Abstract
A long-standing objective in Acheulean research is defining evolutionary trends in handaxe production over time. This study investigates technological and morphological variability in the Early Acheulean by analysing three geographically and chronologically proximate assemblages (>1.2 million years ago) from Melka Kunture (Upper Awash, Ethiopia). Combined techno-typological and geometric morphometric analyses reveal significant variability in handaxe morphology, shaping strategies and raw material selection. The observed dissimilarity suggests that Acheulean handaxe manufacture did not follow a linear path of standardisation. Rather, it demonstrates considerable flexibility, reflecting hominins’ responses to varying constraints and immediate needs within short timeframes.
