Publisher's Synopsis
The astounding breadth of diversity of life on earth intrigues and amazes many people, while the future of world biodiversity is a cause for widespread concern. Within the current context of global interest in biological diversity, this is a review of research into the evolutionary origins of biological diversity and the processes of speciation. Recent studies have discovered considerable genetic and morphological variation both between and within populations of the same species. Yet the relation between this intraspecific variation and the processes of speciation remains poorly understood. When, how, and why do new species arise? The chapters in this book explore the question of how variation arises within species; some emphasize the ecological and behavioural basis of differentiation; others argue for the role of natural selection in generating speciation. Several chapters focus on the important emerging links between sexual selection, sexual conflict, and population differentiation.
