I saw this image in a National Geographic issue a while back.  The article was discussing if fear is primarily a learned or instinctual behavior.  I can't find the article, but I'll keep looking.

EDIT: Here is the article.  The section in question is page 9, titled "Afraid of What?" http://science.nationalgeographic.com/science/health-and-human-body/human-body/mind-brain/#page=9
