Ever since the publication of the first of more than 50 internally consistent radiocarbon dates from Meadowcroft Rockshelter (36 WH297), controversy has been generated by frequent assertions that the dates older than 11,000 B.C. have suffered particulate or nonparticulate contamination. Data bearing on these assertions are assessed in the light of accelerator mass spectroscopy (AMS) dates provided by Oxford University. The weight of all data taken together suggests that this site still represents the best-dated evidence for the presence of human beings south of the glacial front in the Americas. That evidence indicates that Native Americans were present in southwestern Pennsylvania by 14,000–14,500 years ago.

Alaska is commonly viewed as a gateway between the Old and New Worlds, and as such, figures prominently in most models of the peopling of the New World. With a growing number of archaeological sites dating to the terminal Pleistocene, Alaska might be expected to provide direct evidence bearing on the colonization of the Americas. Based on 27 site components with 114 radiocarbon dates, this paper discusses the archaeological record of late Pleistocene Alaska, organized around the characteristics and chronology of three complexes: the microblade-bearing Denali complex, the Nenana complex, and the Mesa complex. This paper shows that the archaeological record of late Pleistocene Alaska is quite diverse, and not lacking in controversy and conflicting interpretations. In addition, this period of archaeological diversity coincides with the Younger Dryas climatic event. However, none of the reliably dated sites is older than the earliest evidence of human occupation further south in the Americas. Despite this, evidence from DNA studies points strongly to a north-central Asian homeland for Native Americans, upholding Alaska as the point of entry into the New World. Suggestions are offered, then, as to why the Alaskan record remains silent about the initial peopling of the New World.

AbstractThis paper aims to define the first chrono-cultural framework on the domestication and early diffusion of the opium poppy using small-sized botanical remains from archaeological sites, opening the way to directly date minute short-lived botanical samples. We produced the initial set of radiocarbon dates directly from the opium poppy remains of eleven Neolithic sites (5900–3500 cal BCE) in the central and western Mediterranean, northwestern temperate Europe, and the western Alps. When possible, we also dated the macrobotanical remains originating from the same sediment sample. In total, 22 samples were taken into account, including 12 dates directly obtained from opium poppy remains. The radiocarbon chronology ranges from 5622 to 4050 cal BCE. The results show that opium poppy is present from at least the middle of the sixth millennium in the Mediterranean, where it possibly grew naturally and was cultivated by pioneer Neolithic communities. Its dispersal outside of its native area was early, being found west of the Rhine in 5300–5200 cal BCE. It was introduced to the western Alps around 5000–4800 cal BCE, becoming widespread from the second half of the fifth millennium. This research evidences different rhythms in the introduction of opium poppy in western Europe.

Throughout time, human beings have been fascinated with music. Research in music psychology has revealed how musicians acquire the ability to convey emotional intentions as sounded music, how listeners perceive it as feelings and moods, and how this powerful process relates to social and cultural dynamics. Of course, people who identify as musicians have special interest in these matters. In recent years, a psychological perspective has gained increasing acceptance in the education provided to musicians: teachers, performers, and “creatives” alike. The first edition of Psychology for Musicians: Understanding and Acquiring the Skills (2007, Oxford University Press) was a well-cited volume over the years. This new edition draws on the greater insights provided by recent research in music psychology. It combines academic rigor with accessibility to offer readers research-supported ideas that they can readily apply in their musical activities.

Two well-known archaeological sites, the peat bogs of Shigir and Gorbunovo (Middle Urals, Russia), have been radiocarbon dated (61 conventional and accelerator mass spectrometry [AMS] dates from various natural and artifact samples). For the first time, a detailed chronology of Early to Late Mesolithic and Early Neolithic occupation for this region has been obtained, and a paleoenvironmental history reconstructed. Based on these results, we propose that the Mesolithic settlement of the Middle Urals region started in the early Holocene, at the same time as in central and eastern Europe.

We investigated chronological questions of five Late Neolithic settlements in the Hungarian Tisza-Maros region. Fifty new radiocarbon dates provide an internal chronology for the developmental phases of the tell settlements, and place them into the wider framework of the southeastern European Neolithic. An example is presented of how a unique type of stratigraphic excavation helps the interpretation of radiocarbon data, which are in contradiction with the stratigraphic position of the samples.

Isotopic analysis of dog (Canis lupus familiaris) bone recovered from archaeological sites as proxies for human bone is becoming common in North America. Chronological placement of the dogs is often determined through radiocarbon dating of dog bone. The Great Lakes, their tributaries, and nearby lakes and streams were important fisheries for Native Americans prior to and after sustained European presence in the region. Carbon entering the food web in freshwater systems is often not in full isotopic equilibrium with the atmosphere, giving rise to spuriously old radiocarbon ages in fish, other aquatic organisms, and their consumers. These freshwater reservoir offsets (FROs) have been noted on human and dog bone in several areas of the world. Here we report the results of multi-tracer Bayesian dietary modeling using δ15N and δ13C values on dog bone collagen from mid-fifteenth to mid-sixteenth-century Iroquoian village sites at the headwaters of the St. Lawrence River, New York, USA. Results indicate that fish was an important component of dog diets. A comparison of radiocarbon dates on dog bone with dates on deer bone or maize from the same sites indicate FROs ranging from 97 ± 24 to 220 ± 39 14Cyr with a weighted mean of 132 ± 8 14Cyr. These results suggest that dog bone should not be used for radiocarbon dating in the absence of modeling to determine fish consumption and that previously reported radiocarbon dates on human bone from the larger region are likely to have FROs given the known importance of fish in regional human diets.

Abstract Aim of this paper is to support the view that all human practical identities are contingent by arguing against the view that there is at least one necessary practical identity shared by all human beings, namely Humanity. The view that Humanity is a necessary practical identity is explicitly defended by Christine M. Korsgaard (Korsgaard, C. M. 1996. The Sources of Normativity, edited by O. O’Neill. Cambridge: Cambridge University Press; Korsgaard, C. M. 2009. Self-Constitution: Agency, Identity, and Integrity. New York: Oxford University Press) and indirectly by Marya Schechtman (Schechtman, M. 2014. Staying Alive: Personal Identity, Practical Concerns, and the Unity of a Life. New York: Oxford University Press). Korsgaard understands Humanity both in terms of pure self-legislation, and as deep sociality. In the first case, Humanity as self-legislation faces what I call ‘Existential dilemma’: either Humanity has specific content, typical of contingent practical identities, but stops being necessary for all human beings; or Humanity is emptied of its content and is conceived of as necessary self-legislation, but stops being a practical identity. In the second case, i.e., Humanity as deep sociality, Korsgaard confuses the necessary natural fact that human beings are social creatures, with contingent contexts of human socialization, which are the true sources of specifically human practical identities. I articulate this confusion in the guise of what I call ‘Nature/Nurture dilemma’, which also applies to the morally neutral account of human personhood advocated by Schechtman (Schechtman, M. 2014. Staying Alive: Personal Identity, Practical Concerns, and the Unity of a Life. Oxford University Press). In conclusion, I address the worry that without the necessary practical identity of Humanity we might not be able to extend our practical and moral concerns to distant fellow human beings by sketching an alternative path to extend such concerns.

ABSTRACTThis article provides a summary and in-depth analysis of all existing radiocarbon (14C) dates for the Afanasyevo Culture of the Paleometal period. The previous “long” chronology of the culture was widely criticized and contradicted many archaeological observations. The exceedingly wide ranges of the liquid scintillation counting (LSC) dates from bone samples produced in several laboratories and the systematically older ages for the wood/charcoal samples finally reveal the shortcomings of the conventional “long” chronology. From accelerator mass spectrometry (AMS), the Afanasyevo burials of the Altai are dated to the 31st–29th century BC, whereas those of the Middle Yenisei Region to the 29th–25th century BC, which confirms the relatively earlier age of the Altai monuments. The “short” chronology removes the incompatibility of deriving the Afanasyevo Culture from the Yamnaya Culture, which previously appeared “younger” than the Afanasyevo, and also contradictions with the archaeological data. It also explains the small number of sites, the small size of the cemeteries and the lack of the internal periodization. We can now clearly move, from the earlier understanding that the Afanasyevo chronology is too broad, towards a different perception. The new AMS dates only represent a “core” for the Afanasyevo chronology, which cannot be narrowed down, but could be slightly expanded over time.

This article reports on 10 new accelerator mass spectrometry (AMS) radiocarbon dates from early phases of the Early Bronze Age at the long-lived settlement of Pella (modern Tabaqat Fahl) in the north Jordan Valley. The new AMS dates fall between 3400 and 2800 cal BC, and support a recent suggestion that all Chalcolithic period occupation had ceased by 3800/3700 cal BC at the latest (Bourke et al. 2004b). Other recently published Early Bronze Age14C data strongly supports this revisionist scenario, suggesting that the earliest phase of the Early Bronze Age (EBA I) occupied much of the 4th millennium cal BC (3800/3700 to 3100/3000 cal BC). As this EB I period in the Jordan Valley is generally viewed as the key precursor phase in the development of urbanism (Joffe 1993), this revisionist chronology has potentially radical significance for understanding both the nature and speed of the move from village settlement towards a complex urban lifeway.
