Why "Natural Selection" Became Darwin's Fittest Metaphor - Facts So Romantic

Some metaphors end up forgotten by all but the most dedicated historians, while others lead long, productive lives. It's only a select few, though, that become so entwined with how we understand the world that we barely even recognize them as metaphors, seeing them instead as something real. Of course, why some fizzle and others flourish can be tricky to account for, but their career in science provides some clues. Metaphors, as we all by now know, aren't just ornamental linguistic flourishes--they're basic building blocks of everyday reasoning. And they're at their most potent when they recast a difficult-to-understand phenomenon as something familiar: The brain becomes a computer; the atom, a tiny solar system; space-time, a fabric. Metaphors that tap into something familiar are the ones that generally gain traction.
