Human migration tends to involve more than the odd suitcase or two - we often carry other organisms on our travels, some are deliberately transported, others move by accident. This volume of 12 papers offers a zooarchaeological approach to questions surrounding the nature and extent of human colonisation and migration, and the adaptation of humans to new and sometimes extreme or challenging environments. The volume is divided into two parts: Part 1 takes up the theme of Human and Animal Migration and Colonisation. Contributors consider the relationship between human movements and the movements of animals and animal products; case studies look at Neolithic population movements in Oceania, the Norse colonisation of Greenland, and the European settlement of Virginia. Part 2 focuses on the topic of Behavioural Variability in the So-Called Marginal Areas. Contributors offer various interpretations of the concept of 'marginality', from climatic extremes of the Arctic cold, and the heat and aridity of western North America, to the geographical remoteness of Patagonia, and the cultural circumstances surrounding the beginnings of transhumant pastoralism in prehistoric southeastern Europe.
