Stone Tools

Stone Age , prehistoric cultural stage, or level of human development, characterized by the creation and use of stone tools. The Stone Age, whose origin coincides with the discovery of the oldest known stone tools, which have been dated to some 3. Paleolithic archaeology is concerned with the origins and development of early human culture between the first appearance of human beings as tool-using mammals which is believed to have occurred sometime before 3. It is included in the time span of the Pleistocene , or Glacial, Epoch—an interval lasting from about 2,, to 11, years ago. Modern evidence suggests that the earliest protohuman forms had diverged from the ancestral primate stock by the beginning of the Pleistocene. In any case, the oldest recognizable tools were found in rock layers of Middle Pliocene Epoch some 3.

One of the features that distinguishes humans and their hominid ancestors from the rest of the animal kingdom is their possession of complex culture, which includes the ability to communicate with spoken language, create art and make tools. The oldest stone tools dated so far are nearly 2. Our ancestors only began to make more refined tools from bone much more recently, probably only within the last , years. Bone tools dated to about 80, years ago have been found in Blombos Cave, on the southern Cape coast of South Africa.

Some scientists have argued that hominids such as Paranthropus robustus were making bone tools in the Cradle of Humankind far longer ago — perhaps more than 1-million years ago — though this is controversial.

The earliest known human-made stone tools date back around human hunter-gatherer societies, lasting from the early Stone Age all the.

A decade ago, when excavators claimed to have found stone tools on the Greek island of Crete dating back at least , years, other archaeologists were stunned—and skeptical.

But since then, at that site and others, researchers have quietly built up a convincing case for Stone Age seafarers—and for the even more remarkable possibility that they were Neandertals, the extinct cousins of modern humans. The finds strongly suggest that the urge to go to sea, and the cognitive and technological means to do so, predates modern humans, says Alan Simmons, an archaeologist at the University of Nevada in Las Vegas who gave an overview of recent finds at a meeting here last week of the Society for American Archaeology.

Scholars long thought that the capability to construct and victual a watercraft and then navigate it to a distant coast arrived only with advent of agriculture and animal domestication. Not until B. But a growing inventory of stone tools and the occasional bone scattered across Eurasia tells a radically different story.

Modern humans braved treacherous waters to reach Australia by 65, years ago. But in both cases, some archaeologists say early seafarers might have embarked by accident, perhaps swept out to sea by tsunamis. In contrast, the recent evidence from the Mediterranean suggests purposeful navigation. Archaeologists had long noted ancient-looking stone tools on several Mediterranean islands including Crete, which has been an island for more than 5 million years, but they were dismissed as oddities.

The Stone Age marks a period of prehistory in which humans used primitive stone tools. Lasting roughly 2. During the Stone Age, humans shared the planet with a number of now-extinct hominin relatives, including Neanderthals and Denisovans. The Stone Age began about 2. Some experts believe the use of stone tools may have developed even earlier in our primate ancestors, since some modern apes, including bonobos, can also use stone tools to get food.

Stone artifacts tell anthropologists a lot about early humans, including how they made things, how they lived and how human behavior evolved over time. Early in the Stone Age, humans lived in small, nomadic groups. During much of this period, the Earth was in an Ice Age —a period of colder global temperatures and glacial expansion. Mastodons, saber-toothed cats, giant ground sloths and other megafauna roamed.

Stone Age humans hunted large mammals, including wooly mammoths, giant bison and deer.

Neandertals, Stone Age people may have voyaged the Mediterranean

Our ancestors were making stone tools even earlier than we thought — some , years older. Sonia Harmand and Jason Lewis — who have found the earliest stone artifacts, dating to 3. The discovery was announced in a paper, 3. Harmand, the lead author, says that the Lomekwi 3 artifacts show that at least one group of ancient hominin started intentionally “knapping” stones — breaking off pieces with quick, hard strikes from another stone — to make sharp tools long before previously thought.

In the s, paleoanthropologists Louis and Mary Leakey unearthed early stone artifacts at Olduvai Gorge in Tanzania and named them the Oldowan tool culture. In the s they found hominin fossils in association with those Oldowan tools that looked more like later humans — and assigned them to a new species, Homo habilis, handy man.

Most early Stone Age tools were made by splintering rocks with either of fossils or stone artefacts – dating back to million years or earlier.

You probably think of new technologies as electronics you can carry in a pocket or wear on a wrist. But some of the most profound technological innovations in human evolution have been made out of stone. Archaeologists had thought that artifacts of this kind had been carried into China by groups migrating from Europe and Africa. But our new discovery, dated to between , and 80, years ago, suggests that they could have been invented locally without input from elsewhere, or come from much earlier cultural transmission or human migration.

Several different species of humans lived on Earth at this time, including modern ones like us. These Chinese artifacts provide one more piece of evidence that changes the way we think about the origin and spread of new stone tool technologies.

Jump to navigation. The term Paleolithic was created at the end of the nineteenth century. The Paleolithic period begins with the first evidence of human technology stone tools more than three million years ago, and ends with the major changes in human societies instigated by the invention of agriculture and animal domestication.

In France, the Neolithic period, which corresponds to the first farming societies, extended from to BCE. During this time, the nomadic way of life was replaced by a sedentary one. Ceramic technology was used make pottery and some stone tools, such as axes, were polished.

Stones tools that are million years old have been unearthed pre-dating the earliest-known humans in the Homo genus.

All rights reserved. To make the newfound stone tools, Middle Paleolithic toolmakers in what is now India expertly flaked multiple thin blades off of a single core of rock, such as the one seen here. Over time, the ancient innovators rejected bulky hand-axes and cleavers, instead opting for sleek flakes of stone meant for cutting and tipping spears. Similar disruptions occurred in Africa among the forebears of modern humans around the same time. But the timing of the Indian transition, spotted in the soil layers of a site called Attirampakkam, is eye-popping.

At , years old—and possibly up to , years old—this tool transition occurred far earlier than it did at other sites in India. That, in turn, could reshape how scientists view the global spread of hominins—humans and their ancient relatives—before modern humans migrated out of Africa some 60, years ago. Some of the recovered stone tips, such as the one seen in the upper right of this image, have narrower bottom portions called tangs. Tangs would have made it easier to attach the points to handles, aiding in spear-making.

Genetic evidence shows that more than 90 percent of humans today descend from a small population of Homo sapiens that left Africa between 60, and , years ago. From there, they rapidly fanned out, reaching the tip of South America by 18, years ago. Some researchers suspected that this wave of Homo sapiens expanded so rapidly because they were armed with advanced stone tools superior to those of the earlier Acheulian culture, which is defined by bulky stone hand-axes and cleavers.

Stone Tool Experts

A rmed with newly discovered Stone Age tools in a village near Chennai, Indian scientists are challenging the popular scientific theory that the Middle Palaeolithic was brought to India by modern humans dispersing from Africa only around , years ago or later. The new evidence suggests that a Middle Palaeolithic culture was present in India around , years ago — roughly the same time that it is known to have developed in Africa and in Europe. Middle Palaeolithic period is considered an important cultural phase associated with modern humans and Neanderthals as well as other archaic hominins.

Stone tools of this period are used by scientists as proxy for studies of early human behaviour. The prehistoric stone tools excavated from Attirampakkam village about 60 kilometers from Chennai push back the period when populations with a Middle Palaeolithic culture may have inhabited India.

A decade ago, when excavators claimed to have found stone tools on the Greek island of Crete dating back at least , years, other.

That honor appears to belong to the ancient species that lived on the shores of Lake Turkana, in Kenya, some 3. First discovered in , these more primitive tools were created some , years before the earliest members of the Homo genus emerged. The earliest known human-made stone tools date back around 2. One of the earliest examples of stone tools found in Ethiopia. The early Stone Age also known as the Lower Paleolithic saw the development of the first stone tools by Homo habilis, one of the earliest members of the human family.

These were basically stone cores with flakes removed from them to create a sharpened edge that could be used for cutting, chopping or scraping. Though they were first discovered at and named for Olduvai Gorge near Lake Victoria, Tanzania, the oldest known Oldowan tools were found in Gona, Ethiopia, and date back to about 2. The next leap forward in tool technology occurred when early humans began striking flakes off longer rock cores to shape them into thinner, less rounded implements, including a new kind of tool called a handaxe.

With two curved, flaked surfaces forming the cutting edge a technique known as bifacial working , these more sophisticated Acheulean tools proved sharper and more effective. Named for St. Acheul on the Somme River in France, where the first tools from this tradition were found in the midth century, Acheulean tools spread from Africa over much of the world with the migration of Homo erectus, a closer relative to modern humans.

They have been found at sites as far afield as southern Africa, northern Europe and the Indian subcontinent. Stone tools found in a neanderthal flint workshop discovered in Poland. Though teardrop-shaped Acheulean handaxes remained the dominant tool technology until around , years ago, at least one significant innovation emerged long before that among early human species such as Homo neanderthalensis, or Neanderthals.

Oldest stone tools pre-date earliest humans

Currently dated to around , years ago, this innovation in toolmaking is associated with the rapid emergence of distinctive regional artifact styles and the effective abandonment of the large handheld hand axes and cleavers that were the hallmark of preceding Acheulean lithic industries Clark This technological change reflects a fundamental shift from the use of handheld tools to the attachment hafting of stone implements to organic handles for use. New scientific dating techniques accurate beyond the 40, year limit of the radiocarbon method have revealed the time span of the Skip to main content Skip to table of contents.

This page has been archived and is no longer updated. Humans occupy a rarified position in the modern world. We are ubiquitous, ecologically dominant, and technologically unrivaled. And yet, three million years ago, our ancestors were a rather unremarkable species of ape — albeit one that walked around on two legs rather than all fours. What happened? How did we become so dominant, so pervasive, so quickly? The secret to our success lies in the intertwined evolutionary histories of our anatomy especially our large brains , our behavioral ecology the remarkably flexible and diverse strategies we use to fuel those brains and overcome many of nature’s other challenges , and — perhaps most importantly — our capacity for cumulative culture our ” ability to accumulate socially learned behavior over many generations The goal of Paleolithic archaeology is to describe and explain the evolution of these interrelated suites of adaptations as well as associated aspects of our biology and culture through studies of the material record of past human behavior.

The origins of stone tool technology in Africa: a historical perspective

The Stone Age record is longer and better documented in eastern Africa. Archaeological and fossil evidence derives particularly from sites within the Rift Valley of the region, often with secure radiometric age estimates. Putative stone tools and cutmarked bones from two Late Pliocene 3. The earliest indisputable technological traces appear in the form of simple flakes and core tools as well as surface-modified bones.

It is not clear what triggered this invention, or whether there was a more rudimentary precursor to it.

Armed with newly discovered Stone Age tools in a village near Chennai, Specific luminescence dating method was used to date tool-bearing.

Stone tools and other artifacts offer evidence about how early humans made things, how they lived, interacted with their surroundings, and evolved over time. Spanning the past 2. These sites often consist of the accumulated debris from making and using stone tools. Because stone tools are less susceptible to destruction than bones, stone artifacts typically offer the best evidence of where and when early humans lived, their geographic dispersal, and their ability to survive in a variety of habitats.

But since multiple hominin species often existed at the same time, it can be difficult to determine which species made the tools at any given site. Most important is that stone tools provide evidence about the technologies, dexterity, particular kinds of mental skills, and innovations that were within the grasp of early human toolmakers. The earliest stone toolmaking developed by at least 2. The Early Stone Age began with the most basic stone implements made by early humans.

These Oldowan toolkits include hammerstones, stone cores, and sharp stone flakes. By about 1. Explore some examples of Early Stone Age tools. By , years ago, the pace of innovation in stone technology began to accelerate. Middle Stone Age toolkits included points, which could be hafted on to shafts to make spears; stone awls, which could have been used to perforate hides; and scrapers that were useful in preparing hide, wood, and other materials.
