That fact is only half true. Humans also have natural fears of the unknown (Which also tends to lead to fears of darkness) anything unsanitary, pain, and holes... for some reason. And I'm not talking about large holes you can fall down its why plants with indents in them look disgusting. Theres probally tons of others but these are the ones I know for sure are natural.
