Is Speciation Accompanied by Rapid Evolution? Insights from Comparing Reproductive and Nonreproductive Transcriptomes in Drosophila

Figure 3

Distribution of ratio of divergence between D. simulans-D. sechellia and D. yakuba-D. erecta. (a) Distribution of ratio of amino acid replacement substitutions in separate clades log2 ( 𝑑 𝑁 1 / 𝑑 𝑁 2 ) to divergence time (according to Kliman et al. [33]) ratio log2 ( 𝑇 1 / 𝑇 2 ), D. simulans-D. sechellia and D. yakuba-D. erecta. (b) Re-evaluation of divergence times between these species. 𝑑 𝑁 ratios are plotted in colors, and 𝑑 𝑆 ratios are plotted in grey. Color codes: red circles accelerated evolution, black: clock-like, green: slow evolution categories, grey: 𝑑 𝑆 ratios.
