"Uncovering Stone Age Tool Use Through Hands-On Experiments"
Researchers from Tokyo Metropolitan University are using replica stone tools to understand how our ancestors developed and used tools for woodworking during the Early Upper Paleolithic age, about 38,000 to 30,000 years ago. By examining the traces left on stone edges from tasks like cutting down trees and butchering meat, as well as non-use events like dropping and stepping on the tools, the team aims to gain insights into the ancient woodworking techniques.
