Visual Depth Perception in the Animal Kingdom

Show Summary Details


Some insight into how depth-detection systems evolved may be gained by studying mechanisms of depth perception in the animal kingdom, from insects to mammals. Most of our knowledge about visual depth perception has come from cats and primates. But in the animal kingdom there is a great variety of mechanisms of depth perception and some remarkable examples of parallel evolution of these mechanisms. This chapter reviews some of the highly specialized visual mechanisms that have evolved in response to the demands of particular ecological niches. It ends with a discussion of how frontal vision and stereoscopic vision may have evolved.

Keywords: evolution of depth perception; evolution of stereopsis
