Reply to the commentaries on "An evolutionary framework for cultural change: selectionism versus communal exchange".

The commentators have brought a wealth of new perspectives to the question of how culture evolves. Each of their diverse disciplines--ranging from psychology to biology to anthropology to economics to engineering--has a valuable contribution to make to our understanding of this complex, multifaceted topic. Though the vast majority of their comments were supportive of my approach, it is natural that a reply such as this focus on points where my views differ from that of the commentators. ... I conclude by saying that I am grateful to the commentators for their diverse perspectives and insights, their overall support for the project, and provocative ideas for where to go from here. Clearly there are many fascinating avenues to explore as we move forward on our quest to understand how culture evolves.
