Economic institutions governing such activities as food sharing among non-k
in, the accumulation and inheritance of wealth, and the division of labor a
nd its rewards are human-constructed environments capable of imparting dist
inctive direction and pace to the process of biological evolution and cultu
ral change. Where differing structures of these institutions take the form
of distinct conventions sustained by (near) mutual adherence, small initial
differences may support divergent evolutionary trajectories even in the ab
sence of conformist behaviors.
