“The selfish gene” by Richard Dawkins

The author 🖋

Richard Dawkins is a prominent British evolutionary biologist who studied and lectured at the University of Oxford and a bestselling author with over a million copies sold.

He’s also know for popularizing the term "meme" to describe cultural ideas that spread like genes.

Key takeaways 🎓

1. Genes are in charge

Living organisms are essentially just "survival machines" for genes.

Dawkins argues that the primary unit of natural selection is not the individual organism, but the gene.

Everything we humans do - from eating to having children - is so that our genes can make more copies of themselves and continue into the future.

2. Altruism is selfish

Cooperation, especially among relatives, can be explained by genes working to ensure their own survival in other bodies.

When animals help their each other - even if it looks like they’re being nice - in reality they’re just trying to preserve copies of their own genes that exist in others.

This concept provides a genetic basis for understanding cooperative behaviors in nature and challenges traditional views of altruism as purely selfless acts.

3. Ideas spread exactly like genes

Dawkins introduced the concept of “memes” as a way to describe how cultural ideas, behaviors and traditions spread in a manner similar to genes.

Based on him, units of cultural information also replicate by being transmitted from one person to another, competing for attention and survival in our minds.

This idea has since developed into the field of memetics.

Closing thoughts 🧠

The book popularized the gene-centered view of evolution, sparked debates across various disciplines and continues to influence fields beyond biology.

Dawkins argues that genes always act selfishly in ways that ensure their own survival and replication (even when this may come at the expense of the individual organism).
