The discovery of 300,000-year-old wooden tools in China has provided insight into the diet and cognitive abilities of early humans in East Asia, suggesting a plant-based diet. The tools were found in oxygen-free clay and may have been used to dig for plants. Reports of the discovery vary, with some outlets focusing on the tools' revelation of early humans' dietary habits, while others mention the development of advanced stone tool technology, although it is unclear how this relates to the wooden tools found.
