The Cultural Brain Hypothesis: How culture drives brain expansion, sociality, and life history

Social learning over generations starting with s = 1.0.
Social learning is maladaptive i the absence of adaptive knowledge. Asocial learners quickly invade. It is only when asocial learners have generated sufficient adaptive knowledge that social learners again have an advantage. Since we know that at least two regimes reliably emerge, mean social learning in these plots represents the relative number of conditions in which social and asocial learners emerge rather than a value of social learning characteristic of the world.
