whether the instinct is expressed.
