An evolutionary lens can inform the study of cultural forms in a myriad of ways. These can be construed as adaptations, as exaptations (evolutionary byproducts), as gene–culture interactions, as memes, or as fossils of the human mind. Products of popular culture (e.g., song lyrics, movie themes, romance novels) are to evolutionary cultural theorists what fossils and skeletal remains represent to paleontologists. Although human minds do not fossilize or skeletonize (the cranium does), the cultural products created by human minds do. By identifying universally recurring themes for a given cultural form (song lyrics and collective wisdoms in the current article), spanning a wide range of cultures and time periods, one is able to test key tenets of evolutionary psychology. In addition to using evolutionary psychology to understand the contents of popular culture, the discipline can itself be studied as a contributor to popular culture. Beginning with the sociobiology debates in the 1970s, evolutionary informed analyses of human behavior have engendered great fascination and animus among the public at large. Following a brief summary of studies that have explored the diffusion of the evolutionary behavioral sciences within specific communities (e.g., the British media), I offer a case analysis of the penetration of evolutionary psychology within the blogosphere, specifically the blog community hosted by Psychology Today.
