Abstract
In this essay I will explore the important connection between conformism as an adaptive psychological strategy, and the emergence of the phenomenon of ethnicity. My argument will be that it makes sense that nature made us conformists. And once humans acquired this adaptive strategy, I will argue further, the development of ethnic organization was inevitable. Understanding the adaptive origins of conformism, as we shall see, is perhaps the most useful way to shed light on what ethnicity is—at least when examined from the functional point of view, which is to say from the point of view of the adaptive problems that ethnicity solves. I shall begin with a few words about our final destination.
