A long and thoughtful book with the takeaway that giving women control over their reproductive choices will solve more world problems than pretty much anything else. Yes, that simple.
Other things I learned:
* War, terrorism and chimpanzee attacks are all basically the same thing and are called "team aggression against an outgroup"
* Believing your own BS is an evolved trait in males, the benefit being that it makes you a more convincing leader, and thus increased success in your team aggression against outgroups
* We probably have more to fear from a nuclear armed Pakistan than a nuclear armed Iran.
* Unfettered access to birth control reduces birth rates (straight from the department of obvious facts)
ETA: I found this interesting article about Iran's initiative to curb their population growth, and really reinforces the author's thesis that voluntary population control. I can't say many good things about Iran, but on their approach to population control, I think they got it right. http://io9.com/how-iran-became-one-of-the-worlds-most-futuristic-count-1570438769/+Jessica
