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

Table 1

Number and (percent) of genes falling under accelerated, clock-like, and slow-rate categories in recently diverged species when compared to older species pairs. (a) Analysis using the published divergence boundaries according to Kliman et al. [33] for D. simulans and D. sechellia, and Tamura et al. [34] for D. melanogaster-D. simulans and D. yakuba-D. erecta. (b) Analysis using the revised divergence time estimates for D. simulans and D. sechellia. (c) Analysis applying the 95% confidence interval boundaries on revised divergence estimates.
