All those words and not a peep about his board game Darwinopoly. I played it in college with some members of my anthrpology class as part of a class exercise and let me tell you, asking random classmates if they want to have sex and then rolling for paternity is a thrill that's hard to replicate 20 years later.
This review suggests that the game is now called "Tribes": https://amzn.com/dp/1556343558, but the author is not Jared Diamond. Is this the game you remember?
