The Selfish Gene

A young Oxford biologist wrote it in 1976. It carried one idea out of the journals and into the world, and coined a word on the way: meme.

Evolution doesn’t serve the species or the group. It counts copies, and what gets copied is genes. Take the gene’s point of view and the puzzles dissolve: why animals fight, why they help family, why they help strangers. 8 big ideas, each with a picture and a toy to play with.

The book in one breath: Bodies die; genes get copied for millions of years (1). Genes build bodies to carry them (2). “Selfish” means only “good at getting copied” (3). Sometimes that means helping family (4), trading favours (5), or settling into balances no one can break (6). Humans copy ideas too: memes (7). And a gene’s reach doesn’t stop at the skin (8).

Before we start

Five words you will need

Five words carry the whole book. Learn these and the rest follows.

The DNA ladder

Where each idea keeps coming back

13 chapters, drawn as 13 rungs of DNA. Tap an idea to light up where it lives. Tap a chapter to see what it carries.

The idea-to-chapter map is our reading, not Dawkins’s. Titles follow the 1989 and later editions; chapters 12 and 13 arrived in 1989.

The whole book in one picture

How the 8 ideas fit together

At the centre: genes that copy themselves. Around it, one loop: genes build bodies; bodies that spread more copies win. That single rule yields family help, traded favours and stable balances. Then humans start a second copying game, with ideas. Tap any box.

Lock it in

Eight cards to remember

Read the front. Say the idea aloud, in your own words. Tap to check. Repeat tomorrow: spacing is what makes memory stick.

Quick test: which idea is at work?

Read it wisely

Strengths and limits

Why it lasts

One clear lens. One question, “what gets this gene copied?”, explains fighting, family love, cheating and cooperation.
Great thought experiments. Hawks and Doves, Grudgers and Cheats: toy games that make hard maths obvious.
It shaped the field. It carried Hamilton, Trivers and Maynard Smith to millions of readers, and coined meme.

Keep in mind

“Selfish” is a metaphor. Genes have no minds. And Dawkins is explicit: how nature works is not how we should behave.
A lens, not the only lens. Some biologists argue selection also acts strongly on groups or whole organisms (the “levels of selection” debate). Most agree genes are the lasting copies; they disagree on how best to tell the story.
Genes are not destiny. Bodies grow from genes and environment, together. “A gene for X” is shorthand for “a gene that makes X a little more likely”. Genetics since 1976 has proved messier than this picture.
Memes are a loose idea. Good for thinking; “memetics” never became a hard science.

This page explains The Selfish Gene by Richard Dawkins (1976; expanded 1989; later anniversary editions) for learning. A summary in our own words, not a copy of the book. Quotes are short lines widely attributed to Dawkins (or, where noted, to others he quotes); check your edition. The simulations are teaching models: they show the logic of the ideas, not real biological data.
