Paperback. Etat : New. Print on Demand. This book challenges Darwin's theory of sexual selection, arguing instead that the origin of secondary sexual characteristics arises from natural selection acting upon associations of individuals, such as pairs and families. These characteristics control natural selection in a way that makes less valuable individuals, such as males and the old, more liable to destruction than the more valuable, such as females and the young. Drawing on a variety of evidence, including conspicuousness in nature, the author presents a new theory of controlled natural selection and value marking, whereby differences in value are associated with differences in structure. This theory helps explain the origin and use of polymorphisms and provides a new perspective on the evolution of sexual dimorphism and other di- and poly-morphisms. This book will be of interest to evolutionary biologists, ornithologists, and anyone interested in the origin and evolution of animal characteristics.
