Table 1. Predictions for life history timing and adult brain and body mass with a me-vs-nature setting and the benchmark parameter values.

Switching times and adult values resulting with competence as a power or exponential function (PC and EC) for the results in Fig 3. *Observed values in human females: age at maturity [100], adulthood [101], brain growth onset and arrest [96], adult body mass [96], and adult brain mass [96]. †Encephalization quotient, calculated as $\text{EQ}=x_{\mathrm{b}}^{*}\left(t_{\mathrm{a}}\right)/[11.22\times {10}^{-3}{x}_{\text{B}}^{*}{\left(t_{\mathrm{a}}\right)}^{0.76}]$ (mass in kg) [102].
