Selection: The Mechanism of Evolution

Graham Bell


Adaptation is caused by selection continually winnowing the genetic variation created by mutation. In the last ten years, our knowledge of how selection operates on populations in the field and in the laboratory has increased enormously, and this book aims to provide an up-to-date account of selection as the principal agent of evolution. In the classical Fisherian model, weak selection acting on many genes of small effect over long periods of time is responsible for driving slow and gradual change. It is now clear that adaptation in laboratory populations often involves strong selection acting ... More
