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 flying, or that legs, beaks and teeth are adaptively correlated with mode of life.

Paperback. Zustand: New. Print on Demand. Embark on a captivating exploration of the intricate world of animal coloration and its profound role in the eternal struggle for survival. This book delves into the fascinating realm of adaptive coloration, where animals have evolved remarkable strategies to blend seamlessly with their surroundings, advertise their defenses, or deceive both predators and prey. Following in the footsteps of renowned naturalists, the author challenges the skepticism surrounding adaptation, particularly in coloration. Drawing upon a wealth of observations from the field, museums, and laboratories, the book meticulously examines the optical and psychological principles underlying various forms of camouflage, warning signals, and mimicry. Through vivid descriptions and compelling examples, you'll discover the astonishing diversity of nature's artistry, from the subtle countershading of a moth to the bold stripes of a coral snake. The book sheds light on the intricate interplay between genetics, behavior, and the environment, revealing how these factors shape the evolution of animal coloration. Ultimately, this book illuminates the profound significance of adaptive coloration, not only as a testament to the power of natural selection but also as a source of inspiration for human endeavors in camouflage and visual deception.
