The price of altruism
The book alternates between the story of George Price, and the work of others on how altruism fits in with evolution. We hear of Price's early life, and how he seemed to be heading towards a successful career in mid-20th Century America - he worked on the Manhattan project for a while, he got a job at IBM and wrote controversial popular science articles. But instead he was becoming a drifter, and he moved to London without a job. Here he had a stroke of luck - his genius was recognised and he got a grant to work on the mathematics of evolution. This is when he came up with the Price Equation, which helped to resolve the paradox of altruism. Unfortunately he drifted away from his new career, and committed suicide aged just 52.
I felt that altruism is rather a broad subject, and the alternation between Prices biography and the other work - often at a different time period - sometimes made the book difficult to read. It might have been better to focus on group selection and how its problems were resolved by Price's work. That said the book contains plenty of interesting material if you don't mind the flipping between different stories.
