Abstract

With the color vision and learning abilities of birds and teleosts now proved, it appears possible that the hitherto puzzling massive variation in color and pattern of certain species, distributed through at least five phyla, is not the result of the mere free play of mutation but represents a protective variation and is the product of what may be called reflexive selection.
