Brain size and intelligence

Large brain or small brain…what would you prefer?

Human intelligence does not appear to be linked to our brain size. Various measurements have failed to show a correlation between mental capacity and brain size/weight in higher animals. In general, relative weight of brain (as percentage of body weight) decreases with increase in body size (top figure). However, absolute brain weight increases in proportion to body size (bottom figure).
