<p>Estimates from a single Kenyan population sample from each of <i>D. melanogaster</i> and <i>D. simulans</i>, and the divergence between them. (A) estimates of the proportion of non-synonymous substitutions that were adaptive (α). (B) estimates of the number of adaptive non-synonymous substitutions per non-synonymous site (<i>a</i>). P-values are with respect to the control genes, and were determined by bootstrapping. Error bars are 95% bootstrap intervals around the mean, calculated across loci.</p>
