The life history of learning: Demographic structure changes cultural outcomes
Fig 5
Mean frequency of the cultural trait T in the population when T decreases fertility.
In panel (A), T does not construct a learning niche (ϵ = 0) and in panel (B), it does construct a learning niche (ϵ = 1). Other parameters: wf = −2, vb = 0.6, ω = N = 5. Starting population size was 100 individuals and the simulation ran for 5000 time steps. Starting age structure was uniform with 20% of the population in each age class. Survival parameters as in Fig 3.
