Plant use in the Lower and Middle Palaeolithic: Food, medicine and raw materials

There is little surviving evidence for plant use in the Lower and Middle Palaeolithic periods yet the evidence there is, clearly indicates the importance of plants in the diet, as medicines and as raw materials. Here, the current evidence for plants is summarised, and the way this can be used to enrich perceptions of the Lower and Middle Palaeolithic are explored. The evidence for plant food fits well with basic nutritional requirements while the presence of medicinal plants correlates with plant-based self-medication by animals. Many plant-based technologies are likely to have developed early in the Palaeolithic. Though investigating this is challenging due to a lack of evidence, the extensive evidence for use of plant materials as tools by chimpanzees provides a broad backdrop. The ecological knowledge carried by all hominins would have provided a safety net when moving into new regions, while varying levels of neophobia would have enabled adaptation to new environments as hominin populations moved and climates changed. Recent plant use among traditional societies in high latitudes shows that even in locations with reduced biodiversity, plant resources can fulfil essential dietary requirements.
