Darwinian Populations and Natural Selection

This short, clearly written book offers a penetrating analysis of the foundations of evolutionary biology. Godfrey-Smith develops a novel conceptual framework for understanding evolution based on the concept of a “Darwinian population,” which refers to any collection of entities capable of evolving by natural selection, and a “Darwinian individual,” which is a member of such a population. He uses this framework to shed light on topics including reproduction, symbiosis, culture, and transitions between levels of organization. The book is a perfect illustration of why science sometimes needs philosophy.
