These are as follows: (1) bifacial-tool, or hand-ax, traditions (Abbevillian and Acheulean); and (2) flake-tool traditions (Clactonian and Levalloisian).
In all, 18 different types of implements have been discovered for the Acheulean industry—including chisels, awls, anvils, scrapers, hammer-stones, and round balls.
Stone has been used to make a wide variety of different tools throughout history, including arrowheads, spearheads, and querns. Stone tools may be made of either ground stone or chipped stone, and a person who creates tools out of the latter is known as a flintknapper.
Who first discovered fire?
Homo erectus Claims for the earliest definitive evidence of control of fire by a member of Homo range from 1.7 to 2.0 million years ago (Mya). Evidence for the microscopic traces of wood ash as controlled use of fire by Homo erectus, beginning some 1,000,000 years ago, has wide scholarly support.
How did stone Age make fire?
If early humans controlled it, how did they start a fire? We do not have firm answers, but they may have used pieces of flint stones banged together to created sparks. They may have rubbed two sticks together generating enough heat to start a blaze. Fire provided warmth and light and kept wild animals away at night.
