We studied 36 dogs (Canis familiaris) from the Can Roqueta site in the Catalan pre-littoral depression (Barcelona), dated between the Late Bronze Age and the First Iron Age (1300 and 550 cal BC). We used a sample of 27 specimens to analyse the evolution of the dogs’ diet based on the carbon δ¹³C and nitrogen δ¹⁵N isotope composition. The results show a marked human influence in that these natural carnivores display a highly plant-based diet. The offset between canids and herbivorous ungulates does not reach the minimum established for a trophic level, which implies an input of C₃ and C₄ (millet) cultivated plants. Moreover, the homogeneity in the values indicates that humans prepared their dogs’ food.

The colonisation of eastern parts of the Pacific Islands was the last phase in the preindustrial expansion of the human species. Given the scale and challenges of the endeavour it is unsurprising that scholars have long been interested in understanding the conditions that drove and supported the exploration and settlement of this vast region. There has been speculation as to the influence of demographic factors, either as drivers or in some way regulating the rate and success of human expansion, but testing this has proven challenging. This study evaluates two hypotheses of population dynamics: the adaptation/resilience hypothesis, which proposes that populations respond to localised environmental conditions and changes in subsistence strategy, technology, differences in pathogen loads, and other events that occur at different times in different places; and the temporal hypothesis, which proposes that populations respond to major events such as climate change that occur in a region at an absolute point in, or over an absolute period of, time (noting that the two hypotheses are not mutually exclusive). Applying new methods for estimating the rate of natural population increase from human skeletal remains, this study utilised 23 samples to evaluate trends in population increase following the human expansion into the region. The results indicate a trend in population growth following colonisation, with initially high population growth, followed by a significant decrease and subsequently an increase in growth rates. The lack of a temporal trend may represent a high degree of heterogeneity in the impacts of climate change on individual archipelagos and islands.

In place of the traditional view that raids and invasion from the north introduced new weapons and chariots to the Shang (c. 1200 BC), we argue that archaeological evidence illustrates the presence of several regional groups at or near the late Shang centre, Anyang. Here we review burial practices at Anyang dating to the late second millennium BC, and describe a substantial group of prone burials that reflect a ritual practice contrasting with that of the predominant Shang elite. Such burials occur at all social levels, from victims of sacrifice to death attendants, and include members of lower and higher elites. Particularly conspicuous are chariot drivers in some chariot pits. An elite-level link with chariots is confirmed by the burial of a military leader in tomb M54 at Huayuanzhuang at Anyang, with tools that match exactly those of chariot drivers. Given that prone burial is known to the north, in the Mongolian region that provided chariots and horses to the Shang, a route can be traced eastwards and southwards, down the Yellow River, and then through mountain basins to Anyang. Our inference is that a group originally from outside the Central Plains can be identified in these distinctive burials. This marks a first step towards understanding the heterogeneity in the central population of the late Shang.
