Bigger is smarter: Overall, not relative, brain size predicts intelligence

When it comes to estimating the intelligence of various animal species, it may be as simple measuring overall brain size. In fact, making corrections for a species' body size may be a mistake. The findings were reported by researchers at Grand Valley State University and the Anthropological Institute and Museum at the University of Zürich, Switzerland. The study has now been published online in the journal Brain, Behavior, and Evolution.
