Evolution, Mind, and Mating Intelligence

How We've Evolved to Pay It Back and Pay It Forward

Selfless love, an expert explains, is a key piece of our evolutionary heritage.

One of the single greatest advances in the evolutionary behavioral sciences in the past several decades can be described as the intellectual bursting of the “selfishness” dam. In 1976, renowned biologist, thinker, and writer Richard Dawkins published The Selfish Gene (Oxford University Press).

The book is, essentially, a highly accessible and powerful summary of Darwin’s ideas on evolution—applied largely (but not fully) to several classes of animal behavior, including the mating habits of the praying mantis, the murderous nature of emperor penguins, and the helpful nature of vampire bats. The Selfish Gene is truly awesome; put it near the top of your list if you have any interest in the world around you.

One intellectual consequence of Dawkins’ provocative title was a focus on the many connotations of the term selfish. He meant the term in a very specific sense—a “selfish gene” is one that codes for qualities of an organism that increase the likelihood of its survival and/or reproductive success. In short, in the future of a species, replicating genes out-exist non-replicating (or poorly replicating) genes.

This is really all he meant.

But those who followed his work elaborated. It made sense to many to perceive of an animal such as a human as a primarily selfish being. After all, the reasoning goes, if genes that exist are selfish, then the products of those genes, including humans, must be too. This fallacious reasoning has driven much of how evolutionary science has progressed since the publication of Dawkins' book, and how evolution (now seen by many as espousing a “red in tooth and claw” take on our kind) has taken on something of a cold angle on what it means to be any kind of organism, including a human.

The bad news is that this misinterpretation (or at least this overly applied extension) of Dawkins' metaphor has not helped the PR of evolutionary science. People from the outside looking in often think, “Evolutionary science? Isn’t that the stuff that says we are animals and we want to kill each other for our own selfish gain?”

Not so pleasant a portrait.

But there is good news resulting from these trends as well, in the form of a landslide of research over the past several decades shedding light on the positives of human nature, from an evolutionary perspective (See Geher, 2014). We can almost think of this time as the dawn of a new field we could call Positive Evolutionary Psychology (yup, PEP!).

Here are just a few directions that evolutionary psychology has followed in painting humans as loving, helpful, and self-sacrificing:

  1. Paying It Back. Giving back to others who have given to you in some important way is hugely significant from the perspective of evolutionary psychology. Trivers’ (1971) landmark work on the topic of reciprocal altruism demonstrated that in relatively long-lived species, such as our own, the tendency for altruism among-non kin may evolve—and it may take the form of people helping others, even strangers. Sometimes this kind of help is “paying it back,” or reciprocating altruistic acts that have come to would-be altruists in a small-social community. Not paying back altruism is socially dangerous—in your social ecosystem, my social ecosystem, and in the social ecosystems of pre-agrarian humans all around the globe. We’ve evolved to pay it back.

  2. Paying It Forward. This is a term that’s been thrown around a lot in recent years, and I love it! It essentially says to give to others—not to reciprocate them for having helped you in the past, but to help them proactively so that they are on good footing moving forward. Maybe they will help you in the future. Maybe they will help others close to you in the future. Maybe they will help the broader community. Your helping them proactively sets the stage for any of these outcomes with the potential to positively influence you, your kin, and your social network. Paying it forward is seen positively in social communities; it helps people develop reputations as altruists or helpers or, more simply, folks whom can be relied upon.

    Without question, such a reputation is adaptive and leads to be positive outcomes (even if indirectly) for the individual who chooses to pay it forward. Think of joining a Big Brother/Big Sister program when you’re in your mid-20s (as I did when I was a graduate student). In such programs, you meet with a young child who just needs a little boost, a little help, an older figure to lean on and talk to. I met regularly with 7-year-old Jacob. He was a great kid, with a dad not so much in the picture, and he benefited from having a young male adult role model. We did what he wanted to do—movies, sledding, mini-golf, swimming, etc. We talked and we stay in touch still. Now a graduate of the University of Vermont and an ace with computers, for him the sky is the limit. My helping him when he was young was paying it forward; and when I see how well he’s done, I’m pretty glad that I put my time in.

  3. Loving Selflessly. An enormous body of work on the evolutionary psychology of love from the past two decades (e.g., Fisher, 1993) has demonstrated how strong our love for another can be. This kind of love, which can be selfless, is also an important part of our evolutionary heritage. Human offspring are altricial (helpless), and acquiring help from multiple adults (such as a monogamous pair of adults) is hugely beneficial to successful development. And when the adults in that pair are fully aligned in their vision of family, which benefits from them being truly in love with one another, parenting will thrive. Love, an inherently selfless act, is a foundational part of the human evolutionary story.

Did Dawkins' juggernaut of a term, Selfish Gene, imply that all features of all organisms are selfish in the colloquial sense? Absolutely not. He simply meant that the qualities of organisms that lead to gene replication are likely (mathematically) to out-exist qualities that do not facilitate such replication. In complex, socially oriented, and long-lived critters like us, it’s very often the case that selfless, other-oriented behaviors—such as paying it back, paying it forward, or loving another in a selfless manner—are exactly the highly evolved things that make us human, and that these are the qualities we share with humans in all corners of the globe.

To some extent, selfish genes in humans have created altruistic apes who focus largely on what they can do to help others and build strong and positive communities.

This sounds like positive evolutionary psychology* to me!
