A postmortem study of the corpus callosum in the common minke whale ( Balaenoptera acutorostrata )
Abstract Cetaceans diverged from terrestrial mammals approximately 53 mya and have evolved independently since then. During this time period, they have developed a complex nervous system with many adaptations to the marine environment. This study used stereological methods to estimate the total numb...

Abstract Cetaceans diverged from terrestrial mammals approximately 53 mya and have evolved independently since then.
