The ecological tolerances of Neandertals, their ability to subsist in the dense forests of full interglacials, and their capacity to colonize northern latitudes are the subject of ongoing debate. The site of Hollerup (northern Denmark) lies at the northern extreme of the Neandertal range. Dated by various techniques to the Eemian interglacial (MIS 5e), this site has yielded the remains of several purportedly butchered fallow deer (Dama dama). Taphonomic reanalysis of the remains from Hollerup and a handful of other Eemian-aged fallow deer skeletons cast doubt on the interpretation that they were humanly modified. We place this revised conclusion into the wider context of human settlement of southern Scandinavia during the Eemian. Other claims of Neandertal presence in the region rest on candidate Middle Paleolithic artifacts, all of which derive from surface contexts. With the fallow deer material removed as a secure indicator of Neandertal settlement of Denmark during the last interglacial, this lithic material must be viewed with renewed skepticism. While ecological and/or topographic factors may have played an important role in preventing Neandertals from penetrating into peninsular Scandinavia, we caution that geological, taphonomic, research-historical, and demographic factors may have significantly distorted our picture of their occupation in this region.  相似文献

Sustainable mobility has been an important concern in urban planning and development in Oslo Metropolitan Area since the 1990s. The period has been characterized by concentrated and compact urban development, especially within the municipality of Oslo. This has contributed to a reduction in growth in car traffic. Analyses of selected land use and transport plans and policy documents, professional journal articles and interviews with key actors show that there has been a high degree of consensus about this spatial development strategy. Considerable investments have been made in public transport as well as in road development; the former based on broad consensus. Road capacity increases have been contested among professionals but widely supported by politicians.  相似文献
