Table 3 Net rates of body and head shape evolution (Sigma D) for the riverine and lacustrine Sulawesi groups and non-sulawesi group under a brownian model of evolution after phylogenetic transformation. The observed rate ratio gives the ratio of maximum to minimum net evolutionary rate
| Â | Species Means | ||||
|---|---|---|---|---|---|
| Â | Observed rate ratio | p | Sigma D Lacustrine | Sigma D Riverine | Sigma D Non-Sulawesi |
Evolutionary rate of body shape | 11.115 | 0.0001 | 6.481 × 10− 5 | 1.725 × 10− 5 | 5.831 × 10− 6 |
Evolutionary rate of head shape | 3.994 | 0.0003 | 7.729 × 10− 5 | 2.966 × 10− 5 | 1.935 × 10− 5 |
