Show moreWe explore if taxonomic analysis of archaeological mollusc assemblages can be used to reconstruct Late Pleistocene (MIS 5–3) coastal environments at Klasies River in South Africa. To obtain a balanced reconstruction, we analyse the large molluscs separately from the so-called incidentals, the small mollusc species. Based on modern mollusc habitat preferences and tolerances we identify four different eco-profiles to help characterise sea surface temperatures and the character of the shore: temperature profile; geographical distribution; substrate; wave interaction. We hypothesise that changes in the Klasies River mollusc community/eco-profiles can be linked to global glacial and interglacial events and we define several testable assumptions. We found that in response to global warming and cooling events, the Klasies River mollusc communities change slightly, yet significantly. Other sources of marine environmental data confirm that average sea surface temperatures gradually decreased, but probably remained within the modern southern east coast range of variation. It appears that coastal sea surface temperatures of the warm Agulhas current were not particularly depressed during the occupation sequence. The character of the coastal topography does change more apparently during the occupation sequence of the sites and with it the mollusc assemblages: from an interglacial rocky shore in the Klasies and two Mossel Bay phases to a more glacial sandy environment during the Howiesons Poort and the MSA III. In conclusion, the temperature tolerance levels of many Klasies River mollusc species are too broad to reflect small changes in sea surface temperatures. However, in conjunction with other eco-profiles and environmental proxies, such as substrate requirements and oxygen isotopes, the temperature approximations are useful, particularly when evaluating large scale sea surface temperature fluctuations. For the characterisation of the shore and substrate we found the eco-profile approach very useful. Show less

Show moreLivestock remains appear in the South African archaeological record around 2100 years ago. However, the economic importance of domestic animals in Later Stone Age subsistence is debated. This paper adopts an approach rooted in Optimal Foraging Theory to examine if the introduction of livestock is reflected in changing taxonomic diversity of faunal assemblages. Based on the analysis of a database of 300+ faunal assemblages, it is concluded that the economic importance of livestock during the final Later Stone Age of South Africa was relatively limited.

Show moreWe review indications for the behavioural complexity of foraging strategies during Marine Isotope Stage 5 (~130 – 74 ka) at Blombos Cave and Klasies River, South Africa. Although the sites were occupied by anatomically modern humans, it is debated whether they were also behaviourally modern. The exploitation of terrestrial small nocturnal browsers may be an indication for the use of complex foraging strategies such as trapping or net-hunting. Hence we analyse the terrestrial fauna of the sites in terms of represented size classes, dietary preference and activity patterns. Seasonally planned coastal visits are also considered ‘modern’ and may be recognised by the presence of large numbers of adult male seals and by shellfish only accessible at low tide. We therefore analyse the representation of marine mammals and the represented molluscs in terms of their habitat preference. Our study suggests that trapping and net-hunting were practised in Marine Isotope Stage 5. In addition, coastal visits were probably planned. Show less

Voor het notariaat zijn met name het samenvoegen van de twee huidige afzonderlijke monumentenregisters in één monumentenregister van belang, alsmede de veranderde wijze van registratie van beschermde stads- en dorpsgezichten. Daarnaast verandert de omgang met bekende en te verwachten archeologische monumenten. Gemeenten krijgen een grote bewegingsvrijheid om het archeologisch beleid op hun grondgebied vorm te geven. In verband hiermee dient de notaris zich vooral bewust te zijn van mogelijke lokale verschillen in gronduitgifte-voorwaarden.Show less

Show moreRecent studies emphasise the mosaic character of the process of neolithisation in north-western Europe. However, some overarching motives influencing the uptake of farming can be identified across regions. We model the importance of evolutionary processes underlying neolithisation. We focus on the southern part of the Low Countries, where the uptake of agriculture follows distinct trajectories in different biomes. We analyse the transition in terms of fitness benefits that foraging and agriculture bestow on the actors involved. We suggest that different substrates offer different fitness benefits with regard to the uptake of farming and that these benefits differed between the sexes, leading to differing “optimal” strategies for males and females regarding whether and how to adopt Neolithic innovations.

Show moreMiddle and Late Pleistocene bone assemblages have been analysed to infer hominin hunting competence. Interpretations in terms of competence are usually based on the species represented in bone assemblages, such as the presence or absence of large and dangerous species. However, the sophistication of hunting strategies is not the only factor that influences the exploitation of prey species. Before interpreting an assemblage in terms of hunting proficiency, more parsimonious explanations of prey choice must be eliminated. One important reason to focus on certain species is that they are more economic to exploit than others. To test whether the presence or absence of species can be explained by economic motives rather than by hunting proficiency, Optimal Foraging Theory is applied to Pleistocene bone assemblages. The motives that drive prey choice are studied by modelling the behavioural characteristics of species and scrutinizing which characteristics the exploited species had in common. Application to Middle Palaeolithic sites in the Eemian of Germany shows that large and dangerous species were exploited frequently, but that solitary species are better represented at some sites than species living in herds. In another case-study from the Middle Stone Age in South Africa, the most important characteristic of selected prey species is their size. Large and dangerous species were preferred over smaller dangerous species. The better representation of large docile species can be ascribed to “common sense” and not, as has been suggested, to a lack of hunting proficiency. Show less
