ABSTRACT
TOOLS Humans survived in Europe because they could make tools to adapt to their environment and provide food and shelter. The first Europeans made flat pebble choppers by chipping a piece of flint. Over time, they developed more complex tools. The best stone for weapons came from flint or chert, whereas harder stones, such as basalt or sandstone, were used as grindstones. Wood and shell also served as tools or toolmaking materials.
