H. habilis is associated with the Early Stone Age Oldowan stone tool industry. Individuals likely used these tools primarily to butcher and skin animals and crush bones, but also sometimes to saw and scrape wood and cut soft plants.
To create this tool, one would have to use a hammerstone to chip away flakes on the stone to create a side of the stone with a very sharp edge, allowing for the cutting and hacking of an object. This is a unique type of lithic reduction, as only a single side of the stone is retouched to produce the cutting surface of the stone. The side that ...
The Stone Age is contemporaneous with the evolution of the genus Homo, with the possible exception of the early Stone Age, when species prior to Homo may have manufactured tools. [4] According to the age and location of the current evidence, the cradle of the genus is the East African Rift System, especially toward the north in Ethiopia , where ...
Stone tools have been used throughout human history but are most closely associated with prehistoric cultures and in particular those of the Stone Age. Stone tools may be made of either ground stone or knapped stone , the latter fashioned by a craftsman called a flintknapper .
This age pre-dates the current estimates for the age of the genus Homo by half a million years, and would fall into the pre-human period, associated with the direct australopithecine ancestors of genus Homo. It is not clear whether the tools of such a "Lomekwian industry" bear any relation to the Oldowan industry.
The regular use of Prepared core technology is associated with large-brained hominins such as Homo heidelbergensis, Neanderthals and modern humans. Its widespread use is the defining characteristic of the Middle Stone Age period in Africa and the Middle Palaeolithic (~300.000 - 40.000 years ago) in Europe. [5]
The latter two, softer hammers can produce more delicate results. However, a hand axe's technological aspect can reflect more differences. For example, uniface tools have only been worked on one side and partial bifaces retain a high proportion of the natural cortex of the tool stone, often making them easy to confuse with chopping tools.
Stone tools such as flakes and cores used by Homo habilis for cracking bones to extract marrow, known as the Oldowan culture, make up the oldest major category of tools from about 2.5 and 1.6 million years ago. The development of stone tool technology suggests that our ancestors had the ability to hit cores with precision, taking into account ...
