Stone Age Tools Research Improves Modern Techniques
Innovative research by the National Physical Laboratory (NPL) and the Univ. of Bradford used laser microscopes to explore how stone tools were used in prehistory, and the process has helped streamline surface measurement techniques for modern manufacturers. The analysis of stone tools is a key factor in understanding early human life including social organization and diet. Archaeologists at the Univ. of Bradford hypothesized that reconstructing past activities was the best way to study what each tool was used for. They proposed to measure the surface structures of replica stone tools before and after they were used in different reconstructions on two natural materials - antler and wood.
