Animal Genetics and African Archaeology: Why It Matters

摘要

This article introduces the special issue of African Archaeological Review on the relevance of African livestock genetics to archaeology on the continent. It shows how modern and ancient animal genetic research in Eurasia has substantially revised archaeological scenarios for the origins and spread of food production there. It argues that, in contrast to colleagues in Europe and Asia, Africanist archaeologists have generally been slow to engage in truly collaborative research with archaeogeneticists, with some notable exceptions. It builds a case that animal introductions and domestication are as much social, cultural, and economic processes as they are ecological in nature. Through examples, it outlines some profound selective effects that animal keeping has had on humans themselves. Building on the concepts of taste and embodied practice in Stahl’s (2002) discussion of artifacts and differently scaled encounters with non-local commerce, it develops suggestions for archaeologically studying genetically distinctive domestic animals as part of local and long-distance economic systems. Finally, it comments on the issue’s review articles and offers suggestions for ways to encourage stronger collaboration between archaeologists and genetic researchers.
