Early humans made tools by shaping rocks and stones into desired shapes using other rocks as hammers. They also used bones and antlers as tools by sharpening them to cut and scrape. This process of making tools is known as knapping and allowed early humans to better control their environment and improve their survival.
The wedge is one of the six simple machines and may have been the first or second developed (along with the Lever. When early humans made scrapers, axes and knives from stone, they were making a wedge.
Archaeologists study early humans by digging up and studying the traces of early settlements
