Thousands of artefacts are found every year by the public the world over, and many are sold or destroyed. How are we to ensure that these discoveries can take their place in archaeological research (Editorial, December 2004)? For some, legislation, state control and strong penalties are the best or only option. Here, the co-ordinator of the English Portable Antiquities Scheme makes the case for a voluntary code, led by co-operation, education and reward.

Almost a century and a half ago, Charles Darwin in The Descent of Man (1871: 141) highlighted the evolution of bipedalism as one of the key features of the human lineage, freeing the hands for carrying and for using and making tools. But how did it arise? The famous footprints from Laetoli in Tanzania show that hominin ancestors were walking upright by at least 3.65 million years ago. Recent work, however, suggests a much earlier origin for bipedalism, in a Miocene primate ancestor that was still predominantly tree-dwelling. Here Susannah Thorpe, Juliet McClymont and Robin Crompton set out the evidence for that hypothesis and reject the notion that the common ancestor of great apes and humans was a knuckle-walking terrestrial species, as are gorillas and chimpanzees today. The article is followed by a series of comments, rounded off by a reply from the authors.

The colonisation of the Pacific islands represents one of the major achievements of early human societies and has attracted much attention from archaeologists and historical linguists. Determining the pattern and chronology of colonisation remains a challenge, as new discoveries continue to push back dates of earliest settlement. The length and direction of the colonising voyages has also led to lively debate seeking to trace languages and artefactual techniques and traditions to presumed places of origin. Seafaring simulation models provide one way of resolving these controversies. One of the most remote of these island groups, the Marianas, is shown here to have been settled not from Taiwan or the Philippines, as has been argued in Antiquity by Hung et al. (2011) and Winter et al. (2012), but from New Guinea or Island Southeast Asia to the south. It represents an incredible feat of early navigation over an ocean distance of some 2000km.

Recent prehistoric and palaeoanthropological debate is focusing new interest on the peopling of the Americas — an old and difficult research-case. Proponents of new sites need to submit their putative 'new and revolutionary' discoveries to a wider judgement, mainly contra sceptics and partisans of more conservative theories. Such a review is helpful, and we are grateful to our colleagues for their considered assessment of the evidence proposed in our Brazilian research. Nevertheless their view of the Pedra Furada evidence has gaps, misunderstandings and ambiguities.

More on whether evidence of prehistoric environment on the Pacific island of Mangaia does or does not demonstrate an early human presence there.

Two fundamentals for the place of the individual in society are age and gender; well-studied cemeteries can provide an good archaeological base for their study. This examination of the Copper Age site of Tiszapolgár-Basatanya, Hungary, explores the relationship between age and gender though the course of prehistoric lives and how it might be possible to distinguish sex from gender in archaeological contexts.

A team of Elders and community officials from the island of Mua in the Torres Straits got together with archaeologists from Australia to study an episode which occurred on the island before the coming of Christianity in 1871. Oral tradition located the burial place of the father of an ancestral islander named Goba, and the investigation of a rock shelter nearby gave a dated sequence of occupation and a fresh sighting of rock paintings, all relating to the period. Each type of evidence gave context to the other, and the project offered a vivid example of how history is fashioned.

The rôle played by humans in the extinction of late Pleistocene vertebrate fauna is a controversial topic (Diamond 1989; Grayson 1989; Martin & Klein 1984), and actual archaeological data for a human factor are quite rare. Recent multidisciplinary excavations in Cyprus, however, suggest that people were at least partially responsible for the extinction of local endemics, primarily pygmy hippopotamus (Phanourios minutus).

The Iron Age in north-eastern Thailand is marked by the appearance of multivallate ‘moated sites’ some of them up to 50ha in extent. Current evidence for their date and function shows them to be contemporary with other developments – expansion into new agricultural land, increases of ranking in burial and the arrival of regional pottery industries. In interpreting the reasons for these changes, the author draws on analogies from the Bronze/Iron transition in Britain, where forts are also seen as instruments of socio-economic change.

The rock-shelter of Jinmium in the Northern Territory of Australia hit the headlines a year-and-a-half ago when TL dates suggested human occupation might date from 116,000 years ago. Such dates were much earlier than any previously obtained for Australia, and thus suggested the continent was colonized at a very early stage in human dispersal around the Pacific. However, some TL dating is notoriously difficult to interpret, and here Nigel Spooner has re-assessed one of the later dates in the Jinmium sequence. His interpretation calls into doubt some of the earlier claims.

Samples from three charcoal pictographs at Ignatievskaya Cave, in the southern Ural Mountains of Russia, have been radiocarbon dated. An advanced antiquity was expected, with some paintings thought to be more than 10,000 years old, as suggested by the imagery. One charcoal painting, for example, resembles a mammoth. The radiocarbon date of that motif, however, dates only to 7370±50 BP. If that motif actually represents a live mammoth, it places mammoth extinction in the Urals nearer to the present than is currently accepted. A charcoal pigment sample, a drawing of lines radiating from a central focus, has also been dated; its age was a few hundred years older than the ‘mammoth’: 7920±60 BP. A charcoal line has been dated with an age of 6030±110 BP. Although radiocarbon analysis was attempted on a red-pigmented painting of a woman, there was not enough organic material in the paint sample to obtain a viable date. Radiocarbon dates on pictographs in Ignatievskaya Cave obtained so far suggest that the paintings may be more recent than has been supposed.

The Pre-Pottery Neolithic A (PPNA; c. 9600–8500 cal BC) period in the Levant provides the earliest confirmed evidence for plant cultivation anywhere in the world, marking a significant escalation in the human management of plants towards fully fledged agricultural food production. Until now, the majority of PPNA sites have been documented in the Jordan Valley, the Wadi Araba and farther north along the Upper Euphrates (e.g. Mureybet, Jerf el-Ahmar, Djade). By contrast, few PPNA sites have so far been reported from the semi-arid to arid eastern part of the Levantine interior. Among these is El Aoui Safa (Coqueugniot & Anderson 1996) and sporadic flint scatters elsewhere in the Harra. Recent fieldwork in the Qa’ Shubayqa area in the Harra has produced the first evidence for a more substantial settlement site in this region.

This paper presents the recent discovery of extensive and intensive middle Bronze Age exploitation of the marshland along the northeastern bank of the River Thames and its tributaries within a wider regional context. It also develops a site location model, and explores reasons for the presence of these sites.

The site of Doel lies beside the Schelde, close to Antwerp. Excavations have uncovered the remains of two prehistoric zones, one from the Final Mesolithic and one from the Neolithic. Preliminary study suggests that current theories of the Mesolithic-Neolithic transition in northern Belgium require revision.

The island of Cyprus was a major producer of copper and stood at the heart of east Mediterranean trade networks during the Late Bronze Age. It may also have been the source of the Red Lustrous Wheelmade Ware that has been found in mortuary contexts in Egypt and the Levant, and in Hittite temple assemblages in Anatolia. Neutron Activation Analysis (NAA) has enabled the source area of this special ceramic to be located in a geologically highly localised and geochemically distinctive area of western Cyprus. This discovery offers a new perspective on the spatial organisation of Cypriot economies in the production and exchange of elite goods around the eastern Mediterranean at this time.

The author presents new radiocarbon dates for chariot burials found in the region between Europe and the Urals, showing them to belong to the twentieth-eighteenth centuries BCE. These early dates, which pre-empt the appearance of the war chariot in the Near East, are transforming the ancient history of Eurasia and the early Mediterranean civilisations, pointing to the Volga-Ural area as an important centre of innovation for early Europe.

The earthquake that struck Japan on 11 March 2011, named the Great East Japan Earthquake by the Japanese government, was one of the largest seismic events the world has seen for generations. Akira Matsui reported his experience of visiting the areas devastated by the earthquake and tsunami soon afterwards, outlining the initial assessment of damage caused to museums and cultural heritage assets, and the plans for their rescue (Kaner et a/ 2011; Matsui 201 I a). The present contribution reports how far the implementation of these plans has been successful, the prospects for the future, and situates all of this in a broader context of archaeological response to earthquakes.

The astronomical significance of Stone- henge has been the subject of intermittent debate and speculation ever since 1740, when Stukeley [I] first observed that the axis of the sarsen structure and of the Avenue pointed at least approximately to the sunrise at the summer solstice. Apart from Sir Norman Lockyer [z], however, few professional astronomers concerned themselves with this question, until the appearance in,Nature of the two articles by Gerald S. Hawkins, Professor of Astronomy at Boston University, in 1963 and 1964 [3]. The first of these claimed the discovery of a number of additional alignments of astronomical significance, marked by pairs of stones and other features of the site; and the second suggested that the Aubrey Holes had been used as a neolithic 'computer' for the prediction of movements of the moon and of eclipses. Subsequently these theories received much wider publicity, in Britain as well as in the United States, through a CBS television programme, The Mystery of Stonehenge, which provided a superb example of partiality and tendentiousness in the presentation of an academic controversy.

Professor Hawkins has now elaborated his ideas in a book whose title, Stonehenge Decoded, leaves no doubt of his confidence in the rightness of his conclusions-a confidence explicity echoed in his text. 'There can be no doubt that Stonehenge was an observatory; the impartial mathematics of probability and the celestial sphere are on my side' (p. vii). 'I think I have demonstrated beyond reasonable doubt that the monument was deliberately, accurately, skilfully oriented to the sun and the moon' (pp. 146-7). 'I think I have put forward the best theory to account for the otherwise unexplained holes' (p. 147). 'I think there is little else in these areas that can be discovered at Stonehenge'(p. 147).
