The study involved 36 species of mammals and birds. The scientists found that the species with the largest absolute brain volume showed superior cognitive powers. They concluded that big-brained animals, for example, chimpanzees, show more self-control than, say, gerbils. The study also showed that animals with the most varied diets displayed the most self-restraint.
