Stone tools, used by Homo floresiensis, possibly 100,000 years ago.Fire creation and manipulation, used since the Paleolithic, possibly by Homo erectus as early as 1.5 Million years ago.Acheulean stone technology 1.6 million years ago (hand axe).Olduvai stone technology ( Oldowan) 2.5 million years ago (scrapers to butcher dead animals).Many tools were made in prehistory or in the early centuries of recorded history, but archaeological evidence can provide dates of development and use. Based on marks on the bones at archaeological sites, it is now more evident that pre-humans were scavenging off of other predators' carcasses rather than killing their own food. 'Man the hunter' as the catalyst for Hominin change has been questioned. Tools are the most important items that the ancient humans used to climb to the top of the food chain by inventing tools, they were able to accomplish tasks that human bodies could not, such as using a spear or bow to kill prey, since their teeth were not sharp enough to pierce many animals' skins. As well as hunting, other activities required tools such as preparing food, '.nutting, leatherworking, grain harvesting and woodworking.' Included in this group are 'flake stone tools'. Now, more tools are recognized as culturally and historically relevant. Up until recently, weapons found in digs were the only tools of 'early man' that were studied and given importance. One of the earliest distinguishable stone tool forms is the hand axe. Finds of actual tools date back at least 2.6 million years in Ethiopia. This finding pushes back the earliest known use of stone tools among hominins to about 3.4 million years ago. However, a 2010 study suggests the hominin species Australopithecus afarensis ate meat by carving animal carcasses with stone implements. Stone artifacts date back to about 2.5 million years ago. These early tools, however, were likely made of perishable materials such as sticks, or consisted of unmodified stones that cannot be distinguished from other stones as tools. Because tools are used extensively by both humans (Homo sapiens) and wild chimpanzees, it is widely assumed that the first routine use of tools took place prior to the divergence between the two ape species. Other, briefer definitions have been proposed:Īn object carried or maintained for future use.Īnthropologists believe that the use of tools was an important step in the evolution of mankind. The external employment of an unattached or manipulable attached environmental object to alter more efficiently the form, position, or condition of another object, another organism, or the user itself, when the user holds and directly manipulates the tool during or prior to use and is responsible for the proper and effective orientation of the tool. In 1981, Benjamin Beck published a widely used definition of tool use. While a common-sense understanding of the meaning of tool is widespread, several formal definitions have been proposed. The introduction of widespread automation in the 19th and 20th centuries allowed tools to operate with minimal human supervision, further increasing the productivity of human labor.īy extension, concepts that support systematic or investigative thought are often referred to as 'tools' or 'toolkits'.

Harnessing energy sources, such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking an inflection point in the use of tools. The development of metalworking made additional types of tools possible. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools.Įarly human tools, made of such materials as stone, bone, and wood, were used for the preparation of food, hunting, the manufacture of weapons, and the working of materials to produce clothing and useful artifacts and crafts such as pottery, along with the construction of housing, businesses, infrastructure, and transportation.
