Stone tools were made from a variety of different kinds of stone. For example, flint and chert were shaped (or chipped) for use as cutting tools and weapons, while basalt and sandstone were used for ground stone tools, such as quern-stones. Wood, bone, shell, antler and other materials were widely used, as well. During the most recent part of the period, sediments (like clay) were used to make pottery. A series of metal technology innovations characterize the later Chalcolithic (Copper Age), Bronze Age and Iron Age.
The period encompasses the first widespread use of technology in human evolution and the spread of humanity from the savannas of East Africa to the rest of the world. It ends with the development of agriculture, the domestication of certain animals and the smelting of copper ore to produce metal. It is termed prehistoric, since humanity had not yet started writing -- the traditional start of history (i.e., recorded history).
The term "Stone Age" was used by archaeologists to designate this vast pre-metallurgic period whose stone tools survived far more widely than tools made from other (softer) materials. It is the first age in the three-age system. A division of the Stone Age into an older and younger part was first proposed by Jens Jacob Worsaae in 1859 through his work with Danish kitchen middens that began in 1851. The subdivision into the Palaeolithic, Mesolithic and Neolithic periods that still is in use today, was made by John Lubbock in his now classic 1865 book Pre-historic Times. These three periods are further subdivided. In reality, the succession of phases differs enormously from one region (and culture) to another, indeed, humanity continued to expand into new areas even during the metal ages. Therefore, it is better to speak of a Stone Age, instead of the Stone Age. As a description of people living today, the term stone age is controversial. The Association of Social Anthropologists discourages this use.
The date range of this period is ambiguous, disputed, and variable according to the region in question. While it is possible to speak of a general 'stone age' period for the whole of humanity, some groups never developed metal-smelting technology, so remained in a 'stone age' until they encountered technologically developed cultures. However, in general, it is believed that this period began somewhere around 3 million years ago, starting with the first hominid tool-making in Africa. Most australopithecines probably did not use stone tools (although they seem to be invented by Paranthropus robustus) but the study of their remains still falls within the remit of archaeologists studying the period. Due to the prevalence of stone artefacts, which are frequently the only remains which still exist, lithic analysis is a major, and specialised, form of archaeological investigation for the period. This involves the measurement of the stone tools to determine their typology, function and the technology involved. This frequently involves an analysis of the lithic reduction of the raw materials, examining how the artefacts were actually made. This can also be examined through experimental archaeology, by attempting to create replica tools. This is done by flintknappers who reduce flintstone to a flint tool.
One problem with the term is that it implies that human advancement and time periods in prehistory are only measured by the type of tool material most widely used, rather than, for example, type of social organisation, food sources exploited, or adaption to harsh climates. This is a product of the level of knowledge of the distant past during the nineteenth century when the three age system was developed, a time when finds of artefacts were the main goal of an archaeological excavation. Modern archaeological techniques stress a wider collection of information that has expanded our knowledge of prehistory and rendered neat divisions such as the term 'Stone Age' increasingly obsolete. We now know that the changes in past societies over the millennia were complex and involved multiple factors such as the adoption of agriculture, settlement or religion and that tool use is just one unrepresentative indicator of a society's practices and beliefs.
Another problem connected with the term Stone Age is that it was created to describe the archaeological cultures of charlotteEurope, and that it is inconvenient to use it in relation to regions such as some parts of the Americas and Oceania, where farmers or hunter-gatherers used stone for tools until European colonisation began. Metal-working was a much less important part of people's lives there and it is more useful to use other terms when dividing prehistory in those areas. The same incongruence applies to the Iron Age worldwide, because in the Americas iron (but not copper, silver or gold) was unknown until 1492, in Oceania until the 17th century or the 18th century.
A Stone Age was usually followed by a Bronze Age, during which metalworking technology allowed bronze (copper and tin or other metals) tools to become more common. The transition out of the Stone Age occurred between 6000 BC and 2500 BC for much of humanity living in North Africa, Asia and Europe. In some regions, such as Subsaharan Africa, the Stone Age was followed directly by an Iron Age. It is generally believed that the Middle East and southeastern Asian regions progressed past Stone Age technology around 6000 BC. Europe, and the rest of Asia became post-Stone Age societies by about 4000 BC. The proto-Inca cultures of South America continued at a Stone Age level until around 2000 BC, when gold, copper and silver made their entrance, the rest following later. Australia remained in a Stone Age until the 17th century.
We also now know that the transition from a Stone Age to a Bronze Age was not a neat switch but a long, gradual process involving the working of gold and copper at what are technically Neolithic sites. This "transition" period is known as the Copper age or Chalcolithic. It was a short and more a regional development, because alloying tin with copper began quite soon, except in regions lacking tin. Ötzi the Iceman for instance, a mummy from about 3300 BC carried with him a copper axe and a flint knife. Stone tool manufacture also continued long into the succeeding metal-using ages, possibly even until the Early Middle Ages. In Europe and North America, millstones were in use until deep into the 20th century, and still are in many parts of the world.
The three-age system divides human technological prehistory into three periods:
New ages and subages were added as new archaeological discoveries were made, and different schemes were developed to describe conditions in different places. A more modern periodization of the Stone Age stretches from the Paleolithic to the Neolithic in the following scheme (crossing an epoch boundary on the geologic time scale):
The Paleolithic (or Palaeolithic) (from Greek: παλαιός, palaios, "old"; and λίθος, lithos, "stone" lit. "old age of the stone"; was coined by archaeologist John Lubbock in 1865.) is a prehistoric era distinguished by the development of stone tools. It covers the greatest portion of humanity's time (roughly 99% of human history) on Earth, extending from 2.5 or 2.6 million years ago, with the introduction of stone tools by hominids such as Homo habilis, to the introduction of agriculture and the end of the Pleistocene around 10,000 BC. The Paleolithic era ended with the Mesolithic, or in areas with an early neolithisation, the Epipaleolithic.
During the Paleolithic humans were grouped together in small scale societies such as bands and gained their subsistence from gathering plants and hunting wild animals. The Paleolithic is characterized by the use of knapped stone tools, although at the time, humans also used wood and bone tools. Other organic commodities were adapted for use as tools, including leather and vegetable fibers; however, given their nature, these have not been preserved to any great degree. Humankind gradually evolved from early members of the genus Homo such as Homo habilis who used simple stone tools into fully behaviorally and anatomically modern humans (Homo sapiens sapiens) during the Paleolithic era. During the end of the Paleolithic specifically the Middle and or Upper Paleolithic humans began to produce the earliest works of art and engage in religious and spiritual behavior such as burial and ritual. The climate during the Paleolithic consisted of a set of glacial and interglacial periods in which the climate periodically fluctuated between warm and cool temperatures.

From 35,000 to 10,000 years ago (the end of the last ice age) modern humans spread out further across the Earth during the period known as the Upper Palaeolithic. In the time when Cro-Magnons and Neandethal traits mixed in Europe (35-24.5 ky) a relatively rapid succession of often complex stone artefact technologies took place. During period between 35 and 10 kya evolved: from 35 to 29 kya Châtelperronian, 32-26 Aurignacian, 28-22 Gravettian, 22-17 Solutrean, and 18-10 Magdalenian. The last two after disaperencce of nendertal traits from paleoantropological specimnes.
The Americas were colonised via the Bering land bridge which was exposed during this period by lower sea levels. These people are called the Paleo Indians, and the earliest accepted dates are those of the Clovis culture sites, some 13,500 years ago. Globally, societies were hunter-gatherers but evidence of regional identities begins to appear in the wide variety of stone tool types being developed to suit different environments.
The period between the end of the last ice age, 10,000 years ago to around 6,000 years ago, was characterised by rising sea levels and a need to adapt to a changing environment and find new food sources. The development of microlith tools began in response to these changes. They were derived from the previous Palaeolithic tools, hence the term Epipalaeolithic. However, in Europe the term Mesolithic (Middle Stone Age) is used, as the tools (and way of life) were imported from the Near East. There, microlith tools permitted more efficient hunting, while more complex settlements, such as Lepenski Vir developed based around fishing. Domestication of the dog as a hunting companion probably dates to this period.
The earliest known battle occurred during the Mesolithic period at a site in Egypt known as Cemetery 117.
The Neolithic, New Stone Age, was characterized by the adoption of agriculture, the so-called Neolithic Revolution, the development of pottery and more complex, larger settlements such as Çatal Hüyük and Jericho. The first Neolithic cultures started around 7000 BC in the fertile crescent. Agriculture and the culture it led to spread to the Mediterranean, the Indus valley, China and Southeast Asia.
Due to the increased need to harvest and process plants, ground stone and polished stone artifacts became much more widespread, including tools for grinding, cutting, and chopping. The first large-scale constructions were built, including settlement towers and walls, eg: Jericho and ceremonial sites, eg: Stonehenge. These show that there was sufficient resources and co-operation to enable large groups to work on these projects. To what extent this was a basis for the development of elites and social hierarchies is a matter of on-going debate. Although some late Neolithic societies formed complex stratified chiefdoms similar to Polynesian societies such as the Ancient Hawaiians, most Neolithic societies were relatively simple and egalitarian though Neolithic cultures were noticeably more hierarchical than the Paleolithic cultures that preceded them and Hunter-gatherer cultures in general. The earliest evidence for established trade exists in the Neolithic with newly settled people importing exotic goods over distances of many hundreds of miles. Skara Brae located on Orkney island off Scotland is one of Europe's best examples of a Neolithic village. The community contains stone beds, shelves and even an indoor toilet linked to a stream.
Near the end of the Wisconsin glaciation, 15,000 to 9,000 years ago, the Megafauna occurred in Asia, Europe, North America and Australia. This was the first Holocene extinction event. This event possibly forced modification in the dietary habits of the humans of that age and with the emergence of agricultural practices, plant-based foods also became a regular part of the diet. This extinction may have been caused by humans over hunting wild game animals such as the Wooly mammoth although other scientists believe that the megafauna extinction was instead caused by climate change.
The first wine-tasting may have occurred when Paleolithic humans slurped the juice of naturally fermented wild grapes from animal-skin pouches or crude wooden bowls.|||William Cocke|National Geographic News
Around 2 million years ago, Homo habilis is believed to have constructed the first man-made structure in East Africa, consisting of simple arrangements of stones to hold branches of trees in position. A similar stone circular arrangement believed to be around 500 thousand years old was discovered at Terra Amata, near Nice, France. Several human habitats dating back to the Stone Age have been discovered around the globe, including:
Rock paintings were painted on rock and were more naturalistic depictions than petroglyphs. In paleolithic times, the representation of humans in cave paintings was rare. Mostly, animals were painted: not only animals that were used as food but also animals that represented strength like the rhinoceros or large cats (as in the Chauvet Cave). Signs like dots were sometimes drawn. Rare human representations include handprints and half-human/half-animal figures. The Cave of Chauvet in the Ardèche département, France, contains the most important preserved cave paintings of the paleolithic era, painted around 31,000 BC. The Altamira cave paintings in Spain were done 14,000 to 12,000 BC and show, among others, bisons. The hall of bulls in Lascaux, Dordogne, France, is one of the best known cave paintings from about 15,000 to 10,000 BC.
The meaning of the paintings remains unknown. The caves were not in an inhabited area, so they may have been used for seasonal rituals. The animals are accompanied by signs which suggest a possible magic use. Arrow-like symbols in Lascaux are sometimes interpreted as calendar or almanac use. But the evidence remains inconclusive. The most important work of the Mesolithic era were the marching Warriors, a rock painting at Cingle de la Mola, Castellón in Spain dated to about 7,000–4,000 BC. The technique used was probably spitting or blowing the pigments onto the rock. The paintings are quite naturalistic, though stylized. The figures are not three-dimensional, even though they overlap.
Stone Age people believed that they were living at the center of the universe, that the earth was a small disc extending not far around known neighbors, mountains, or shorelines. They believed that all movement was of will. They saw insects moving by will. They saw the sun, the moon and the stars closer and they were and moving by will. For Stone Age people, will was spirit, and they saw their world as filled with many spirits. (or to use another word gods) This was the original polytheism.
When a person saw his reflection in the water he believed he was seeing his spirit the invisible would be made visible by the magic of the water.Seeing the lifeless bodies of those who had died. People believed the spirit of that person had left their body and gone to an invisible world where the spirits of the dead were not to be seen. They believed spirit lived all around them.
All anthropologists would agree that the negative use of the terms "primitive" and "stone age" to describe tribal peoples has serious implications for their welfare.||||BBC News
The image of the caveman is commonly associated with the Stone Age. For example, the 2003 documentary series showing the evolution of humans through the Stone Age was called Walking with Cavemen, although only the last programme showed humans living in caves. While the idea that human beings and dinosaurs coexisted is sometimes portrayed in popular culture in cartoons, films and computer games, such as The Flintstones and One Million Years B.C., the notion of primates and dinosaurs co-existing is not supported by any scientific evidence.
Other depictions of the Stone Age include the best-selling Earth's Children series of books by Jean M. Auel, which are set in the Palaeolithic and are loosely based on archaeological and anthropological findings. The 1981 film Quest for Fire by Jean-Jacques Annaud tells the story of a group of humans searching for their lost fire.
The phrase "bomb them back into the Stone Age", was made by then Chief of Staff, US Air Force General Curtis E. Lemay, when in 1965, he made the statement towards the North Vietnamese, during the Vietnam War; "They've got to draw in their horns and stop their aggression, or we're going to bomb them back into the stone age." The gist of that statement implied a fierce aerial attack that would have utterly destroyed its target's infrastructure, forcing its survivors to revert to primitive technology in order to survive.
