Figure 3. — (a–d) Dynamics of fertility and investment in offspring quality through time in four different ecologies. The thick solid line plots mean fertility, the dotted line plots mean investment in survival-and-productivity capital (a), while the thin solid line plots mean investment in social capital (). The left-hand column represents lower inequality in the inputs to status (CV(ɛ) = 0.4), whereas the right-hand column represents higher inequality (CV(ɛ) = 1). The top row represents a lower intensity of status competition (), whereas the bottom row represents a higher intensity (). ρ is held constant at 2.5 across ecologies.
