Cetaceans have complex brains for complex cognition

PLoS Biol. 2007 May;5(5):e139. doi: 10.1371/journal.pbio.0050139.

Abstract

A group of eminent cetacean researchers respond to headlines charging that dolphins might be "flippin' idiots". They examine behavioural, anatomical and evolutionary data to conclude that the large brain of cetaceans evolved to support complex cognitive abilities.
