Symbolic culture is a realm of patently false signals. From a Darwinian standpoint, it is not easy to explain how strategies of reliance on such signals could have become evolutionarily stable. The archaeological record shows evolving modern humans investing heavily in cosmetics, with a particular emphasis on ochre pigments matching the colour of blood. This chapter discusses the Female Cosmetic Coalitions model of the origins of symbolic culture in the context of hypotheses sometimes considered to be alternative explanations. It is shown that these various hypotheses are not genuine alternatives. Many are not Darwinian, while others either fail to address the question of symbolism or address it but make no reference to details of the archaeological record. It is concluded that the Female Cosmetic Coalitions model offers the most testable and parsimonious way of integrating these different perspectives.

From a Darwinian standpoint, ‘symbolic culture’ is an unsettling notion. Modern science became established in opposition to the idea that culturally accepted fictions can be equated with facts. Yet the concept of symbolic culture requires us to grasp just that paradoxical possibility. Long before the late twentieth century invention of the Internet, evolution allowed humans to flit between two realms: reality on the one hand, virtual reality on the other. Symbolic culture is an environment of objective facts—whose existence depends entirely on collective belief. To use language is to navigate within that imagined world.

The chief value of the study of human origins is that it nails the myth that ‘no revolution can ever change human nature’. It shows, on the contrary, that everything distinctively human about our nature – our ability to speak, to see ourselves as others see us, to aspire to act on moral principle – has come to prevail in our species thanks precisely to the greatest revolution in history, ‘the revolution which worked’.
