| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Foraging & Botany (foraging_and_botany) | enabling | 62% | expert_inference | Using ostrich eggshells, gourds, skins, or other portable containers depends on identifying usable natural materials and water sources. |
|
| Stone Tool Making (stone_tool_making) | enabling | 60% | expert_inference | Preparing shells, skins, or gourds as portable containers plausibly required cutting, perforating, scraping, or shaping tools, but the source does not make a specific toolkit mandatory. |
