<p style="text-align:justify">Tokyo, Japan – Researchers from Tokyo Metropolitan University crafted replica stone age tools and used them for a range of tasks to see how different activities create traces on the edge. They found that a combination of macroscopic and microscopic traces can tell us how stone edges were used. Their criteria help separate tools used for wood-felling from other activities. Dated stone edges may be used to identify when timber use began for early humans.</p>
Recent stone tool discoveries are prompting a reassessment of the cultural evolution of Homo sapiens around 50,000 to 40,000 years ago.
