Recently there was a discussion regarding Sex at Dawn. I recently skimmed this book at a friend's house, and realized that the central idea of the book is dependent on a group selection hypothesis. (The idea being that our noble savage bonobo-like hunter-gatherer ancestors evolved a preference for paternal uncertainty as this led to better in group cooperation.) This was never stated in the sequence of posts on the book. Can someone who has read the book confirm/deny the accuracy of my impression that the book's thesis relies on a group selection hypothesis?
No, but the book relies on kin selection to some extent: it's beneficial to share resources with your tribe, but not other tribes.
This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.
