"Darwin's theory of evolution by natural selection was based on the observation that there is variation between individuals within the same species. This fundamental observation is a central concept in evolutionary biology. However, variation is only rarely treated directly. This volume positions the role of variability within this broad framework, bringing variation back to the center of the evolutionary stage. This book is intended for scholars, advanced undergraduate students and graduates in evolutionary biology, biological anthropology, paleontology, morphology, developmental biology, genomics and other related disciplines."--BOOK JACKET
