Suppose scientists studied a species of plant that grows in shady environments. They measured the size of leaves in two plant populations and found that the size distribution was similar. In addition, they found that plants with larger leaves tended to produce more seeds and that their offspring tended to have large leaves. The scientists also measured the selection differential, \( S \), of leaf size in each population. In population \( \mathrm{A}, S \) equalled \( 1 \mathrm{~cm}^{2} \). In population B, \( S \) equalled \( 2 \mathrm{~cm}^{2} \).
