Figure 7

Evolutionary trajectories of brain and body mass. Evolution of brain (red) and body (blue) mass from the ancestral primate to a) Homo (solid line) and Pan (dashed line) and b) Ateles (solid line) and Daubentonia (dashed line) showing parallel increase in brain and body mass; c) Callithrix, and d) Microcebus demonstrating secondary reduction in both brain and body mass: note the reduction in brain mass is lower than the reduction in body mass leading to an increase in relative brain size (see Additional file 1, Table S4).
