Cultural species and their ecosystems

The target article was written for a workshop that I organized with Lin Ostrom titled “Rules as Genotypes in Cultural Evolution”. In my commentary, I describe the background for the workshop and target article in addition to commenting on the article itself. A compelling case can be made for functionally organized human groups as like species that adapt to their local environments. A cultural inheritance mechanism is required for this to happen, which functions analogously to genetic inheritance, although the mechanistic details need not be analogous. Indeed, a diversity of cultural inheritance mechanisms are possible that need not be mechanistically analogous to each other. In addition, most modern human populations consist of a diversity of functionally organized groups, or cultural ecosystems. The distinction between “species” and “ecosystem” is important because the concept of an inheritance system applies primarily to the former. Finally, positive cultural evolution in modern large-scale society must be engineered and an explicitly evolutionary perspective will add value to the enterprise.
