Intensive survey and three sample sections at Jebel Gharbi in north-west Libya offer a new dated sequence of the environment, and the human presence within it, from the Middle Stone Age to the early Holocene. Hunter-gatherers were continuously active, including during the hitherto elusive Later Stone Age.

During the last two decades the Broad Spectrum Revolution, a proposed food-getting adaptation of the terminal Pleistocene, has been generally accepted as an explanatory factor in the accomplishment of food production in Early Holocene Southwest Asia. A survey of faunal and other prehistoric data from the Levant is employed here to argue that wide-ranging exploitation of plants and animals had been persistent in the region from at least the Middle Palaeolithic, and that the issue of taxonomic diversity is unrelated to trends toward food production at the end of the Pleistocene.

The authors present a new type of communal and monumental structure from the earliest Neolithic in western Asia. A complement to the decorated stone pillars erected at Göbekli Tepe in the north, ‘Wadi Faynan 16 Structure O75’ in the southern Levant is a ritualised gathering place of a different kind. It serves to define wider western Asia as an arena of social experiment in the tenth millennium BC, one in which community seems to take precedence over economy.

The authors present new research on the Chifeng area of north-eastern China where they have been studying the remains of a society of the second millennium BC. This northern region, which saw the introduction of agriculture at the same time as the Yellow River basin experienced a brief and intensive period of fortification in the Late Neolithic/Early Bronze Age: natural ridges above the valleys were ringed with double stone walls and semicircular towers enclosing clusters of round houses with yards. Using large-scale survey and analysis of the structures at the key site of Sanzuodian, they place this phenomenon in its cultural and social context.

Satellite photographs, such as the CORONA series, are proving valuable instruments of archaeological reconnaissance, especially for landscapes that are relatively unknown or unprotected. Moreover, satellite imagery can be used for detailed mapping of remote areas, so that a topographic map or Digital Elevation Model can form the background for the archaeological information. However, images seen on the photographs may not be immediately recognisable as sites, and sites on the ground may escape detection from a satellite. In a current project in south Siberia the authors test the visibility of the one against the other.

The British Isles, at the northern fringes of human occupation in Pleistocene Europe, offer a collection of Upper Palaeolithic sites which cannot match the riches of the continental mainland. And many of its sites, studied in the 19th century, have been much quarried or even quarried out. New finds from Gough's Cave — one of the classic sites that was almost emptied in the work that made it classic-show, nevertheless, that important new discoveries are still being made from such deposits as remain.

As Rosenfeld & Smith report in this number of ANTIQUITY, the reconciliation of conventional chronologies for rock-art with the emergent radiocarbon-based dates is not proving an easy affair. Here are the first steps for the classic area of San hunter-gatherer art, on the South Africa/Lesotho border.

The rock art of Southeast Asia has been less thoroughly studied than that of Europe or Australia, and it has generally been considered to be more recent in origin. New dating evidence from Mainland and Island Southeast Asia, however, demonstrates that the earliest motifs (hand stencils and naturalistic animals) are of late Pleistocene age and as early as those of Europe. The similar form of the earliest painted motifs in Europe, Africa and Southeast Asia suggests that they are the product of a shared underlying behaviour, but the difference in context (rockshelters) indicates that experiences in deep caves cannot have been their inspiration.

Lands in south-central Chile, long thought to have been marginal until the Spanish conquest, are here shown to have been developing complex societies between at least AD 1000 and 1500. Part of the motor was provided by coastland cultivation on raised platforms, here identified and surveyed for the first time. The authors date the field systems and suggest that they were introduced by farmers from the north seeking wetlands in the face of increasing aridity in the central Andes and southern Amazon.

Recent archaeological and botanical studies of a number of major food plants throughout the world have clearly shown that thle initial domestication of each of them was a slow and laborious process, carried out by generations of experimentalists familiar with the total ecosystem of which the plant was a part (Darlington, 1963; Harris, 1967, 1969; Ucko and Dimbleby 1969b). Therefore, any pronouncement about the who, where, how, and when of the domestication of a food plant must be based not on general preconceptions but on local facts.

The genetic history of wheat is the story of the world's temperate staple food. Arcahaeologically, charred grains are the common way wheat is preserved. Study of burnt spelt wheat from the British Iron Age shows DNA is present, and begins to shows the wheat's character.

Every age has the Stonehenge it deserves-or desires. I lectured on this subject long ago. It always provoked cries of delight from a general audience when I contrasted pictures of the wildly jagged stones seen by romantic eyes with others showing the smooth stones and regular form of the Roman temple of the Tuscan order apparent to the classical vision. I ended my lecture with Stonehenge as it appeared to our scientific age-but I did not at that time dream that our greatest prehistoric monument would actually be taken over by astronomers and recognized as a celestial observatory and calculating machine.

The authors report on investigations at quarrying sites on Mount Pua, Israel. they suggest that the area shows a degree of industrial organization from the late Lower Palaeolithic with a resultant impact on the landscape.

Western Arnhem Land is a small area (by Australian standards) on the north coast where remarkable sequences of sediment illuminate its complex landscape history. Matching the enviromental succession is an archaeological sequence with lithic sites running back into the Pleistocene. The famous richness of the region's rock-art also documents the human presence, again over a great time-depth, and gives a direct report of how ancient Arnhem Landers depicted themselves. By ‘bridging’ between these three themes, a rare and perhaps unique synthesis can be built.

Pecked figures – seeming to depict humans, animals, objects and ‘abstract’ shapes - are an important and recalcitrant aspect to the archaeology of the desert USA, in the Great Basin and the Southwest. Where they are covered by desert varnish, they provide an opportunity for an absolute dating by cation-ratio method. Here - as they did not for a similar study in South Australia reported in an earlier Antiquity - the cation-ratio dates do seem to run alongside the chronological pattern inferred by conventional means.

The article by Bahn and Pettitt (above) carries the suggestion that the diverse dates obtained for Candamo in some way throw doubt on those for Chauvet and by implication on the performance of the Laboratoire des Sciences du Climat et de l'Environnement (LSCE) at Yvette-sur-Gif (Gif). The authors respond. Readers might also like to note the article by Marian Scott and colleagues which follows.

While palaeobotanical remains provide clear evidence for the exploitation of the date at various locations in Egypt and Nubia, it is the detection amongst lipid residues in closed form vessels of fatty acid distributions dominated by diagnostic short-chain fatty acids, i.e. C12:0 and C14:0′ that provides the first direct evidence for the processing of palm fruit in pottery vessels.
