A Cautionary Note on an Easy Mistake

Moreover, I also demonstrate that the available data are consistent with the view that at birth the only difference between the hemispheres is that the left hemisphere has more computational power. This implies that the evolution of asymmetries could be the direct result of the evolution of a general physical asymmetry (in size at birth, oxygenization, metabolic rate, perinatal maturation rate). As the quotations from Broca and Lashley show, this view is not novel. My present goal is to show that all the highly specific and intricate facts about linguistic and nonlinguistic asymmetries that have been recently documented can follow from such a relatively simple evolutionary development.
