The Selfish Gene (Oxford Landmark Science)

by Richard Dawkins

[gmcgregor]

Richard Dawkins' debut book, The Selfish Gene, was one of those books that I'd been meaning to read and never really wanting to. But I finally made myself, and it turned out I was glad that I picked it up! It examines a fundamental question about human nature: are people naturally generous, or are we naturally selfish? And to what extent is altruism (or the lack thereof) transmitted through our genes? To answer these questions, Dawkins examines how complex organisms, up to and including humans, evolved, to what extent behavior patterns are genetically transmitted, how deeply we might be motivated to help others depending on closely we're related to/share genes with them, and even gets into game theory.

The fundamental premise of the book is that genes "want" (to the extent that inanimate bodily particles want anything) to be passed on. Which one might think would automatically mean that genes that encode for behavior patterns that are selfish/centered on one's own survival at the expense of others would win out, but it's not as easy as that. One's genes also have an investment in being helpful (to a certain extent) to those who have a high likelihood of sharing them: parents, children, siblings, and to a lesser extent aunts/uncles, grandparents/grandkids, etc. And then there's the reality that we'll all need help, of some form or another, at some point, so there's a benefit to providing it to others in the hopes that it'll be returned when needed. So while it's not true altruism, there is some level of unselfishness that's been built in to most of our genetic codes as well.

I read one of Dawkins' later works a few years ago (The God Delusion), and did not like it at all. I found his authorial voice pedantic and grating. But The Selfish Gene is a science classic, so I made myself read it even though I thought I might not like it...and I didn't notice the same kind of condescending attitude. In fact, I thought it struck a good middle ground between dumbing down the concepts to the point where it's so basic there's no room for nuance, and be so technical it ends up talking over the heads of a non-science audience. Instead, it boiled concepts down to a level I felt comfortable with (I have an advanced degree, but I never took science beyond basic high school biology and chemistry because it just never much appealed to me) and honestly provided the first explanation of game theory (or at least The Prisoner's Dilemma) that actually took in my brain.

It's still a little bit pedantic, but as someone with a tendency to be a pedant myself I didn't really mind it. Some scientists convey a sense of wonder about the world that a lot of readers really enjoy, though, and if you're looking for something along those lines, this will probably not be for you. If your spiritual beliefs are such that you're going to want some room left for divine intervention as a factor in evolution, this again is unlikely to be a book you'll enjoy. Although he doesn't really touch on religion in this book, Dawkins is a militant atheist and this is strictly scientific. Otherwise, though, there's a lot to get out of this and I'd recommend it to readers interested in genetics and/or altruism!
