Why does nature love symmetry? In Asymmetry, Developmental Stability and Evolution, Moller and Swaddle analyse the evolutionary implications of symmetry. They advance and explain their theory that symmetry is related to genetic stability and fitness, and that symmetric individuals appear tohave quantifiable and significant advantages over their asymmetric counterparts. When assessing potential mates or competitors, animals may be able to use symmetry as an honest indication of quality. This interdisciplinary book, with its associated Web-site, will be of interest to students andresearchers in the fields of ecology, evolutionary biology, genetics, and animal behaviour.
