Why do human beings have binocular vision? Why do they see colour the way they do? Why do optical illusions work? And why are people able to absorb information by reading, a relatively new development from an evolutionary perspective, more readily than by hearing, which has evolved over hundreds of thousands of years? Evolutionary scientist and neurobiologist Mark Changizi answers these questions and more in The Vision Revolution, shattering previous scientific beliefs and giving readers a radically new perspective on the history and function of human vision.
