The existence of linked regularities in size among brain componentsacross species is, by itself, not a strong argument against theimportance of behavioral selection in brain evolution. A carefulconsideration of hominid brain evolution suggests that braincomponents can change their scaling relationships over time, andthat behavioral selection was likely crucial. The bestneuroanatomical index of a given behavioral ability can only bedetermined empirically, not through comparative analysis of brainanatomy alone.
