Morphology with them skulls of h. ergaster differ from those of both earlier hominins and modern humans. H. ergaster may have developed more rapidly than modern humans country. Implies makers had shared an idea for design. Hand axes were probably used to butcher large animals. Homo ergaster is classified in genus homo because it shares the same adaptive grade as later members of the genus: data suggests that h. ergaster represented a marked departure from its predecessors.
