EXPLORING MOBILITY PATTERNS AND BIOLOGICAL AFFINITIES IN THE SOUTHERN AEGEAN: FIRST INSIGHTS FROM EARLY BRONZE AGE EASTERN CRETE by Sevi Triantaphyllou*, Efthymia Nikita and Thomas Kador *Department of History and Archaeology, Aristotle University of Thessaloniki Fitch Laboratory, British School at Athens Department of Archaeology and Anthropology, University of Bristol This paper presents the results of a pilot project which combines, for the first time, biodistance and strontium isotope analyses in the study of human skeletal remains from Early Bronze Age Crete (third millennium bc). Information from these analyses offers, in a direct way, insights into the biological distance, and consequently the gene flow and mobility patterns, among human populations in eastern Crete. The results are synthesised with the evidence of funerary practices in order to explore the nature of interaction among communities in eastern Crete. The biodistance analysis supports a strong genetic affinity between the populations represented at the two Kephala Petras skeletal assemblages, while the results of the available strontium isotope analysis favour their local origin; thus the combined results suggest the lack of significant population influx. The biological distance of the two chronologically contemporary populations at Livari-Skiadi, also manifesting completely different patterns of mortuary disposal, is of particular interest since it contrasts with the Petras situation and raises issues of intra-community distinctions, cultural and biological. INTRODUCTION The mobility of materials, ideas and technological knowledge has recently attracted the attention of historical and archaeological research. Contrary to the culturalhistorical approach to archaeology, where culturalentities are assumed to correspond to particular groups of people (Trigger ), recent studies of identity trace the movement of material and humans in order to offer interpretations of the scale and nature of such interactions (Zakrzewski ). Powerful tools, such as biodistance studies, combined with biomolecular and chemical analyses, can provide new insights into the behaviour of past populations (e.g. Gilbert et al. ; Brown and Brown ; Pinhasi and Stock ; Shapiro and Hofreiter ). Skeletal morphology is, in part, genetically determined and it is well established that analyses of metric and non-metric traits can be used to explore the biological/genetic relationship between populations (e.g. Betti et al. ; Irish ; Coppa et al. ; Nikita, Mattingly and Lahr ; Ricaut et al. ). Strontium isotopes detected from dental and skeletal tissues can provide valuable information regarding the movement of people during the course of a persons lifetime (e.g. Bentley ; Montgomery and Evans ; Bentley et al. ; Giblin et al. ). This paper presents the results of a pilot project where such methods were applied, for the first time, to human skeletal remains of the third and early second millennia BC from Crete; the aim is to distinguish the scale and the character of gene flow in the study area. It should be noted that the term gene flowrefers to the movement of people across the landscape and the resulting interbreeding between members of different groups (Stojanowski ; Relethford ; Weiss and Buchanan ). In this paper, gene flow is deduced by assessing the biological distance among the population samples under study, and mobility patterns are revealed through analysis of strontium isotopes within Crete.
