Peter MacNeilage' "Origins of the Left & Right Brain" Published in Scientific American
Posted: July 1, 2009
Peter MacNeilage, professor of psychology in the areas of Cognition and Individual Differences and Evolutionary Psychology, is the author of an article published in the July 2009 issue of Scientific American. "Origins of the Left & Right Brain" proposes that, "The division of labor by the two cerebral hemispheres--once thought to be uniquely human--predates us by half a billion years. Speech, right-handedness, facial recognition and the processing of spatial relations can be traced to brain asymmetries in early vertebrates." Dr. MacNeilage is the author of The Origin of Speech, which was published last year. His main research interest is in the evolution of complex action systems, which has led him to develop theories of the evolution of handedness and the evolution of speech.
