The static and the phylogenetically controlled evolutionary allometric slopes between molar width and length and their contrast. 95% confidence intervals for the parameters, coefficient of determination (R², i.e. the squared correlation coefficient of the matrices) and p-values are estimated from the MCMC resampling for variances and covariances estimates.

parameters	estimate	95% CI	R2	MCMC p-value
static allometric slope (bs)a	0.57	0.47 to 0.67	0.20	<0.001
evolutionary allometric slope (be)	0.49	−0.11 to 1.16	0.38	0.061
contrast evolutionary versus static slope (be – bs)	−0.08	−0.83 to 0.49	—	0.401

^aThe equivalent REML estimates of the static allometric slope of the pooled within-population regression is 0.58 ± s.e. 0.05.
