Table 2. Results of tests for phylogenetic signal in developmental mode and cortical thickness of humeri and femora of adults and neonates, using Blomberg’s K test-statistic.
| Parameter tested | K Statistic | P-value |
|---|---|---|
| Adults, Humerus (ACT) | 0.804 | 0.591 |
| Adults, Femur (ACT) | 1.060 | 0.197 |
| Neonates, Humerus (ACT) | 0.804 | 0.613 |
| Neonate, Femur (ACT) | 1.061 | 0.207 |
| Adults, Humerus (RCT) | 0.860 | 0.433 |
| Adults, Femur (RCT) | 1.101 | 0.089 |
| Neonates, Humerus (RCT) | 0.813 | 0.689 |
| Neonate, Femur (RCT) | 1.235 | 0.043* |
| Developmental Mode | 1.317 | 0.005* |
| log10(NHACT) ~ log10(NFACT) + log10(NBM) | 1.286 | 0.028* |
Note:
ACT, absolute cortical thickness; RCT, relative cortical thickness; measured as the ratio of average cortical thickness to average total cross-sectional diameter. The final row shows results of a test for phylogenetic signal in the residuals from a PGLS analysis of the model described (NHACT, neonate humerus ACT; NFACT, neonate femur ACT; NBM, neonate body mass). Significant P-values are indicated by asterisks.
