Copy, Change, Compete

Every meme you’ve ever seen went through the same four-step loop.

Transmission. An idea has to leave one head and reach another: speech, writing, a song, a screenshot. No transmission, no meme.

Imitation. The receiver copies it: retells the joke, hums the tune, reuses the format. Copying is what makes it a meme and not just a message.

Variation. Copies are never perfect. Someone changes a word, swaps the picture, adds a punchline. Most changes go nowhere. A few make the meme better at spreading.

Selection. Attention is limited. People can’t share everything, so they share what grabs them. The versions that get chosen multiply; the rest fade.

Then the loop runs again, and again. Run it enough times and a meme can drift far from where it started. That’s cultural evolution: no one in charge, no plan, just copying with small changes and a lot of competition. Online, you can watch it happen in a week.

Copy, change, compete, repeat. That’s evolution without DNA.

Try it

The five-person whisper chain. Write a one-sentence story. Whisper it to a friend, who whispers it to the next, five people deep. Write down what the last person heard. What changed (variation)? What survived intact (fidelity)? Which version would you repost (selection)?

Quick check

What are the four steps?
Transmission, imitation, variation, selection.
Why does variation matter?
It creates new versions, and some spread better than the original.
What does selection “select” for?
Whatever wins attention and gets shared.
