Results from comparisons of H. sapiens male and female ontogenetic trajectories.

P values (*P��0.01; **P��0.001) from bootstrap tests comparing the major axis slope (above diagonal) and y intercepts (below diagonal) for male and female ontogenetic trajectories. Bold P values indicate level of significance after applying sequential Bonferroni correction. R values, major axis slope and y intercepts for trait relationships are given in Table S3. For trait definitions see below. In the mandible, the intercept and slope comparisons indicate that nearly all of the trait relationships comply with a model of ontogenetic scaling with the exception of the relationship between the distance between condyle and coronoid process of the mandible (C-CR) and CHT, CRHT, CBD, GBD, these differ between the sexes.ML, length of mandible (gnathion [gn]�Ccondylion laterale [cdl]); VL, ventral length of mandible (gn�Cgonion ventrale [go]); I-CR (infradentale [id]�Ccoronion [cr]); CHT, posterior height of ramus (go�Ccdl); CRHT, height at coronoid process (go�Ccr); CBD, bi-condylar breadth (cdl�Ccdl), GBD, bi-gonial breadth (go�Cgo); CRBD, bi-coronoidal breadth (cr�Ccr); SHT, symphysis height (gn�Cid); C-CR, distance between condyle and coronoid process (cdl�Ccr).
