- Stone Age
Stone tools were made from a variety of different kinds of stone. For example, flintand chertwere shaped (or "chipped") for use as cutting tools and weapons, while basaltand sandstonewere used for ground stonetools, such as quern-stones. Wood, bone, shell, antlerand 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 technologyinnovations characterize the later Chalcolithic(Copper Age), Bronze Ageand Iron Age.
The period encompasses the first widespread use of
technologyin human evolutionand the spread of humanityfrom the savannas of East Africato the rest of the world. It ends with the development of agriculture, the domesticationof certain animals and the smeltingof copper oreto produce metal. It is termed "pre"historic, 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 Worsaaein 1859 through his work with Danish kitchen middens that began in 1851. [ [http://search.eb.com/eb/article-9077514 Worsaae, Jens Jacob Asmussen] ." Encyclopædia Britannica. 2008. Encyclopædia Britannica Online. 11 Apr. 2008] The subdivision into the Palaeolithic, Mesolithicand Neolithicperiods that still is in use today, was made by John Lubbockin 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 Stone Age in archaeology
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-
smeltingtechnology, 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 hominidtool-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 analysisis 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 reductionof 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.
Modern use of the term
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, settlementor religionand 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 charlotte Europe, and that it is inconvenient to use it in relation to regions such as some parts of the Americasand Oceania, where farmersor hunter-gatherers used stone for tools until European colonisationbegan. 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, silveror 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 metalworkingtechnology allowed bronze(copper and tinor 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 Eastand southeastern Asian regions progressed past Stone Age technology around 6000 BC. Europe, and the rest of Asiabecame post-Stone Age societies by about 4000 BC. The proto-Inca cultures of South Americacontinued 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
Neolithicsites. This "transition" period is known as the Copper age or Chalcolithic. It was a short and more a regional development, because alloying tinwith copper began quite soon, except in regions lacking tin. Ötzi the Icemanfor instance, a mummyfrom 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.
three-age systemdivides human technological prehistoryinto three periods:
* The Stone Age
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
periodizationof the Stone Age stretches from the Paleolithic to the Neolithic in the following scheme (crossing an epoch boundary on the geologic time scale):
Pleistoceneepoch (highly glaciated climate)
Holoceneepoch (modern climate)
* Historical period (written record begins)
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.

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.cite book | author=McClellan|url=http://books.google.com/books?id=aJgp94zNwNQC&printsec=frontcover#PPA11 | title=Science and Technology in World History: An Introduction| location=Baltimore, Maryland | publisher=JHU Press | year=2006 | id=ISBN 0801883601 [http://books.google.com/books?id=aJgp94zNwNQC&printsec=frontcover#PPA8 Page 6-12 ] ] 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.

Near the end of the
Pliocene epochin Africa, an early ancestor of modern humans, called " Homo habilis", developed the earliest known stone tools. These were relatively simple tools known as choppers. "Homo habilis" is presumed to have mastered the Oldowanera tool case which utilized stone flakes and cores. This industry of stone tools is named after the site of Oldupai Gorgein Tanzania. These humans likely subsisted on scavenged meat and wild plants, rather than hunted prey. Around 1.5 million years ago, a more evolved human species, " Homo erectus", appeared. "H. erectus" learned to control fire and created more complex chopper tools, as well as expanding out of Africa to reach Asia, as shown by sites such as Zhoukoudianin China. By 1 million years ago, the earliest evidence of humans in Europe is known, as well use of the more advanced handaxetool.
This period is most well-known as being the era during which the
Neanderthals lived (c. 120,000–24,000 years ago). The stone artefact technology of the Neanderthals is generally known as the Mousterianor more precisely Neandertal traits was found also in younger Châtelperronian, Aurignacianand Gravettianarcheological cultures. The Neanderthals traits eventually disappeared from the archaeological record, replaced by modern humans traits which first appeared in Ethiopiaaround 120,000 years ago although often identified as Archaic Homo sapiens. Neanderthals nursed their elderly and practised ritualburial indicating an organised society. The earliest evidence ( Mungo Man) of settlement in Australiadates to around 40,000 years ago when modern humans likely crossed from Asia by hopping from island to island. Middle Palaeolithic peoples demonstrate the earliest undisputed evidence for artand other expressions of abstract thought such as intentional burial of the dead.
From 35,000 to 10,000 years ago (the end of the
last ice age) modern humans spread out further across the Earthduring 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 bridgewhich 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 culturesites, 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
microlithtools 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 Virdeveloped based around fishing. Domestication of the dogas a hunting companion probably dates to this period.
The earliest known battle occurred during the Mesolithic period at a site in Egypt known as
Neolithic, New Stone Age, was characterized by the adoption of agriculture, the so-called Neolithic Revolution, the development of potteryand more complex, larger settlements such as Çatal Hüyükand 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, Chinaand 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:
Jerichoand 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.

Food and drink
Foodsources of the hunter-gathererhumans of the Stone Age included both animals and plants that were part of the environment in which these humans lived. These humans liked animal organ meats, including the livers, kidneys and brains. They consumed little dairy productor carbohydrate-rich plant foods like legumes or cereal grains. They also ate leaves and roots. They hunted animals.Fact|date=December 2007 Large seeded legumes were part of the human diet long before the neolithicagricultural revolution as evident from archaeobotanical finds from the Mousterianlayers of Kebara Cave, in Israel.cite journal |author=Efraim Lev, Mordechai E.

Near the end of the
Wisconsin glaciation, 15,000 to 9,000 years ago, the Megafaunaoccurred in Asia, Europe, North Americaand 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 mammothalthough other scientists believe that the megafauna extinction was instead caused by climate change.
Shelter and habitat
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:
* A tent-like structure inside a cave near the
Grotte du Lazaret, Nice, France.
* A structure with roof supported with timber, discovered in
Dolni Vestonice, Czechoslovakia, dates to around 23,000 BC. The walls were made of packed clay blocks and stones.
* Many huts made of
mammothbones were found in Eastern Europeand Siberia. The people who made these huts were expert mammoth hunters. Examples have been found along the Dnieprriver valley of Ukraine, including near Chernihiv, in Moravia, Czech Republicand in southern Poland.
* An animal hide tent dated to around 15000 to
10000 BC, in the Magdalenian, was discovered at Plateau Parain, France.
Megalithic tombs, multi-chambered and dolmens, single-chambered, were graves with a huge stone slab stacked over other similarly large stone slabs. They have been discovered all across Europeand Asiaand were built in the Neolithic. Several tombs with copper and bronze tools have also been discovered, illustrating the problems of attempting to define periods based on technology.
Pre-historic artcan only be traced from surviving artefacts. Prehistoric musicis inferred from found instruments, while parietal artcan be found on rocks of any kind. The latter are petroglyphs and rock paintings. The art may or may not have had a religious function.
Petroglyphs appeared in the New Stone Age, commonly known as Neolithic period. A Petroglyph is an abstract or symbolic image recorded on stone, usually by prehistoric peoples, by means of "carving", pecking or otherwise incised on natural rock surfaces. They were a dominant form or pre-writing symbols used in communication. Petroglyphs have been discovered in different parts of the world, including Asia(Bhimbetka, India), North America( Death Valley National Park), South America( Cumbe Mayo, Peru), and Europe (Finnmark, Norway).
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
rhinocerosor 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 Spainwere 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
calendaror almanacuse. But the evidence remains inconclusive.Fact|date=July 2008 The most important work of the Mesolithic era were the marching Warriors, a rock painting at Cingle de la Mola, Castellónin 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.Fact|date=July 2008
tone Age rituals and beliefs
Modern studies and the in-depth analysis of finds dating from the Stone Age indicate certain rituals and beliefs of the people in those prehistoric times. It is now believed that activities of the Stone Age humans went beyond the immediate requirements of procuring food, body coverings, and shelters. Specific rites relating to death and burial were practiced, though certainly differing in style and execution between cultures. Several Stone Age-dated sites of the in different parts of the world indicate traces of
dancing, dancing in files, and initiation rites.Fact|date=July 2008
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.
slangterm, "Stone Age" is sometimes used to describe living tribal peoples, to imply "backwardness". In 2007, the Association of Social Anthropologists called the term "offensive" when applied to any living peoples, saying such language has been used "as a pretext for depriving such peoples of land and other resources".
The image of the
cavemanis commonly associated with the Stone Age. For example, the 2003 documentary seriesshowing 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 Palaeolithicand are loosely based on archaeological and anthropological findings. The 1981 film" Quest for Fire" by Jean-Jacques Annaudtells 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 ForceGeneral 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.
