Natural selection, mutation, and adaptation are well-known and central topics in Darwin's theory of evolution and in the 20th - and 21st -century theories which grew out of it, but many other important topics are used in evolutionary biology that raise interesting philosophical questions. In this book, Elliott Sober  analyses a much larger range of topics, including fitness, altruism, common ancestry, chance, taxonomy, phylogenetic inference, operationalism, reductionism, conventionalism, null hypotheses and default reasoning, instrumentalism versus realism, hypothetico-deductivism, essentialism, falsifiability, the principle of parsimony, the principle of the common cause, causality, determinism versus indeterminism, sensitivity to initial conditions, and the knowability of the past. Sober's clear philosophical analyses of these key concepts, arguments, and methods of inference will be valuable for all readers who want to understand evolutionary biology in both its Darwinian and its contemporary forms.

‘Philosophy of biology has grown into a respectable and autonomous discipline, but also become increasingly specialized and fragmented. Elliott Sober's book is poised to rekindle meta-scientific exploration into the epistemological and ontological dimensions of evolutionary biology, and demonstrates to both philosophers and biologists that evolutionary biology remains a fertile ground teeming with captivating conceptual issues.'

‘Elliott Sober has provided an excellent, lucid tour through all the important concepts and advances in evolutionary theorising from Darwin to the present. His expositions and arguments draw on a wealth of philosophical and biological material, including many of his own original contributions to the field. Philosophers and biologists will find much to ponder, as will non-specialists with an interest in evolutionary theory.'

‘The Philosophy of Evolutionary Theory succeeds in providing readers with a solid foundation in many of the significant topics in evolutionary biology. Like all of Sober’s books, the writing style is clear and succinct. Each chapter aims to summarize one major evolutionary concept and provides insight into debates in the field, along with several suggestions for further study. At first glance, the somewhat modest length of the book would seem to indicate a cursory overview of these complex ideas (e.g., units of selection, fitness, adaptationism, etc.). However, this is a testament to Sober’s ability to explain intricate concepts concisely. Each chapter is a fantastic introduction to these fundamental evolutionary topics and will provide a reader with a sophisticated understanding of often misunderstood ideas. I highly recommend this book to advanced undergraduates, graduate students, and professionals.’
