As with their physical features, so with their behavioral attributes, habilines continued many earlier hominid patterns.
9 million years ago, habilines had at their disposal an array of simple but clearly recognizable choppers, scrappers, burins, and hammerstones, all made in set patterns created by striking a core with a smaller stone to chip off a few sharp-edged flakes.
Habilines could not have been the first creatures to rely on tools.
As reasonably adept toolmakers, however, habilines must have been self-consciously aware of their actions.
Around 2million years ago, habilines occasionally made bone artifacts and were starting to refine their woodworking skills.
