I would recommend most anything by Desmond Morris the Zoologist and Ethologist. Most of his books are about the human species and the insight per page ratio is very high. They are all very readable as well. He does seem to be too confident about some claims he makes, however. It would be nice if he noted that some of the claims that he makes would be controversial in his field.
I particularly enjoyed "Catwatching".
This is the monthly thread for posting media of various types that you've found that you enjoy. I find that exposure to LW ideas makes me less likely to enjoy some entertainment media that is otherwise quite popular, and finding media recommended by LWers is a good way to mitigate this. Post what you're reading, listening to, watching, and your opinion of it. Post recommendations to blogs. Post whatever media you feel like discussing! To see previous recommendations, check out the older threads.
