All P-values were significant (P<0.05) except for the following estimates: Among groups-Philippines-Language (0.0; P=0.92); Among groups-Philippines-Negrito and non-Negrito (3.1; P=0.11) and Among populations-Australia (2.2; P=0.13).
Philippine and Reference data set groups are shown in Figure 1.
Philippine groupings are enumerated in Figure 1.
All groups with sample sizes <10 (Figure 1, Supplementary Text) were excluded from the analyses.
