Human bioarchaeology: Group identity and individual life histories – Introduction

The approach of individual life histories has been facilitated by a rapid growth in the area of bioand archaeological sciences, and in human osteology. Concurrent improvements to radiocarbon dating and focus on high resolution paleoenvironmental reconstructions have moved the new research to the annual or decadal scale of analysis. Together, this new approach allows us: (1) to reconstruct long segments of individual life histories from birth to death; (2) to assess variation in prehistoric human behaviour; and (3) to place this behaviour in the context of dynamic interactions with the natural environment. The emphasis on individuals rather than groups or cultures feeds naturally into the modern scientific-evolutionary archaeology, a school of thought which focuses on mechanisms generating human cultural diversity. While it is the populations that evolve, it is the variation generated at the individual level that is necessary to set this process in motion. To an evolutionary archaeologist and anthropologist it is the behavioural variability that is of primary research interest. Hence the paramount importance of documenting and understanding what people do on a daily basis and how they differ from each other in their needs, preferences, choices, decisions, and strategies developed and employed to satisfy them. 2012 Elsevier Inc.
