Two billion-odd years ago, one of the most important meals in history took place. One bacterium swallowed another one. But instead of being digested, the swallowee survived. And it kept doing what it had always done: using oxygen to rip apart food molecules, and then using the energy released to make ATP. So the bacteria that did the swallowing suddenly had this little lump inside it that leaked ATP, which the swallower could use to power its own cellular reactions. It was a match made in thermodynamic heaven.
