Surviving the peril of snakes for millions of years required selective pressure favoring primates' specialized visual systems. Compared to that of other mammals, the [[Pulvinar nuclei|pulvinar]] region of the brain &ndash; which helps to visually detect relevant objects &ndash; is disproportionately large and effective in the brains of primates (including [[human]]s).
 
The concept of snakes being a special threat to humans has been confirmed by population -based studies. [[Ophidiophobia]] (phobia of snakes) is one of the most common and intense phobias among the general population. Furthermore, a study reported that around 50% of the people experience dreams about snakes.<ref>{{cite journal|last1=Sagan|first1=Carl|title=Dragons of Eden: Speculations on the Evolution of Human Intelligence|date=26 September 2012|url=https://books.google.com/?id=BQxZsou&pg=PA249&dq=the+dragons+of+eden#v=onepage&q=the%20dragons%20of%20eden&f=false|publisher=Random House Publishing Group|language=en}}</ref>
