A group of Linearbandkeramik people at Talheim, Germany were previously found to have died at the same time, probably in a massacre, and the authors were able to ask some searching questions of their skeletons. The isotope signatures of strontium, oxygen and carbon, which gave information on diet and childhood region, showed up three groups which correlated with hereditary traits (derived previously from the analysis of the teeth). In the local group, there were many local children but no adult women, suggesting they had been selectively taken alive at the time of the massacre. Another group, with isotope signatures derived from upland areas, includes two men who may have been closely related. A third group has a composition suggestive of a nuclear family. The variations of one type of isotope signature with another suggested subtle interpretations, such as transhumance, and a probable labour division in the community between stockholders and cultivators. Here we see the ever-growing potential of these new methods for writing the ‘biographies’ of prehistoric skeletons.

Stable isotope analysis is a new, not-so-secret weapon which promises much in mapping population movement on a regional and local scale. Lining up these movements with certain economic strategies, such as farming or foraging, with social strategies such as exogamy or with ethnicity and ranking constitutes forgivable temptation. Here our astute authors urge caution. Taking the Mesolithic-Neolithic transition in south-west Germany as their example, they show that caution does not inhibit interpretation, but opens the door to more subtle, more human possibilities.
