Cooperation and the history of life: is natural selection a team sport?
Cooperation is in our nature, for good and ill, but there is still a nagging doubt that something biological in us compels us to be selfish: our genes.

Not only are humans fundamentally team players, but all of nature has been teaming up since the dawn of life four billion years ago.
