The life history of learning: Demographic structure changes cultural outcomes
Fig 2
The spread of a cultural trait changes based on learning life histories.
Frequency of T in a population where the trait arises at a frequency of 0.001 in all age classes Parameters were: b = 5, s1 = 0.5, s2 = s3 = s4 = 0.6, s5 = 0.2, wf = 1, ws = 0.05. 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. Panels A, B, C, and D show results of the model for learning strategies corresponding to the strategies from Fig 1: A. Late horizontal or oblique learning, B. hunter-gatherer population, C. agriculturalist population, D. early horizontal or oblique learning.
