Survival of the Least Fit
“People think about evolution as progress. Evolution’s not progress. Evolution is fitness within an environment. And it actually breeds its own fragility, right? If I’m a finch who happens to inhabit the Galapagos Islands and nobody has a beak that’s seven inches long that can reach into a particular pine cone, then I can grow a beak that is first 1 ½”, then 2”, then 3”, and eventually it’s 7”; it provides a huge advantage. But if that environment changes, a 7” beak becomes an extraordinary disadvantage and I go extinct almost immediately.”—Michael Green, Simplify A
