Age estimates for selected clades, obtained with different settings and datasets.
| Setting/Dataset | Holostei and Teleostei | Cichlidae | Cichlinae and Pseudocrenilabrinae |
|---|---|---|---|
| “permissive” gene set | 269.6 (290.0–251.6) | 76.2 (86.6–66.3) | 62.1 (70.1–54.6) |
| “strict” gene set | 269.2 (288.5–251.5) | 76.9 (87.1–66.2) | 62.2 (70.3–54.6) |
| MCMC sampling from prior | 269.6 (290.9–251.5) | 79.7 (94.9–63.9) | 68.0 (81.3–55.1) |
| Without cichlid calibrations | 268.9 (288.7–251.6) | 61.2 (77.8–45.5) | 38.7 (50.8–27.1) |
| Doubled net diversification rate | 264.0 (277.5–251.4) | 73.7 (83.6–64.2) | 60.0 (66.9–53.3) |
| Halved net diversification rate | 277.4 (306.7–251.9) | 79.7 (90.8–69.4) | 63.5 (72.5–55.0) |
| Doubled fossil sampling rate | 263.5 (279.0–251.4) | 73.7 (84.2–64.5) | 59.9 (67.2–52.7) |
| Halved fossil sampling rate | 277.9 (302.5–252.5) | 81.3 (92.3–70.6) | 65.3 (74.1–55.8) |
| (Osteoglossomorpha, Elopomorpha) | 269.4 (289.5–251.5) | 77.3 (88.1–67.9) | 62.2 (70.3–54.9) |
| (Osteoglossomorpha, Clupeocephala) | 269.2 (289.2–251.5) | 76.7 (86.1–66.2) | 62.0 (70.1–54.1) |
Unless specified, the “strict” set of genes was used in all analyses. Mean estimates of crown ages in millions of years are given for the three clades, followed by 95% highest posterior density intervals in parentheses. Specified settings in the last two rows indicate monophyly constraints according to alternative relationships among Osteoglossomorpha, Elopomorpha, and Clupeocephala12, 14. The age estimates obtained with the “permissive” gene set correspond to those shown in Fig. 2.
