| Malacostraca | 1,326 | 1,320 ± 43 | 291 | 300 ± 115 |
| Maxillopoda | 396 | 360 ± 20 | 67 | 120 ± 37 |
| Amphibia | 129 | 170 ± 15 | 704 | 390 ± 170 |
| Mammalia | 525 | 705 ± 30 | 172 | 85 ± 30 |
These numbers are compared with the predictions of the SEO theory given the parameters γ and ν retrieved from the best fits of the SGD curve. The errors given reflect 1 SD about the mean of the simulated values.
