Paleoeskimo Dogs of the Eastern Arctic

ABSTRACT. Sled or pack dogs have been perceived as an integral part of traditional life in the Eastern Arctic. This perception stems from our knowledge of the lifeway of recent Thule and modern Inuit peoples, among whom dog sledding has often been an important means of transportation. In contrast, the archaeological record of preceding Paleoeskimo peoples indicates that dogs were sparse at most, and probably locally absent for substantial periods. This pattern is real, not an artifact of taphonomic biases or difficulties in distinguishing dog from wolf remains. Analysis of securely documented dog remains from Paleoeskimo sites in Greenland and Canada underscores the sporadic presence of only small numbers of dogs, at least some of which were eaten. This pattern should be expected. Dogs did not, and could not, assume a conspicuous role in North American Arctic human ecology outside the context of several key features of technology and subsistence production associated with Thule peoples

Paleoeskimo Dogs of the Eastern Arctic

Sled or pack dogs have been perceived as an integral part of traditional life in the Eastern Arctic. This perception stems from our knowledge of the lifeway of recent Thule and modern Inuit peoples, among whom dog sledding has often been an important means of transportation. In contrast, the archaeological record of preceding Paleoeskimo peoples indicates that dogs were sparse at most, and probably locally absent for substantial periods. This pattern is real, not an artifact of taphonomic biases or difficulties in distinguishing dog from wolf remains. Analysis of securely documented dog remains from Paleoeskimo sites in Greenland and Canada underscores the sporadic presence of only small numbers of dogs, at least some of which were eaten.

Cette perception vient de nos connaissances sur le mode de vie des derniers Thulés et des Inuits modernes, chez qui le traîneau à chiens a souvent représenté un mode de transport majeur. En revanche, les données archéologiques des peuples paléoesquimaux qui ont précédé Thulés et Inuits révèlent que les chiens étaient tout au plus clairsemés, et probablement absents localement pendant de longues périodes. Cette répartition est bien réelle et n'est pas le produit de distorsions taphonomiques ou de difficultés à faire la distinction entre les restes du chien et ceux du loup. L'analyse de restes canins proprement documentés trouvés sur des sites paléoesquimaux au Groenland et au Canada souligne la présence sporadique de chiens en nombre toujours restreint, dont au moins quelques-uns étaient mangés. Cette répartition n'est pas surprenante, les chiens n'assumant pas - et ne pouvant assumer - un rôle évident dans l'écologie humaine de l'Arctique nord-américain en dehors du contexte de diverses caractéristiques clés de la technologie et de la production de subsistance associées aux Thulés

Species-specific responses of Late Quaternary megafauna to climate and humans

Despite decades of research, the roles of climate and humans in driving the dramatic extinctions of large-bodied mammals during the Late Quaternary remain contentious. We use ancient DNA, species distribution models and the human fossil record to elucidate how climate and humans shaped the demographic history of woolly rhinoceros, woolly mammoth, wild horse, reindeer, bison and musk ox. We show that climate has been a major driver of population change over the past 50,000 years. However, each species responds differently to the effects of climatic shifts, habitat redistribution and human encroachment. Although climate change alone can explain the extinction of some species, such as Eurasian musk ox and woolly rhinoceros, a combination of climatic and anthropogenic effects appears to be responsible for the extinction of others, including Eurasian steppe bison and wild horse. We find no genetic signature or any distinctive range dynamics distinguishing extinct from surviving species, underscoring the challenges associated with predicting future responses of extant mammals to climate and human-mediated habitat change.This paper is in the memory of our friend and colleague Dr. Andrei Sher, who was a major contributor of this study. Dr Sher died unexpectedly, but his major contributions to the field of Quaternary science will be remembered and appreciated for many years to come.
