Dan Sperber & Nicolas Claidière (2008) Defining and explaining culture (comments on Richerson and Boyd, Not by genes alone). Biology and Philosophy 23, 283-292.

Abstract: We argue that there is a continuum of cases without any demarcation between more individual and more cultural information, and that therefore “culture” should be viewed as a property that human mental representations and practices exhibit to a varying degree rather than as a type or a subclass of these representations and practices (or of “information”). We discuss the relative role of preservative and constructive processes in transmission. We suggest a revision of Richerson and Boyd’s classification of the forces of cultural evolution. [PDF version]
