Table 1. Divergence time estimations for the four invasive New World Corbicula lineages and the sexually reproducing C. sandai for each of the nodes of the 90–75 RAxML tree (see Fig. 3).
| Tree node | Age (my) | 95% HPD |
|---|---|---|
| Form A | 0.439 | 0.059–1.013 |
| Form B | 0.272 | 0.028–0.664 |
| Form C | 0.370 | 0.039–0.826 |
| Form D | 0.280 | 0.021–0.697 |
| C. sandai | 1.341 | 0.543–2.306 |
| C. japonica | 0.385 | 0.006–1.039 |
| Forms B and C | 0.807 | 0.191–1.627 |
| Forms B, C, and D | 1.139 | 0.291–2.268 |
| Clonal (Forms A, B, C, and D) | 1.492 | 0.401–2.955 |
| Freshwater (C. sandai, Forms A, B, C, and D) | 1.974 | 0.640–3.782 |
Note:
Values include the estimated age of the node in millions of years (my) and the 95% highest posterior density (HPD) interval.
