Handaxes as a measure of the mental capabilities of early hominids

Handaxes are often used to discuss the evolution of mental capabilities in early hominids. There are several reasons handaxes are used for this purpose, but principal among these is the notion that handaxe shape is an arbitrary imposition of form, on varied raw material, that reflects shared mental templates. If this is so, then changes in handaxe shape through time and space may speak directly to evolving mental capabilities. It is argued here, however, that far too little attention has been paid to much simpler levels of explanation that may say much less about mental capabilities. This point is illustrated by re-examining some data sets that have been used by others to show patterns in handaxe shape interpreted as reflecting difference in mental constructs or for elevated mental abilities. It will be argued here that some very basic factors, such as raw materials and reduction intensity, are better able to explain the observed patterns. As a result, the existence of mental templates for preferred handaxe shapes seems unlik ely.
