Playful spaces? a social geography of children's play in Livingston,Scotland

It is often assumed that ‘play’ is an unproblematic category of children's activity, but consideration should be given to whether it is really an adult construction full of questionable assumptions about enjoyable activities free of stress for the children concerned. This paper offers some empirical materials to begin such a deconstruction of ‘play’ through an inquiry into the social geography of children's play in a Scottish new town. By retrieving what children think about their own play, what it entails and the spaces, places, social encounters and social variations central to it, it is possible to sketch out a social geography of children's play that, if not entirely unexpected, does suggest the ‘nature’ of play to be less certain than might commonly be supposed.     

Disappearing from the World: An Archaeological Perspective on Neanderthal Extinction

This paper is concerned with the statistical precision of radiocarbon dating at the earlier range of its efficacy – the period into which falls the extinction of the Neanderthals. The many potential problems affecting accuracy of this technique are discussed as a caveat as to what one might expect of future research and development in this field. The main aim of the paper, however, is to examine exactly what our chronological precision is in the period 30–40 ka BP, i.e. at around five to seven half lives of radiocarbon. If mathematical models of Neanderthal extinction are correct, the whole process could have occurred within the error of one radiocarbon date at two standard deviations, which does not bode well for understanding what must have been a complex set of processes. The assumptions made by palaeoanthropologists working with this problem are discussed, particularly in relation to how dates are actually used, and how sedimentology affects chronology. These problems aside, a coarse and necessarily provisional attempt to interpret the existing archaeological database is made, with the assumption that Late Middle Palaeolithic and 'transitional' industries are proxy indicators of Neanderthal presence in a region. From this, it is suggested that the processes of Neanderthal extinction began by c. 40 ka BP in the Balkans and Central Europe, radiating out from there, leaving Neanderthals on the periphery of their old distribution (southern Iberia, southern Italy, Crimea, Siberia, and one might predict the United Kingdom) as late as c. 29 ka BP. The processes differ in signature (and therefore by extension nature and quite possibly cause) region to region, and because of this, the role of anatomically modern humans in the extinction of Neanderthals is questioned.     

Mitochondrial DNA haplotypes of Devensian hyaenas from Creswell Crags,England

Spotted hyaena (Crocuta crocuta) remains have been recovered from British Middle and Upper Pleistocene sites at intervals within the period 700–730 ka BP. Morphological studies have suggested that hyaenas of the Last Interglacial sensu stricto (Ipswichian: Marine Isotope Stage [MIS] 5e, 130–115 ka BP) and Last Glacial (Devensian: MIS 3, 61–24 ka BP) were two distinct populations, the Ipswichian hyaenas becoming extinct in Britain during MIS 5 and the Devensian ones arriving via a subsequent migration from continental Europe. However, the apparent presence of hyaenas in later MIS 5 deposits has led to the alternative suggestion that there was a southern relict population from which the Devensian hyaenas originated. We obtained ancient DNA (aDNA) sequences from four Devensian hyaena specimens from Creswell Crags, Derbyshire, dated to around 45 ka ¹⁴C BP. Each of these four specimens belonged to the mitochondrial DNA (mtDNA) clade A. This clade is not thought to have been present in Europe until ~360 ka BP, after the initial arrival of hyaenas in Britain. The DNA results, therefore, suggest that there were at least two waves of hyaena dispersals into Britain. The results are consistent with the repeated dispersals into Britain of another Pleistocene social carnivore, Homo sapiens.     

Oldowan reduction sequences: methodological considerations

Transport of resources is a major feature of Oldowan hominin technological adaptations. Comparisons between different Oldowan localities often employ measures of transport that are based on artefact attributes as proxies for the intensity of raw material utilization. The Technological Flake Category system [Toth, N., 1985. Oldowan reassessed: a close look at early stone artifacts, Journal of Archaeological Science 12, pp. 101–120] has been used extensively to infer the relative intensity of lithic reduction within Oldowan assemblages. Here we use a large experimental sample to test the relationship between a flake's stage in a reduction sequence and various quantitative attributes. We demonstrate how many previously described attributes are affected by initial core size. We then develop a multiple linear regression model that incorporates several variables to predict the placement of a flake within a generalized reduction sequence. The model is then applied to Oldowan assemblages in the Koobi Fora Formation which explores the strengths and weaknesses of different methods of investigating reduction intensity on an assemblage level.
