“If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis (or the atomic fact, or whatever you wish to call it) that all things are made of atoms—little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. In that one sentence, you will see, there is an enormous amount of information about the world, if just a little imagination and thinking are applied.”
Fascinated by Feynman’s question, Seed put a similar one to a number of leading thinkers: “Imagine—much as Feynman asked his audience—that in a mission to change everyone’s thinking about the world, you can take only one lesson from your field as a guide. In a single statement, what would it be?” Here are their answers:
“The dazzling diversity of species and biological adaptations over 3.5 billion years of life on Earth owes its existence to “adaptation by natural selection,” which requires just three simple conditions to operate: variation, differential selection (the best performing traits survive and reproduce more effectively than others), and replication of successful traits by subsequent generations, via a double helix of molecules that code for proteins as biological building blocks, or among more complex animals, via imitation or cultural transmission of methods and knowledge.”
