Synopsis

Excerpt from Adaptative Coloration in Animals

Cases in which an unusual resting position is adopted provide beautiful evidence of his contentions. Counter-shading is reversed in fish which swim upside-down and caterpillars which rest inverted. Bark-haunting moths have their markings running parallel with the vertical cracks of the bark, whether they rest with body vertical or horizontal, with wings folded or expanded.

The correlation Of behaviour and markings, indeed, as Poulton long ago pointed out, is one of the strongest supports for theories of adaptive coloration. Even if it were possible for a case-hardened sceptic to dismiss as accidental such isolated facts as the co-existence, In various stingless insects, of a resemblance to bees or wasps on the one hand and on the other of motions simulating stinging, and even of the protrusion of an imitation sting, the enormous array of less spectacular but equally significant correlations provided by Dr. Cott is overwhelming.

Dr. Cott is a true follower of Darwin in driving his conclusions home by sheer weight Of examples. Faced with his long lists of demonstrative cases, the reader is tempted to wonder why adaptive theories of coloration have been singled out for attack by anti-selectionists. Asdr. Cott observes, physiologists and geneticists do not deny that wings exhibit characters which make them suitable as mechanisms for ?ying, or that legs, beaks and teeth are adaptively correlated with mode of life.
