Population thinking applied to culture. In the past 50 years, there have been major advances in the study of cultural evolution inspired by ideas and models from evolutionary biology [1–8].Modelling cultural evolution involves, as it would for any complex phenomenon, making simplifying assumptions; many factors have to be idealized away.
