Fig. 1: The curvilinear relationship of the BBM relationship across mammals.
From: Co-evolutionary dynamics of mammalian brain and body size

a, Brain and body size data used in this study coloured by mammalian taxonomic group. b, Slope coefficient (and percentiles of posterior distributions plotted as transparent lines) for each taxonomic group from a, plotted against body mass (percentiles of body mass range plotted as transparent lines) for each group. c, The median model prediction for our curvilinear BBM relationship across mammals from the variable rates regression model (black) with the variable-slope model predictions for comparison. d, Actual brain mass against predicted brain mass from the curvilinear model, highlighting the accuracy of the fit to the data. In all panels, points and lines are coloured according to orders as shown by representative silhouettes (see legend, not to scale).
