Reading The Selfish Gene by Richard Dawkins was enlightening and challenging. It's an iconic book, one of the most influential in evolutionary biology, I believe bested only by Charles Darwin himself. I haven’t read On the Origin of Species yet but would love to give it a read at some point. This book offers a look into a gene's role as the central unit of evolution and natural selection.
I don’t know exactly how I first came across this book, but what compelled me to read it was the fact that Richard Dawkins wrote a blurb praising Carl Sagan's The Demon-Haunted World, which is probably my favourite work of science literature that I’ve come across. It's between that and Billions and Billions. Putting the title and author together, I decided it was worth a shot to tackle this monumental work.
Dawkins has a way with words and can transform complex scientific concepts into thought-provoking arguments to support the “selfish gene” theory. Coming into this work, I mistakenly thought it would be about genetics in a broad sense. I had no idea the theory existed and was surprised at how focused it was on this idea. When I think about it now, the title was telling me exactly what to expect, and it feels quite silly to admit that I missed it. Not a flaw in the book—just a display of my naivete on the subject before reading.
I can’t say that this book wasn't tedious. I started reading it in September 2024 and finished it in January 2025, so it took me a very long time to get through it. However, it was well worth the time I spent on it.
Probably the most striking aspect of The Selfish Gene is how Dawkins invites us to view the world through the lens of the gene. This is not the most intuitive perspective, at least for me, as it requires us to step away from the familiar vantage point of organisms and instead imagine the world as brainless genes, following instructions encoded in DNA. Dawkins’ explanation from this view is masterful. He manages to personify genes and present their selfish nature as not an intentional act—which would indicate consciousness—but as a metaphor for the way they propagate and endure from generation to generation. Brilliant and thought-provoking, but challenging to embrace at first.
Once it sinks in, the idea that genes are inherently “selfish” makes total sense. It's not about malice but rather survival, efficiency, and replication. Successful genes behave in ways that promote their continuity. In organisms, this behaviour can appear altruistic or selfish, but it is always selfish from the gene’s perspective.
Dawkins forces us to reconsider what we know about altruism, not as a conscious decision made by the organism but as a property of the genes that ensures their propagation over time. Dawkins’ exploration of reproductive strategies illustrates this concept beautifully. He contrasts the approach of producing as many offspring as possible—a strategy often seen in species with high predation rates or unstable environments—with the approach of investing significant resources into raising fewer offspring, as seen in species with longer lifespans and more stable conditions. Both strategies, while seemingly opposite, reveal the “selfish” nature of genes, as each is tailored to maximize the chances of genetic survival in a given environment. Dawkins shows how genes drive these divergent paths by prioritizing the method that best ensures their propagation over generations, whether through sheer numbers or enhanced survival rates of fewer offspring. These reproductive strategies underscore the adaptability and ingenuity of genes in navigating the challenges of evolution, revealing a kind of "selfishness" that drives evolutionary innovation.
One of Dawkins’ examples involves the idea that the best strategy for a gene might be to have as many offspring with as many partners as possible. From a purely genetic standpoint, this ensures maximum propagation and diversity, enhancing the chances of survival in a variety of environments. However, when viewed from the perspective of a human, this strategy becomes far less practical and more complicated. Factors like cultural norms and emotional bonds add layers of nuance that genes themselves do not account for.
Reading as a human, with our culture, emotions, and complex social structures influencing how we perceive the world, I initially felt that some of Dawkins' ideas lacked nuance. The behaviours and motivations of organisms seemed far too layered to be reduced to genetic self-interest. However, once I fully embraced the perspective of the gene—a mindless molecule with the sole "goal" of survival and replication—these ideas began to make sense, and that's the perspective required when reading this book.
Eventually, Dawkins transitions from the concept of genes to memes, which are units of cultural transmission that replicate and evolve much like genes themselves. This section of the book was tremendously insightful, exploring the common human desire to leave a lasting legacy. While genes are concerned with biological survival and replication, memes offer a parallel in the realm of culture, art, and ideas, allowing individuals to influence the future in novel ways.
There is a significant difference between these two ideas, however. Genes operate blindly, driven by natural selection and the mechanics of nature without awareness. Memes, on the other hand, are shaped by conscious beings, whose sole goal is to deliberately create, discover, or shape society in some way. The way to immortality is through ideas and creativity.
Both genes and memes, however, share a common thread: they replicate by being “successful” in their environment. This comparison deepened my appreciation for Dawkins’ ability to bridge biology and culture, offering a perspective that is as profound as it is thought-provoking.
One of the most intriguing sections was Dawkins' exploration of game theory, which was used as a way to illustrate strategic interactions that drive evolutionary success. Focusing on the Prisoner's Dilemma, he demonstrates how genes and even organisms can decide between different strategies, whether cooperative or competitive and how these outcomes dictate success or failure. These models show how genes use logic that mirrors mathematical models to navigate complex biological challenges.
It is books like these, tedious and challenging as they may be, that really shape the way we think and understand the world around us. This is one thing that makes books such a powerful medium—both fiction and nonfiction have the power to change us. Challenge is good for us—it’s how we learn—and it’s books like these that provide that challenge and shape us. I love this book, and reading in general, for that very reason.
