more recent evidence dating to approximately 164,000 years ago found that early humans living in south africa in the middle stone age used fire as an engineering tool to alter the mechanical properties of the materials they used to make tools and improve their lives. researchers found evidence that suggests early humans applied a method of heat treatment to a fine-grained, local rock called silcrete. once treated, the heated rocks were modified and tempered into crescent shaped blades or arrowheads. the evidence suggests that early humans probably used the modified tools for hunting or cutting meat from killed animals. researchers postulate that this may have been the first time that the bow and arrow was used for hunting, an advancement that had a significant impact on how early humans may have lived, hunted, and existed as community groups.

these distinctions are often blurred. for instance, a bone removed from an animal carcass is a biofact, but a bone carved into a useful implement is an artifact. similarly there can be debate over early stone objects that could be either crude artifacts or naturally occurring and happen to resemble early objects made by early humans or "homo sapiens". it can be difficult to distinguish the differences between actual man-made lithic artifacts and geofacts – naturally occurring lithics that resemble man-made tools. it is possible to authenticate artifacts by examining the general characteristics attributed to man-made tools and local characteristics of the site.
