21.1 Introduction

The Paleolithic is the term applied to a very broad, early period of human prehistory beginning with the first archeological evidence of stone toolmaking approximately 2.6 Ma, through to the end of the Pleistocene epoch about 10,000 years ago, when the last continental glaciation receded. It is important to appreciate that over 99% of human technological development took place during the Paleolithic. The Paleolithic thus constitutes the bulk of the time span of human technological development and human prehistory and documents the emergence and evolution of the genus Homo. The term is applied primarily to prehistoric developments in the Old World, as the New World's earliest archeological evidence appears only toward the very end of Paleolithic times, during the last phases of the terminal Pleistocene glaciation. In the New World, however, the period of Late Ice Age hunter-gatherers is often referred to as “Paleoindian,” and is contemporaneous with the last few thousand years of the Paleolithic in the Old World.

“Paleolithic” literally means the “Old Stone” (paleo = old, lithic = stone) Age, as it represents the earliest phases of human technological development when the vast majority of the tools represented in the archeological record were made of stone. At the end of the Pleistocene, the Paleolithic is followed by the later phases of the Stone Age, the Mesolithic and then the Neolithic. During the Mesolithic (in some regions referred to as the “Epipaleolithic”), stone technologies continued to evolve as stone tool-using hunter-gatherers adapted to changing environments of the current (Holocene) epoch, sometimes characterized by small (microlithic) stone tools. During the last phase of the Stone Age, often referred to as the Neolithic (or “New Stone” Age), a transition occurred from hunting-gathering to a more settled way of life based on food production (agriculture and herding), but stone continued for some time to be used for tools (such as ground axes, projectile points, and sickles).

The Paleolithic is traditionally divided into three major subdivisions: (1) the Early Paleolithic (also sometimes called the Lower Paleolithic) or Early Stone Age (ca. 2.6 Ma to 250,000 years ago; (2) The Middle Paleolithic or Middle Stone Age (ca. 250,000–30,000 years ago); and the Late Paleolithic (also Upper Paleolithic) or Later Stone Age (ca. 40,000–10,000 years ago). The “Lower”/“Middle”/“Upper” designations for the Paleolithic stages were developed in Europe in the late nineteenth and earlier twentieth centuries, based primarily on diagnostic artifact types and technological patterns observed in the stratigraphic and cultural sequences in various regions of Europe. More recently, with the appreciation that other parts of the world did not follow the precise cultural-historical sequence of Europe, many researchers have put less formal emphasis on these designations in favor of the more neutral terms “Early”/“Middle”/“Late” on a worldwide scale. This latter terminology will be used here.

For the first hundred years of Paleolithic research, these Paleolithic subdivisions were used to express a general chronological sequence (a relative chronology) without a firm sense of how many years ago each phase began or ended (an absolute chronology). During the past half-century, however, radiometric dating techniques have allowed the development of a more precise chronological framework for this Paleolithic sequence worldwide, with approximate times for the beginning and end of each phase.

Change from one stage of the Paleolithic to the next, however, does not always entail an immediate or complete turnover in artifact types, though it does generally represent an obvious and perceptible shift in the types of artifacts dominating the archeological tool assemblages, and often a corresponding shift in the dominant methods used in making these tools. For instance, while modified flake tools are present at a number of Lower Paleolithic sites, they become the dominant artifact form, often with consistent or repeated shapes, at many Middle Paleolithic sites. There is also some regional variation in the absolute chronology of the sequence, with evident technological transitions in some regions occurring earlier or later than in other regions. For instance, the transition from the Middle Paleolithic/Middle Stone Age to the Late Paleolithic/Later Stone Age happens somewhat earlier in some regions than in others.

21.2 Perspectives on early stone tools

The earliest prehistoric archeological record is now approximately 2.6 Myr old, based on the recognition of flaked stone artifacts in securely dated deposits in East Africa. The fossil record of bipedal hominids, however, goes back at least 6 Ma, several Myr before the first appearance of stone tools (see Volume 3 Chapter 5). On the basis of modern primate analogs, especially from chimpanzees, a range of tools and tool-using behaviors might be postulated for hominid populations prior to 2.6 Myr. Such hypothetical early tool use likely involved highly perishable, organic raw materials that provide no enduring, visible archeological record.

A handful of nonhuman species have been documented to show some minimal use of tools in the wild, including sea otters, birds (such as crows, finches, Egyptian vultures), and even mud wasps. Aside from humans, however, the only other animals showing habitual use of a variety of tools for a variety of purposes are our closest living relatives, the chimpanzees. What is more, chimpanzee toolmaking and tool-using skills appear to be learned over several years, suggesting a simple culturally transmitted system.

We now know that there is variability among different chimpanzee groups in the sets of tools they commonly use, showing cultural variation among chimpanzees in their tool kits. Modern chimpanzee tool use includes nut cracking with stone and wood hammers and anvils, termite fishing, and ant dipping with sticks or grass stems, and using chewed-up wads of leaves as sponges to obtain water or for self-cleaning. Although some chimpanzee tools consist of unmodified objects used for a particular task, chimpanzees do intentionally modify or shape some of their tools, such as the sticks and grasses used for termite fishing or ant dipping, and the chewed leaves used as sponges.

Deliberately manufactured stone artifacts in the early archeological record represent the earliest evidence of tool production by early hominids. As such, they reveal the development of a reliance on stone tool use in early hominid adaptation by at least 2.6 Ma. Although stone tool use may have been affected by seasonal, environmental, or other opportunities, the archeological record reveals a consistent manufacture of stone tools that persisted from this time onward until recent times.

Early stone artifacts clearly indicate a number of interesting behavioral characteristics of these early hominids: they selected stone raw materials at specific locations, transported manufactured artifacts and unmodified stone from one place to another on the paleolandscape, and discarded artifacts (and sometimes parts of animal carcasses) in distinct concentrations at many localities some distance from the raw material sources. Moreover, the manufacturing process used to produce early stone artifacts is one that is not observed in any nonhuman animal, even among chimpanzees, highlighting the novelty of behavioral innovation in the early stone toolmakers. Although early stone tools are admittedly simple and do not show elaborate shaping, they represent clear evidence of a new and unusual behavior pattern: the deliberate, controlled fracture of rock through percussive blows.

Technological patterns seen in early stone artifacts indicate they were produced primarily through a technique sometimes called “free hand, hard hammer percussion.” This involves hitting one rock (the hammer) against another (the core) to bring about controlled fracture of the core (called conchoidal fracture, as the shock waves can produce radiating, shell-like ripples in finer-grained materials) and produce numbers of sharp pieces called flakes, a process called flaking or knapping. Experiments have shown that a main objective of early stone toolmaking was likely the production of such sharp flakes to use as cutting tools. Thus, a primary tool in the early hominid tool kit was likely the sharp-edged flake, and many of the cores found at early sites were likely by-products of the toolmaking process.

Early stone toolmaking hominids were consistently producing such fractured stones at a number of early site localities. Early Paleolithic sites often involve dozens of flaked cores and thousands of flake products. Analysis of early archeological materials often reveals extensive, controlled flaking of cores, involving rotation and manipulation to produce a series of flakes from the same piece of stone. Such fine core manipulation and exploitation is observable at even the very earliest Stone Age sites at Gona in Ethiopia, showing consistent, controlled, and skillful flaking of cores by 2.6 Ma.

With such skillful flaking observable among early hominid toolmakers on the one hand and the diverse tool-using and toolmaking cultures observable in chimpanzees on the other, a natural question is whether the production of early stone tools represents skills beyond those seen in other apes. Although chimpanzees are known to use stones as hammers and anvils in nut-cracking activities in West Africa, wild chimpanzee tool manufacture does not involve the intentional percussive flaking of stone, and wild chimpanzees have not developed sharp-edged tools for cutting in their assorted tool kits. It has been possible, however, to explore through experiments how comparable toolmakings skills of early hominids are to those of apes in captivity. An essential question in such experiments is whether the toolmaking skills of early hominids represent a significant departure from an ape “substrate” of toolmaking ability, and what insights we might gain regarding early hominid cognitive abilities. Do early hominid toolmakers exhibit special cognitive or biomechanical skills or abilities, or do these emerge only much later in human biological and technological evolution?

Experiments were begun in 1990 teaching a bonobo (pygmy chimpanzee), Kanzi, to make and use stone tools (Figure 21.1 ). The experiment involved introducing a use for a stone tool for cutting and retrieving a foodstuff, initial demonstration (modeling) of stone tool manufacture, and a subsequent period of trial-and-error learning on Kanzi's part in both the toolmaking and tool-using operations. This experiment, which is still ongoing and now involves Kanzi's younger sister and her two young offspring as well, has clearly shown that apes can become adept at some aspects of stone toolmaking skills and produce recognizable artifacts comparable to some of those found at early sites. Now, however, after more than 15 years of this ongoing experiment, some distinct technological differences persist in the bonobos’ artifacts compared to artifact assemblages found at early Paleolithic sites. Some of these differences appear to reflect lesser skill in the bonobo toolmaker, perhaps reflecting lesser cognitive appreciation of particular facets of the toolmaking process (such as flaking sharper edges of the core, etc.), although others are likely related to biomechanical differences in the hand and arm of the apes.

Kanzi learned stone tool manufacture by modeling or imitation and then years of trial-and-error, and he uses his tools to cut open a container to obtain food. His stone toolmaking skills have improved since the start of this experiment in 1990. Many of his artifacts resemble those found at Oldowan sites, although overall his flakes and cores still show some important differences from those found at Early Paleolithic sites

This experiment highlights how skilled and adept early stone hominids were in their stone toolmaking by the time of the earliest known archeological occurrences 2.6 Ma. The skillfulness reflected in the earliest stone tools might indicate that even earlier stone technologies existed, yet undiscovered and perhaps rare on the paleolandscape, whose makers were not quite as proficient in flaking stone and who did not produce such a readily recognizable product. Or it may be that hominids were “preadapted” to efficiently flaking stone because of selection for other manipulative skills, which were later transferred to stone knapping when the need arose. The ape stone toolmaking experiments give important clues as to what technological characteristics might be found in such hypothetical “Pre-Oldowan” technologies.

21.3 Early Paleolithic

The Early Paleolithic comprises a long time interval, between 2.6 Ma and approximately 250,000 years ago. It not only includes this extremely large span of human prehistory but also encompasses, over time, sites across huge geographical distances, from southern Africa to eastern Asia. During this period of more than 2.25 Myr, profound evolutionary changes occurred among hominids, and some marked changes are observed in the archeological record in many parts of the Old World.

In Africa, where the Early Paleolithic is often referred to as the Early Stone Age, two industries have been recognized: (1) the first to appear, starting 2.6 Ma, the Oldowan Industry (named after Olduvai Gorge in Tanzania), consists of stone industries containing simple cores and flaked pieces, along with some battered artifacts such as hammerstones and (2) starting between 1.7 and 1.5 Ma, or approximately a Myr after the onset of Oldowan technology, the Acheulean Industry (named after the locality of St. Acheul in France) appears, with new, distinctive artifact forms in the form of relatively large bifacial tools (hand axes, cleavers, and picks).

21.3.1 Oldowan

The Oldowan is the first recognizable archeological record, with simple flaked and battered stone artifacts, sometimes found with cut-marked and broken animal bones, emerging around 2.6 Ma. Although similar types of simple lithic industries are found throughout time, archeologists usually use a cut-off of around 1 Ma when referring to the Oldowan Industrial Complex. The Oldowan coexisted for several hundred thousand years with the Acheulean hand axe industries, starting about 1.7 Ma. Oldowan sites are known first from Africa, and subsequently document the spread of hominids outside of Africa into parts of Eurasia, notably producing archeological sites in the Near East, the Republic of Georgia, and eastern Asia. These sites are found especially in tropical and subtropical climatic regimes, in particular grassland/woodland environments.

In East and North Africa, most Oldowan sites are open-air occurrences that are located along stream courses, in deltaic settings, or on lake margins. These were areas of close proximity to water and were depositional settings where sediments could build up over time. In South Africa, Oldowan artifacts are found in karstic limestone cave deposits and may have been carried there by hominids or brought in by natural forces such as slope wash or gravity. The high incidence of hominid bones in South African cave deposits (especially robust australopithecines) may be the result of predation and/or scavenging by carnivore such as leopards and hyenas.

Oldowan industries are contemporaneous with a number of bipedal hominid forms, including later australopithecines (Australopithecus garhi, A. aethiopicus, A. robustus, and A. boisei), whose cranial capacities ranged from about 400 to 550 cm3, and early forms of the more encephalized genus Homo (H. rudolfensis, H. habilis, H. ergaster/erectus), whose cranial capacities ranged from about 600 to 850 cm3. Although it is possible that all of these hominids used stone technology to a greater or lesser extent, many anthropologists believe that the genus Homo was probably a more habitual toolmaker and tool-user, as its brain size almost doubles in the first Myr of the Oldowan while its jaws and teeth tend to diminish in robusticity. By 1 Ma, only Homo ergaster/erectus was known in the human paleontological record, while the australopithecines became extinct. Interestingly, Homo ergaster/erectus appears to have much more modern limb proportions and stature relative to earlier hominids and is the first form clearly identified outside of Africa.

Oldowan industries are characterized by simple technologies (sometimes called Mode 1) consisting of cores made on pebbles or chunks (choppers, discoids, polyhedrons, heavy-duty scrapers, facetted spheroids), battered percussors (hammerstones and battered spheroids), debitage (flakes and fragments), and retouched pieces (scrapers, awls, etc.) (Figure 21.2 ). Common raw materials include volcanic lavas, quartz, and quartzite. The most common techniques for producing Oldowan artifacts were hard hammer percussion and bipolar technique (in which the core to be flaked is set on a stone anvil and hit with a stone hammer). At Olduvai Gorge, some technological trends have been observed through time, with later Oldowan sites showing higher frequencies of such artifact classes as scrapers and battered spheroids and lower frequencies of choppers. These sites are sometimes assigned to a “Developed Oldowan,” but such a designation is more difficult to apply elsewhere.

Microwear patterns on a small sample of Oldowan tools suggest that flakes were used for animal butchery, wood-working, and cutting soft plant matter. Experiments in using stone tools (Figure 21.3 ) have shown that Oldowan flakes can be used to efficiently process the carcasses of animals from the size of small mammals to elephants (Figure 21.4 ), and stone hammers could easily break bones for access to nutritious marrow and skulls for brain tissue. Choppers could have been used to chop branches to make spears or digging sticks, although many such Oldowan core forms were probably by-products of flake production. It is likely that a rich range of perishable organic material culture was also used, including containers of shell, horn, skin, or bark; wooden clubs and or throwing sticks; wooden spears or digging sticks (Figure 21.5 ); and horn or bone fragments as digging tools. In addition, a small sample of bone specimens from South African caves are polished and striated on their pointed end, suggesting that these may have been used as opportunistic digging tools to gain access to underground vegetable resources or insects such as termites.

Although evidence of fire has been found at a few Oldowan sites (in the form of reddened, baked sediments, burnt bones, or fire-cracked stone), it cannot be ruled out that natural agents, such as lightning strikes and brushfires, may have produced these fires. No clear architectural structures have been found at Oldowan sites, and it is possible that Oldowan hominids could have been sleeping in trees at night (perhaps building nests like chimpanzees) rather than on the ground in order to avoid predation by nocturnal carnivores.

It seems clear that these Oldowan hominids were concentrating lithic material and animal bones at favored locations on the landscape (a pattern not seen in nonhuman primates today), but the precise behavioral patterns that formed these concentrations are still debated. Interpretations for these concentrations include home bases or central foraging places, favored places due to proximity to shade, water, or food resources, intentional stone caches, and scavenged carnivore accumulations. It is also possible that Oldowan sites formed through more than one behavioral pattern. Cut marks and percussion marks/fractures on bones show that hominids were accessing meat and marrow resources from animal carcasses obtained through scavenging or hunting. The modified bones at Oldowan sites typically come from animals ranging in size from small mammals to those weighing hundreds of pounds. This is a scale of carnivory that is not seen in the nonhuman primate world and was most likely greatly facilitated through the use of stone tools.

At present, there is a debate as to whether hominids accessed larger animals through more marginal scavenging (getting the ravaged leftovers of carnivore kills) or rather had access to more complete carcasses through hunting or confrontational scavenging. In any case, the processing of larger animal carcasses could have significantly increased the diet breadth (and thus survivorship and reproductive success) of Oldowan hominids, although the majority of Oldowan hominid diet was likely derived from plant foods such as fruits, berries, nuts, edible leaves, and underground storage organs (roots, tubers, corms, and rhizomes). Carrying devices may have facilitated the collection and transport of dietary items that could be consumed at a later time.

Important Oldowan localities include Gona, Fejej, and the Omo valley in Ethiopia; East and West Turkana in Kenya; Olduvai Gorge in Tanzania; Sterkfontein and Swartkrans caves in South Africa; Ain Hanech and el-Kherba in Algeria; the lowest levels at Ubeidiya in Israel; and Dmanisi in the Republic of Georgia.

21.3.2 Acheulean

The Acheulean Industrial Complex is characterized by the presence of large bifacial hand axes and cleavers (sometimes called Mode 2 technologies), which are found from approximately 1.7 Ma to 250,000 years ago. These hand axe/cleaver industries are contemporaneous and sometimes regionally co-occurring with the simpler Oldowan-like (Mode 1) industries. Acheulean and contemporaneous Mode 1 industries are found throughout Africa and Eurasia, but classic hand axe and cleaver assemblages are especially characteristic of Africa, the Near East, the Indian subcontinent, and western Europe. Elsewhere, notably eastern Europe and most of eastern Asia, simpler Mode 1, Oldowan-like technologies are found. This was a period of major climatic change, with numerous cold/warm oscillations that would have especially affected northern latitudes of Eurasia. For most of this period, hominids would have flourished only during the warmer periods in these northern latitudes. Hominids extended their range from grasslands and woodlands of tropical and subtropical regions to cooler, more temperate climates during this period.

Contemporaneous hominid forms include Homo ergaster/erectus and the later, larger-brained Homo heidelbergensis (sometimes referred to as “early archaic Homo sapiens). Cranial capacities range from about 800 to 1,400 cm3, generally increasing over the time span of this period. In the early Acheulean, robust australopithecines (A. robustus and A. boisei) still existed, but most anthropologists do not regard these forms as plausible Acheulean toolmakers, and in any case they appear to have gone extinct by 1 Ma.

New elements in Acheulean industries (in addition to Mode 1, Oldowan-like artifacts that continue to be found) include hand axes, cleavers, picks, and knives (generically called “bifaces”) made either on large flakes struck from boulder cores or on larger cobbles and nodules. A range of well-made retouched tools, such as side scrapers, awls, and backed knives, are also common. Frequently used raw materials include fine-grained lavas, quartzites, and flints. Earlier, cruder bifaces were produced by hard hammer percussion (Figure 21.6 ), while later more refined bifaces were probably finished by the soft hammer technique, in which a softer material, such as wood, bone, ivory, antler, or even soft stone, was used as a percussor, producing thinner, more invasive flakes (Figure 21.7 ). Prepared core techniques, notably the Levallois tortoise core technique (in which a large, predetermined flake is removed from the upper surface of a discoidal core), and, more rarely, early blade production, are found in some later Acheulean industries. Sharpened wooden spears are known from later Acheulean times, as at Schöningen in Germany and Clacton in England, suggesting that more formal hunting weaponry was established as part of a regular subsistence pattern by at least this time if not earlier.

These artifact forms, made on large flakes or cobbles, show definite shaping to leave a sharp working edge, especially toward the tip end of the hand axe and the bit of the cleaver, with the lower part of the tool shaped or left natural to serve as a handle. They usually show some, though relatively low, degree of symmetry in their plan view and their cross section and were made by hard hammer percussion

The fact that Acheulean and contemporaneous hominids successfully occupied cooler, more temperate latitudes suggests that they were better adapted to such cooler conditions. Use-wear patterns on side scrapers indicate that many of these tools were used to scrape hides, strongly suggesting that animal skins were being used for simple clothing, blankets, and/or tent or hut coverings. Evidence of fire in the form of charcoal or ash layers is occasionally seen in later Acheulean times but is by no means widespread in the archeological record during this period. There is no definitive evidence of architectural structures during Acheulean times, although arguments have been made in this regard. Sites are found in numerous caves and rockshelters as well as many open-air sites.

Hand axes and cleavers in particular, indicate the ability to impose bilateral symmetry on lithic materials. This clearly shows higher cognitive abilities and motor skills than are manifested in the Oldowan. Even modern humans who learn to make stone tools normally require considerable apprenticeship before they can produce well-made hand axes and cleavers. Although there is a wide range of hand axe forms through time and space, it is common that at certain Acheulean sites there are recurrent shapes and sizes, as if there were stylistic norms of production among their makers. Presence of ochre at some sites and, occasionally, incised bone may indicate the emergence of proto-symbolic behavior as well.

Important Acheulean sites/localities include Konso-Gardula, Middle Awash, Melka Kunturé, and Gadeb in Ethiopia; Olduvai Gorge and Peninj in Tanzania; Olorgesailie and Isenya in Kenya; Kalambo Falls in Zambia; Elandsfontein and Montagu Cave in South Africa; Ternifine in Algeria; Ubeidiya and Gesher Benot Ya'aqov in Israel; Swanscombe, Hoxne, and Boxgrove in England; St. Acheul and Terra Amata in France; and Torralba and Ambrona in Spain. Important contemporaneous Mode 1 localities include Atapuerca (TD6) in Spain, Arago Cave in France, Clacton in England, Bilzingsleben and Schöningen in Germany, Vérteszöllös in Hungary, Isernia in Italy, and the Nihewan Basin and Zhoukoudian (“Peking Man”) cave in China.

21.4 Middle Paleolithic/Middle Stone Age

The Middle Paleolithic industries of Europe, the Near East, and North Africa (sometimes called the “Mousterian” after the site of Le Moustier in France) and Middle Stone Age industries of sub-Saharan Africa are found between approximately 250,000 and 30,000 years ago. They are found in tropical, subtropical, temperate, and even periglacial climatic regimes. During this time, hominids extended their ranges to most environmental zones of Africa and Eurasia except harsh deserts, the densest tropical forests, and extreme northern or arctic tundras. It appears that hominids were somehow able to cross the water between Southeast Asia and Australia, then attached to New Guinea and Tasmania, by late in this period. Contemporary hominid forms include those often designated as archaic Homo sapiens (including the Neandertals of Europe and the Near East) and anatomically modern humans.

Hand axes and cleavers tend to be less common (although toward the end of the Middle Paleolithic of Western Europe, smaller, well-made hand axes are found), and the emphasis of these stone industries is on retouched forms made on flakes (such as side scrapers, denticulates, and points) become numerous in many of these assemblages (Figure 21.8 ). Hard hammer and soft hammer techniques were common during this period. Many of these industries exhibit prepared core methods, notably the Levallois technique for more controlled production of flakes, points, and sometimes blades. Wooden spear technology continues from the Acheulean (as seen at Lehringen, Germany, where a spear with a fire-hardened tip was associated with an elephant carcass), and stone points with tangs or thinned bases suggest that these forms may have been hafted onto spear shafts, suggesting the development of composite tools. Rare bone points are also known from this time.

Fire and hearth structures are much more common during this period, although clear architectural features outlined by stones or bones are rare. Sites are numerous in caves and rockshelters, as well as open-air sites on plateaus and along river floodplains.

Occasional perforated and grooved shells and teeth at a few sites imply the emergence of some personal adornment, and along with the infrequent presence of ochre or, more rarely, engraved bone as well as a number of well-documented burials, suggest at least some symbolic component to hominid behavior during this period of the Paleolithic.

Important Middle Paleolithic/Middle Stone Age sites include Combe Grenal, Pech de L'Azé, Le Moustier, La Quina, and La Ferrassie in France; Krapina in Croatia; Cueva Morin in Spain; Tabun, Skhul, Kebara, Amud, and Qafzeh in Israel; Shanidar in Iraq; Dar es Soltan in Morocco; Bir el Ater in Algeria; Haua Fteah in Libya; Kharga Oasis in Egypt; Diré-Dawa, Omo-Kibish, and Middle Awash in Ethiopia; Enkapune Ya Muto, Prospect Farm, and Kapthurin in Kenya; Kalambo Falls, and Twin Rivers in Zambia; and Florisbad, Border Cave, Klasies River Mouth Cave and Die Kelders Cave in South Africa.

21.5 Late Paleolithic

The Late Paleolithic (often called Upper Paleolithic in Europe and Later Stone Age in Africa) is found between 40,000 and 10,000 years ago, at which time the last glaciation receded. This period of human prehistory overlaps and is contemporaneous with the end of the Middle Paleolithic/Middle Stone Age in some regions. During this time, humans inhabited tropical, subtropical, temperate, desert, and arctic climates; occupied present-day Australia, New Guinea, and Tasmania after crossing significant bodies of water; and, late in this period, spread to the Americas via the Bering Straits. Late Paleolithic industries are almost always associated with anatomically modern humans (Homo sapiens sapiens), but some early Upper Paleolithic sites in Europe are also contemporaneous with the last populations of Neandertals there.

Late Paleolithic stone industries are often characterized by blade technologies, elongated flakes produced by soft hammer or indirect percussion, in which a punch is placed on the edge of a blade core and struck with a percussor. These blades were then made into a variety of tool forms, including end scrapers, burins, and backed knives (Figure 21.9 ). Some Late Paleolithic technologies emphasized bifacial points, such as the Solutrean of Spain and France, and the Paleoindian occurrences of the New World (Clovis and Folsom). Such points may have been produced by soft hammer technique or by pressure flaking, in which small flakes are detached by directed pressure rather than by percussion. Some raw materials appear to have been heat-treated to make them easier to work. Other Late Paleolithic technologies emphasized bladelets (small blades) and geometric microliths, which were hafted as composite tools into a range of projectiles and cutting tools. These microlithic technologies are characteristic of the Later Stone Age of Africa as well as some parts of central and eastern Asia.

A diagnostic element of many Late Paleolithic industries is an emphasis on nonlithic materials for tools, including bone, antler, and ivory, made into a range of artifact forms such as points, needles, spear-throwers, shaft straighteners, and harpoons. Hooked spear-throwers are essentially mechanical devices to increase the velocity and/or distance of a projectile, and thus represent a significant advance in hunting technology or weaponry. The small size of some points and microliths toward the end of the Late Paleolithic suggest the development of bow and arrow technology, and arrows are preserved at Stellmoor, Germany.

Several human sculptures from the Late Paleolithic suggest clothing such as hooded parkas, headdresses, and aprons. The development of bone and antler needles also suggests that sewed clothing was common after 20,000 years ago, and recently discovered impressions on fired clay fragments from the Czech Republic indicate woven textiles, presumably of plant material.

Controlled use of fire appears to be a universal trait during this period, with hearths sometimes lined with stones. Architectural features are much more common than in earlier periods, with hut structures delineated by stone or bone patterns, by postholes, and sometimes with hearth structures and other apparent activity areas within (such as toolmaking or tool-using). Sites tend to be more numerous and have denser concentrations of materials, suggesting larger populations and more regular habitation of sites.

One of the most distinctive characteristics of the Late Paleolithic is the proliferation of symbolic expression in art and personal adornment (Figure 21.10 ). This can be seen in the naturalistic representation of animals and, more rarely, humans in painting and sculpture as well as in the more abstract geometric designs. A variety of media was employed for artistic expression, including use of charcoal, pigment paints, antler, bone and ivory, and clay, as well as a diversity of techniques, including drawing, painting, engraving, carving, and modeling. Personal adornments are sometimes numerous, manifested in beads or pendants of shell, bone, tooth, antler, ivory, and stone. This proliferation of symbolic expression, best seen in the European Upper Paleolithic, has sometimes been referred to as the “Creative Explosion.” Some of these artistic manifestations, particularly paintings, drawings, and engravings, are located in deep, hard-to-access recesses of caves, suggesting a ritualistic and religious aspect to this symbolism. In view of the complexity of the material culture of this period and its well developed symbolic component, it is likely that modern human language abilities were fully developed by this time, if not before.

Late Paleolithic burials are more common and more elaborate than in the Middle Paleolithic. Men, women, and children were sometimes interred with rich grave goods, including stone tools, jewelry, and bone/antler/ivory artifacts. Again, this suggests an important symbolic component and a probable belief in an afterlife, in other words, something akin to a spiritual belief and a religion.
