Supplementary Material

Additional file 1: Comparison between D. melanogaster – D. simulans / D. yakuba – D. erecta.

Additional file 2: Distribution of protiendivergence log2 (P1/P2) to divergencetime ratio log2 (T1/T2), between D. melanogaster D. simulans vs. D. yakuba D. erecta (Supplementary Table 1). The upper limit of the clockwise category is given by the log2 ratio of of divergence times (6.5/8.1) and the lower limit by the log2 ratio 4.3/12.7. Color codes: Red circlesaccelerated evolution, Grey – clocklike, green slow evolution categories.

Additional file 3: Dendrogram of average ω estimates of genes falling under slow, clock-like and accelerated rate categories. Branch lengths represent the proportion of genes with ω values greater than background ω values. P-values for the different tests were corrected using a Bonferroni correction prior to the comparisons. mel: D. melanogaster, sim: D. simulans, sec: D. sechellia, simsecmel: branch leading to the D. melanogaster clade, yak: D. yakuba, ere: D. erecta, yakere, branch leading to the D. yakuba clade, ana: D. ananassae.

Additional file 4: Genes with evidence of positive selection using site models (M8 vs M7) from PAML.

Supplementary data 5: Comparison of gene classification in between the D. simulans - D. Sechellia / D. yakuba – D. erecta and D. simulans – D. melanogaster / D. yakuba – D. erecta analyses.
