Did Darwin Write the Origin Backwards?

by Elliott Sober
Amherst (NY): Prometheus Books, 2011. 225 pages.

Elliott Sober’s Did Darwin Write the Origin>cite> Backwards? contains five chapters, reviewer Doren Recker explains: “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.”
