The argument advanced here represents a preliminary attempt to combine the theory of gene-culture coevolution proposed byLumsden, and Wilson, (1981, 1985), the extension to selfish-gene theory made byDawkins, (1982), and the work with my colleagues, Robin Russell and Pamela Wells on genetic similarity theory (e.g., Rushton, , Russell, , and Wells, , 1984, 1985). Although references exist in the text to these works, I am pleased to more formally acknowledge my indebtedness in this note. Any errors or misapplications, of course, are entirely my own.Google Scholar
