The Times History of the World

FROM c. 200,000 YEARS AGO

THE SPREAD OF MODERN HUMANS

DNA studies have revealed that the first anatomically modern humans—Homo sapiens—arose in Africa between 200,000 and 140,000 years ago. Though much has still to be discovered about their origins and dispersal, by almost 28,000 years ago Homo sapiens had become not only the sole human species but the first truly global one.

The earliest modern-looking human skulls yet found are about 130,000 years old and come from the Omo basin in Ethiopia and Klasies River Mouth in southern Africa, the latter one of the best-researched sites of early human habitation. Perhaps 100,000 years ago, these early populations began to disperse, migrating northwards out of Africa. These migrations were followed by a process known as “bottlenecking” in which population levels among the dispersed peoples remained small for thousands of years. It is possible that a contributory factor to bottlenecking was the eruption of Toba in northwest Sumatra 71,000 years ago, an environmental catastrophe on an extraordinary scale: parts of India were covered with ash up to 3m (10ft) deep, global temperatures were lowered for a millennium. At the same time, the restricted populations generated by bottlenecking had the side effect of encouraging rapid changes in genetic structures thereby increasing the pace of evolutionary change.

Archaeological and genetic evidence then point to a further rapid expansion of modern human populations about 50,000 years ago. The archaeological evidence in particular highlights growing sophistication and the mastery of a wide and increasing range of skills. In some regions, lighter, multi-component weapons have been found, including spears made from skilfully produced stone blades fixed to wooden shafts and handles. There is evidence, too, of textiles and baskets, and of more orderly layouts of camp-sites, including cold-weather dwellings and underground food stores. Trading networks also increased dramatically. Raw materials, particularly stone, which had previously been traded over distances of less than 80km (50 miles), were now traded over several hundreds of kilometres (there is good evidence for this in eastern Europe).

THE NEANDERTHALS

Homo sapiens was by no means the only human species in the world of 50,000 years ago. In East and southeast Asia lived the descendants of those Homo erectus populations who had colonized the region over a million years earlier. Among other human populations the best known are the Neanderthals, distinguished from modern humans by their distinctive large and low-crowned heads with prominent brows and big teeth and powerful stocky bodies well adapted to cold. By contrast, the incoming modern people had an African body pattern—slender with long legs and small torsos—that copes better with heat stress. The Neanderthals had brains as large as modern humans and were in many ways highly successful. They adapted well to a wide range of habitats and climates ranging from the relatively arid Middle East to the cold of central Europe; their use of tools was sophisticated; and they were effective hunters of animals in prime condition such as bison, horse and reindeer. The burial of their dead, often with some elaboration, also indicates signs of a recognizably modern humanity. They almost certainly had language, too. But what the Neanderthals seem not to have possessed is the degree of social flexibility and cultural tradition that more than any other characteristic singles out Homo sapiens and explains our ultimate success in becoming the only global hominine.

This social and intellectual sophistication reveals itself in a number of ways but the result of it was almost always the same: the evolution of more complex social relations which allowed early humans to thrive in a much wider range of habitats and societies than previous hominine species had managed before. Whether living in large or small groups, Homo sapiens was able to overcome its environment to an unprecedented degree. The most striking evidence is provided by the wide variety of artefacts that have been discovered: engraved stones, ornaments, figurines, exotic shells, amber and ivory and, most famously, cave paintings. That the latter were frequently inaccessible and could have been seen only with ladders and artificial light suggests that a variety of factors motivated their creators. Whatever the explanation, these early works of art are an evocative monument to the humanity of these early hunters.

It is significant that the Neanderthals had almost no cultural traditions of this kind. A few incised bones have been found; similarly, the very occasional exotic piece of raw material occurs. By almost 28,000 years ago, both Neanderthals and Homo erectus were extinct. Modern humans had already colonized Australia 20,000 years before, and were set to colonize the Americas before 12,000 years ago. Henceforth modern humans were the sole surviving hominine in the world.

20,000 TO 10,000 BC

THE ICE AGE WORLD

By 10,000 years ago, humans had colonized almost the whole of the habitable world. It was an achievement made in the face of the last of a series of Ice Ages, when vast sheets of ice periodically advanced and retreated. The human species today is the product of this long process of adaptation to the varied conditions of the Ice Ages.

There have been eight Ice Ages in the last 800,000 years, each interspersed with warmer periods from 30,000 to 10,000 years known as interglacials, brief and extreme parts of this cycle. The Ice Ages were periods of exceptional cold away from the equator. Ice sheets advanced across the frozen wastes of the northern hemisphere as temperatures fell by up to 15 degrees centigrade. With so much of the earth’s water locked into the ice sheets, sea levels fell by up to 150m (500ft). As they did so, land bridges appeared, linking many major land areas and present-day islands into larger continental land masses.

Equatorial regions were also affected: as rainfall diminished, half the land area between the tropics became desert. With each advance of the ice, the plants and animals of the northern hemisphere withdrew to warmer latitudes. As the ice retreated, so they moved northwards again. Humans, too, must have migrated with these changing climates. Yet despite the extremes of cold, the human species continued to develop, spreading from its original African homeland to east and southeast Asia and to Europe. Mastery of fire and the invention of clothing were crucial to this achievement, as were new social and communication skills.

ICE AGE HUMANS

The height of the last Ice Age or LGM (last glacial maximum) was reached about 20,000 years ago. As the ice expanded, human populations contracted into a small number of more favourable habitats. Across almost the whole of the Eurasian landmass between the ice to the north and the deserts to the south, from the glacial cul-de-sac of Alaska to southern France, productive grasslands and steppes were created. Rich in seasonal grasses, they sustained large herds of mammoth, bison, horse and reindeer, all of them important food sources for Palaeolithic (the period of the emergence of modern man, about 2.5–3 million years ago to 12,000 BC) hunters.

Much the same sort of habitat seems to have developed in North America. By the time modern humans migrated there about 15,000 years ago, the rolling grasslands were teeming with animal life: giant bison with a six-foot horn spread; towering beaver-like creatures called casteroides; camels; ground sloths; stag moose; two types of musk-oxen; several varieties of large, often lion-sized cats; mastodons; and three types of mammoth. So effectively did the new human population hunt them that by about 10,000 years ago almost all of them were extinct, including the horse, re-introduced to the New World only by Europeans following in the wake of Columbus.

South of the Eurasian mammoth steppe lay an extensive zone of drier conditions. Indeed parts of the Sahara, the Near East and India became almost entirely arid, forcing their populations along permanent watercourses such as the Nile. Similar patterns of settlement are found in Australia, where cemeteries discovered along the Murray River bear marked resemblances to those along the Nile.

Modern humans were late arrivals in western Europe, replacing Neanderthal populations only from about 35,000 years ago. Yet the new communities developed remarkable levels of cultural expression. In southwest France, the Pyrenees and northern Spain, hundreds of caves decorated with paintings of symbols and animals have been discovered, evidence of a rich cultural tradition.

By 12,000 years ago, the last Ice Age was drawing to a close. As temperatures rose, vegetation spread and animals re-colonized the cold northern wastes. With them went hunters and gatherers. By 10,000 BC in Central America and the Near East, people had begun to move beyond their existing resources and to investigate new ways of producing food and manipulating plants and animals in the first experiments in farming.

8000 TO 4000 BC

FROM HUNTING TO FARMING: THE ORIGINS OF AGRICULTURE

The transition from hunting and gathering to agriculture irreversibly changed human society, but it involved the domestication (selective cropping and planting, or herding and rearing) of relatively few plants and animals and occurred independently in a very few areas. The earliest evidence of agriculture comes from the Levant 10,000 years ago, from where it spread to Europe, northern Africa and central Asia.

Ten thousand years ago, at the end of the last Ice Age, the human population numbered only a few millions and all their food came from wild plants and animals. Then people began to domesticate some species, so that today almost the entire world population depends for food on a relatively small range of crops and domestic animals. During the 150,000 years that preceded the “agricultural revolution”, anatomically modern humans had colonized most of the the globe and had learned to survive as foragers, subsisting on a great diversity of plant and animal foods. Foragers moved seasonally in small groups to obtain their food supplies and population densities remained low for many millennia.

FORAGING TO FARMING

By 8000 BC, some groups of foragers had settled down and occupied favourable sites year-round. Their populations increased, as restraints on fertility imposed by the seasonally mobile way of life were relaxed, and they ranged less far for their food. This profound change in human behaviour led to the beginnings of agriculture, enabling more people to be supported on a given area of land—although at the cost of the greater effort needed to cultivate crops and raise domestic animals. The effects of settling down, population increase, and growing dependence on agriculture led to increases in the number and size of settlements, to the development of more complex, less egalitarian societies, and, eventually, to urban life and civilization.

The earliest evidence of agriculture consists of the remains of wild species that have been altered in their morphology or behaviour by human intervention. Foremost among the crops are the cereals and pulses (peas, beans and other herbaceous legumes), the seeds of which provide carbohydrate and some protein and are easily stored. They sustained early civilizations and are still staples today. They were domesticated from wild grasses in subtropical regions, for example wheat, barley, lentil, pea and chickpea in southwestern Asia; rice, soya and mung bean in southern and eastern Asia; sorghum, other millets and cowpea in tropical Africa; and maize and the common bean in Mexico. Root crops have also become staples in many areas, such as the potato, which was domesticated in the Andes and is now a major crop of temperate areas, and manioc (cassava), yams, taro and sweet potato, all of which were native to the tropics.

DOMESTICATION OF ANIMALS

Whereas cereals and root crops were brought into cultivation and domesticated in all the habitable continents except Australia (where agriculture was introduced by European settlers in the 18th century AD), animals were domesticated in relatively few areas, principally in western Asia, where there is evidence for the early domestication of sheep, goats, pigs and cattle, followed later by asses, horses and camels. Some forms of cattle and pigs, as well as chickens, were domesticated in southern and eastern Asia, and cattle and pigs may also have been domesticated independently in Europe. Very few animals were domesticated in the Americas—turkey in North America and llama, alpaca and guinea pig in South America—and none in tropical Africa or Australia.

THE SPREAD OF FARMING

The earliest known transition to agriculture took place in the “Fertile Crescent” of southwestern Asia during the Neolithic period starting about 8000 BC. Sites in the Levant have yielded charred seeds and chaff of barley, wheat and various pulses, as well as the bones of domestic goats and sheep. Grain cultivation began here about 1000 years before goat and sheep pastoralism. Dependence on agriculture increased very gradually, paralleled by the spread of village settlement, the development of techniques of irrigation and terracing, and the cultivation of fruits. By the end of the Neolithic in southwestern Asia, about 6000 years ago, agriculture had spread west and east into Europe, northern Africa and central and southern Asia.

Agriculture began independently in China between 7000 and 6000 BC, in the Americas by about 3000 BC and in tropical Africa by about 2000 BC. By the time of the 16th century AD European expansion in the agricultural and pastoral economies occupied most of Eurasia, Africa and Central and South America.

10,000 TO 4000 BC

BEFORE THE FIRST CITIES: SOUTHWEST ASIA

The period 10,000 to 4000 BC witnessed three critical developments: the origins of settled life; the first farming; and the first cities. The origin of agriculture is often referred to as the “Neolithic revolution”, but archaeology reveals only gradual changes in techniques of food acquisition over thousands of years, which by 8000 BC led to villages dependent on food production.

The earliest changes visible in the archaeological record relate not to food production but to social relations, indicated not only in the tendency to reside in one location over longer periods and in the investment of labour in more substantial and more permanent structures, but also in the growth of ritual, an important factor in social cohesion. Indeed it is possible that this “symbolic revolution” was of greater immediate significance than the economic changes we associate with the origins of agriculture.

Lakeshore and riverine sites were important for their rich and varied resources, while the utilitarian date palm flourished in marsh areas in southern Mesopotamia, rich also in fish and waterfowl. The earliest permanent settlements tend to be found at the junctions of discrete environmental zones, with greater access to a variety of resources (for example Abu Hureyra on the boundary of the dry steppe and the Euphrates flood plain, and Ain Mallaha in the Jordan valley). The importance of ritual house fittings and skull cults, perhaps suggestive of the increasing importance of the family and property, is attested at some of the earliest sites (Qermez Dere), while 9th-millennium villages in Anatolia, with early evidence for the cultivation of cereals, contain impressive ritual buildings (Çayönü, Nevali Çori). The carving of stone (Göbekli Tepe, Jerf al Ahmar, Nemrik) and the working of copper (Çayönü) are found well before the appearance of true farming villages. The early use of clay for containers is attested at Mureybet on the Euphrates (9000 BC) and at Ganj Dareh in the Zagros; white lime plaster vessels are characteristic of the latest pre-pottery Neolithic phases, especially at sites in the Levant and Anatolia.

THE DEVELOPMENT OF VILLAGES

Among the best-known pre-pottery Neolithic sites is Jericho, in the 9th millennium BC already a settlement of some 1.5ha (4 acres) with, uniquely, a rock-cut ditch and stone wall with a huge circular tower ascended by means of an internal circular stair. A millennium later Basta and Ain Ghazal in Jordan are farming settlements of over 9.5ha (24 acres). Human skulls on which faces had been realistically modelled were kept by the inhabitants of these sites, while at Ain Ghazal deposits of cultic statues have been recovered.

In the 7th and 6th millennia BC, developed Neolithic villages appear over much of the landscape. They are characterized by economies dependent on domesticated plants and animals, and on sophisticated technological developments (for example an “industrial” area of two-stage pottery kilns, and the presence of lead and copper at Yarim Tepe around 6000 BC). Well-fired painted pottery characterizes these villages, which are often classified by their ceramic styles. One of the most spectacular early pottery sites is Çatalhöyük, 13ha (32 acres) in area, with extensive evidence for wealth in the form of valuable commodities such as obsidian and semi-precious stones. The house fittings bear elaborate ornaments including wall paintings and the plastered skulls of wild cattle.

TRADE AND TEMPLES

An important development attested in the Neolithic villages of north Mesopotamia and Syria is the earliest record-keeping, effected by the use of combinations of small clay tokens and the stamping of distinctive clay or stone seals onto clay lids and other fastenings (most importantly at Sabi Abyad in the Samarran period and slightly later at Arpachiyah). Such simple methods of validating social contracts and other transactions formed the basis of later literate urban recording systems.

Mesopotamia had no metals or semi-precious stones, and by the 5th millennium BC demand for such luxury goods led to the establishment of small colonies in Anatolia, even as far as the Malatya plain (Değirmentepe) and the sea-borne exploitation of the resources of the Persian Gulf (Dosariyah, Abu Khamis), even as far as the Musandam peninsula. The first temples were built at this time in southern Mesopotamia, precursors of the institutions around which the earliest urban states were organized. There was a temple on the same site at Eridu for 3500 years, striking evidence of the continuity of tradition which was one remarkable feature of the world’s earliest city-states.

Despite their precocious development, sites like Jericho and Çatalhöyük did not form the focus of more complex polities. By 4000 BC the foundations of literate, urban civilization had been laid in Mesopotamia, where it was the organizational and economic potential of the highly productive irrigation economy in the south and the powerful, strategic positions of sites like Nineveh in the north, controlling access to areas rich in raw materials, that saw the growth of the world’s first complex states.

7000 TO 2000 BC

EARLY EUROPE: THE COLONIZATION OF A CONTINENT

Farming first spread from the Near East to southeast Europe c. 7000 BC and then along the Mediterranean coast and across central Europe, reaching the Low Countries by 5000 BC. After a brief pause it spread to Britain and northern continental Europe by 4000 BC. It was only c. 2000 BC that farming reached the more northerly parts of European Russia and the Baltic.

The earliest farming villages in Europe, dating to immediately after 7000 BC, were on the western side of the Aegean (eg Argissa) and on Crete (eg Knossos), but by 5500 BC such villages were distributed widely across the Balkans. They consisted of clusters of mudbrick buildings, each with a similar layout of hearth and cooking and sleeping areas. Their economy was based on keeping sheep and cultivating wheat and legumes. Such villages were situated in areas of good soil with a plentiful water supply and were often occupied for hundreds of years.

AGRICULTURAL VILLAGES

Villages of this kind spread inland as far as Hungary but from here northwards a new pattern developed. The mudbrick dwellings were replaced by wooden long-houses whose remains did not build up into settlement mounds. Agricultural settlement spread in a broad band from northeast France to southwest Russia on soils produced by the weathering of loess—a highly fertile windblown dust laid down during the Ice Age. Over this area the characteristic pottery was decorated with incised lines in spiral or meandering bands, a uniformity which reflects the rapid spread of settlement between 5500 and 5000 BC. Cattle were more important than sheep in the forested interior of Europe but wheat continued as the main cereal crop. The settlers did not clear wide areas of land but practised intensive horticulture in the valleys around their settlements.

At the same time as it was spreading into continental Europe, aspects of an agricultural way of life were also spreading westwards along the northern shore of the Mediterranean, reaching Spain by around 5500 BC; in this zone environmental conditions were much closer to those where agriculture started and fewer adjustments had to be made.

Alongside the early agricultural communities, small groups of foragers pursued their way of life in areas untouched by the new economy. Hunting populations were rather sparse in the areas first selected by agriculturists, and the rapidity with which farming spread across the loess lands may in part reflect a lack of local competition, but elsewhere foragers were more numerous. They were especially well-established in the lake-strewn landscapes left by the retreating ice sheets around the Alps and on the northern edge of the North European Plain.

There has been much debate about whether the spread of agriculture was due to the expansion of colonizing populations from the southeast or to the adoption of the new way of life by existing foragers. Current evidence from archaeology and the analysis of the DNA of modern populations suggests that there was a colonizing element, probably associated with the expansion through the Balkans and the loess lands of central Europe, but that in most of Europe the dominant process was the adoption of agriculture and its material attributes by existing populations, perhaps in part because of the prestige of the new way of life.

MEGALITHIC EUROPE

In much of western Europe, farming was first adopted around 4000 BC and the clearance of land in rocky terrain provided the opportunity to build large stone (megalithic) monuments as burial places and mortuary shrines for the scattered hamlets of early farmers. Some of the earliest megalithic tombs were built in Brittany and Portugal around 4500 BC, but particularly elaborate forms were made in Ireland and Spain up to 2000 years later. Alongside the tombs, other kinds of megalithic monuments were constructed in some regions, such as the stone circles of the British Isles.

From 4500 to 2500 BC, important developments occurred which were to change the established pattern of life. Early metallurgy of copper and gold developed in the Balkans from 4500 BC, although whether this was an independent invention or came from the Near East is still in dispute. Fine examples of the products come from the rich Copper Age cemetery of Varna on the Black Sea coast.

From around 3500 BC there is evidence of contact between eastern Europe and the steppe zone north of the Black Sea; some link this to the spread of Indo-European languages to Europe. The time around 3500 BC also saw the rapid spread across Europe of wheeled vehicles and the plough, both associated with the first large-scale use of draught animals. These slowly changed the nature of agricultural production. Widespread clearance of forests took place and flint mines produced stone for large quantities of axes. It was only after 2000 BC that stone axes were superseded by metal ones in western Europe.
