Fig. 6: Ossification sequence and evolutionary rate.
From: Size, microhabitat, and loss of larval feeding drive cranial diversification in frogs
Ossification sequence rank versus evolutionary rate for each cranial region. Evolutionary rates are estimated with error to account for intraspecific variance and departures from Brownian Motion (results estimated without error in Supplementary Fig. 11), with lines derived from a robust regression fit. Two-sided Spearman’s rank correlation of evolutionary rate with ossification sequence rank (from Weisbecker & Mitgutsch43) was significant (mean Spearman’s rho = 0.50, p < 0.01). Colours for cranial regions are as indicated in Fig. 1.
