Early humans in China innovated technology to adapt to climate change one million years ago

To assess the degree to which early stone tool using hominins modified their tool manufacturing behaviours in Eastern Asia, Shixia Yang and colleagues examined three well-known archaeological sites from the Nihewan Basin in North China. Stone tool comparisons between the archaeological sites of Xiaochangliang, Cenjiawan and Donggutuo indicate that technological skills increased at ca. 1.1-1.0 million years ago. The stone tools at Cenjiawan and Donggutuo show increasing levels of control in manufacturing procedures and some degree of planning in the tool-making process to produce the desired end-products.
