The relationship between environmental stability, c (where the environment changes every c generations) and the average number of cultural traits in a population (averaged over the final 500 generations of a 1000 generation run for 5 independent runs). Red lines indicate low environmental harshness (h=1), and blue lines indicate high environmental harshness (h=1.1). Dash-dot lines: N=5, solid lines: N=100, dashed lines: N=250, where N is population size. β=0.99. Error bars indicate the standard error of the mean. Compare to Figure 2 in the text where β=0.9.
