The Blomberg’s K based test of phylogenetic signal analysis shows high
value (K>1) in morphological trait in SVL, SL and INS
indicating relatively more phylogenetic signal. The comparisons of model
fit based on the AICc and AICc weights (ω) indicate the BM model is
preferred in SVL, SL and INS, where trait changes between clades can be
predicted upon their relatedness. Following a divergence event along
phylogeny, that is less labile than expected under a BM model of
evolution clades branches may be subject to phylogeny, such as promoting
the evolution of different morphological traits under climatic
tolerances, which may be accumulated independently from ancestral ones.
While, the others fitted a WN model, which seems to be unrelated with
shared ancestry but preference of an adaptively phenotypic plasticity
(Table 5), which may be closely related to habitat types adapted by
clades.
