When did “evolutionary psychology” first emerge? Was it with the publication of David Buss’ textbook titled “Evolutionary Psychology” in 1999? Maybe it was the publication of Barkow, Cosmides, and Tooby’s (1992) “The Adapted Mind.” Or was it with the publication of Robert Trivers’ (1985) “Social Evolution?” Maybe Dawkins’ (1976) classic “The Selfish Gene?”
Actually, the basic idea of evolutionary psychology, which is simply the notion that human behavioral patterns are largely the result of natural evolutionary forces (see Geher, 2014), goes back at least as far as Darwin. Consider his book, “The Expression of Emotions in Man and Animals” (Darwin, 1872). In this book, Darwin carefully considered the adaptive function of emotional experiences and expressions from an evolutionary perspective. If that’s not “evolutionary psychology,” what is?
Many of us, who describe ourselves as “evolutionary psychologists,” fully embrace the power of evolution to help us better understand human behavior and our place in the world. Using the powerful lens of evolution to help inform questions of behavior and psychology, the following facts about human nature have been illuminated:
Evolutionary psychology is a tour de force in modern academia, and this area has shown extraordinary potential for shedding light on issues across the scope of the human experience.
This said, for various historical and political reasons, not everyone loves evolutionary psychology (see Geher, 2006). In fact, many academics report that they “believe in evolution” but that they “reject evolutionary psychology” (see Geher & Gambacorta, 2010). From where I stand, the fact that a large proportion of academics reject evolutionary psychology is a significant hurdle to the advancement of knowledge regarding what it means to be human. And, not surprisingly, perhaps, I see this as a shame.
What does it mean to “accept evolution” but to reject “evolutionary psychology?”
As an academic who strongly embraces evolutionary psychology, I often find myself thinking about this idiosyncratic question – what exactly does it mean to accept evolution but to reject evolutionary psychology? Here are some possibilities:
Honestly, I am still trying to figure this out! But, this said, I think it’s important for people to know how powerful evolutionary principles have been in helping elucidate issues that are central to the human experience – from helping us understand education, to physical health, to mental health, to warfare (see Geher, 2014). Want to develop your best possible toolbox for understanding the nature of human behavior? I strongly recommend that you allow Darwin’s ideas into that toolbox.
