Do genes drive culture?
A recently published research paper lends support to the idea that genes and culture influence one another mutually, effectively co-evolving. A link has been proposed between the collectivism-individualism scale of national cultures and a gene that affects the supply of seratonin to the body, the seratonin transporter gene 5-HTTLPR. A media-friendly summary of the research is available. On the background to biocultural anthropology see Bindon (2007). The method used for measuring culture is interesting and fairly well documented (Hofstede 2001; Hofstede and McRae 2004). The individualism-collectivism scale is similar to the ‘group’ dimension in Grid-Group Cultural Theory. This leads to a number of questions: • If 5-HTTLPR can be seen as a ‘group’ gene (i.e. its prevalence is correlated with a communal rather than individual culture), does this mean we should now be looking for a ‘grid’ gene, to confirm or deny the typology of Cultural Theory? To be specific, the individualist-collectiv
