People develop phobias of snakes and heights more readily than of motorcycles and weapons, even though the latter are more dangerous today. Which explanation is offered for this?

1. People more often develop phobias of things posing little real danger today, such as animals and heights. 2. One theory holds that the brain is evolutionarily predisposed to associate certain objects and situations with fear. 3. Ancestors linked stimuli such as snakes, spiders, heights and thunder with danger, and the mind adapted to learn those links easily. 4. Experiments back this up: conditioned fears form more readily to snakes and spiders than to flowers and berries. 5. Prepared learning of this kind has been shown in monkeys too, so it is not explained by exposure frequency or cultural training. _Source: OpenStax Psychology (1st ed., CC BY 4.0), Ch 15 "Psychological Disorders", section 15.4 Anxiety Disorders_
