Ancient human DNA from southern Iberia reveals social and genomic changes during the emergence of the Bronze Age in Europe.

Given the absence of written records, the main source of information available to analyze gender inequalities in early complex societies is the human body itself. And yet, for decades, archaeologists have struggled with the sex estimation of poorly preserved human remains. Here we present an exceptional case study that shows how ground-breaking new scientific methods may address this problem. Through the analysis of sexually dimorphic amelogenin peptides in tooth enamel, we establish that the most socially prominent person of the Iberian Copper Age (c. 3200–2200 BC) was not male, as previously thought, but female. The analysis of this woman, discovered in 2008 at Valencina, Spain, reveals that she was a leading social figure at a time where no male attained a remotely comparable social position. Only other women buried a short time after in the Montelirio tholos, part of the same burial area, appear to have enjoyed a similarly high social position. Our results invite to reconsider established interpretations about the political role of women at the onset of early social complexity, and question traditionally held views of the past. Furthermore, this study anticipates the changes that newly developed scientific methods may bring to prehistoric archaeology and the study of human social evolution.

Because of its great potential to provide data on contacts and overseas trade, ivory has aroused a great deal of interest since the very start of research into Iberian late prehistory. Research recently undertaken by the German Archaeological Institute in Madrid in collaboration with a number of other institutions has provided valuable contributions to the study of ivory in the Iberian Copper Age and Early Bronze Age. One of the archaeological sites that is contributing the most data for analysing ivory from the Copper Age in southern Iberia is Valencina de la Concepción (Seville), which is currently the focus of several debates on the development of social complexity. This article contributes to this line of research by providing new, unpublished evidence and by examining the significance of ivory craftsmanship in commercial, social, and ideological terms. It also assesses in greater detail the prominent part played by luxury ivory items as an expression of social status and power.
