Cooperation is something that most people take for granted. It’s woven into just about every part of our lives. Our societies have even developed a wide variety of measures to make sure we’re cooperating, such as punishing those that don’t. This level of cooperation isn’t reserved to humans. Cooperation plays a vital role in nearly all forms of life, from our primate cousins to ants and termites, and all the way down to simple microorganisms such as bacteria. There’s even an astounding amount of cooperation going on within our bodies. Amazingly, of the ten trillion or so cells in the human body, over 90% of those are bacterial cells made up of thousands of different species.
