Did Darwin Write the Origin Backwards? Philosophical Essays on Darwin's Theory

Elliott Sober’s most recent book covers a variety of topics in the history, philosophy, and practice of Darwinian evolutionary biology. It contains five chapters, on: (1) the relationship(s) between common ancestry and natural selection in the Origin, (2) group selection, (3) sex ratio theory, (4) naturalism, and (5) a postscript, providing a more detailed, formal account of several issues contained in the first four chapters. The style is fairly informal, with statistical analyses sprinkled here and there, but the main text is understandable without knowledge of formal probability theory. The main audience would be philosophers and evolutionary theorists, though there are some interesting claims concerning more historical issues as well.
