Fig. 1From: The effect of body size evolution and ecology on encephalization in cave bears and extant relativesScatterplot of log10 brain mass (g) against log10 body mass (g) with a PGLS regression lines (phylogenetic generalized least squares). In black is the PGLS regression line for all data points (p value: 0.0148, slope: 0.43978, intercept: 0.24623, adjusted R2: 0.5378), in red the PGLS regression line without Ursus malayanus and Ursus spelaeus (p value: 0.0016, slope: 0.78069, intercept: −1.50995, adjusted R2: 0.8606). The triangles represent the mean for each species on which PGLS was calculatedBack to article page
