Some scientists remain wary of evolutionary theory because of its supposed
genetic determinism and insensitivity to the inequalities often associated
with gender, race and class. Our aim is to show that such fears are outdate
d and to foster a role for evolutionary theory in public health. We use com
plex adaptive systems theory and the concept of a tradeoff between current
and future reproduction to argue that when the future is objectively risky
and uncertain the optimal reproductive strategy will often be to reproduce
at a young age and/or high rate. Because reproducing early and/or often can
lead to ill health and shortened lives, and because inequality is a major
source of environmental risk and uncertainty, we argue that any attempt to
use evolutionary theory to understand human reproduction, health or wellbei
ng must include considerations of inequality and social capital.
