| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Stone Tool Making (stone_tool_making) | historical_predecessor | 72% | primary_source | The Olduvai assemblage documents bone tools shaped by knapping, so earlier percussion-flaking traditions are a close historical predecessor rather than a generic survival context. |
