Many such sites have hominin bones, teeth, or footprints, but unless they also include evidence for tools or tool use, they are omitted here. This list excludes tools and tool use attributed to non-hominin species. See Tool use by non-humans. Since there are far too many hominin tool sites to list on a single page, this page attempts to list ...
Stone tool use – early human (hominid) use of stone tool technology, such as the hand axe, was similar to that of primates, which is found to be limited to the intelligence levels of modern children aged 3 to 5 years. Ancestors of homo sapiens (modern man) used stone tools as follows: Homo habilis ("handy man") – first "homo" species.
The Stone Age is a broad prehistoric period during which stone was widely used in the manufacture of implements with a sharp edge, a point, or a percussion surface. The period lasted roughly 2.5 million years, from the time of early hominids to Homo sapiens in the later Pleistocene era, and largely ended between 6000 and 2000 BCE with the advent of metalworking.
Tool use by animals is a phenomenon in which an animal uses any kind of tool in order to achieve a goal such as acquiring food and water, grooming, defense, communication, recreation or construction. [42] Originally thought to be a skill possessed only by humans, some tool use requires a sophisticated level of cognition. [43]
One of 12 roundels depicting the "Labours of the Months" (1450-1475) A sickle, bagging hook, reaping-hook or grasshook is a single-handed agricultural tool designed with variously curved blades and typically used for harvesting or reaping grain crops, or cutting succulent forage chiefly for feeding livestock.
Stone tools are still one of the most successful technologies used by humans. [28] The invention of the flintlock gun mechanism in the sixteenth century produced a demand for specially shaped gunflints. [31] The gunflint industry survived until the middle of the twentieth century in some places, including in the English town of Brandon. [32]
In the Levant, the Levallois technique was also used by anatomically modern humans during the Middle Stone Age. In North Africa, the Levallois technique was used in the Middle Stone Age, most notably in the Aterian industry to produce very small projectile points. While Levallois cores do display some variability in their platforms, their flake ...
The mano began as a one-handed tool. Once the maize cultivation became more prevalent, the mano became a larger, two-handed tool that more efficiently ground food against an evolved basin or trough metate. [4] Besides food, Manos and metates were used to separate and pulverize clay from earthen debris and stones.
