Biological history of an Italian prehistoric community and the population of the central Italy during the 1st millennium BCE.

Abstract

Understanding the population of Central Italy during the 1^st millennium BCE is a crucial topic in the biological history of the Mediterranean basin. This period saw the emergence of the Etruscan and Roman cultures which had a significant impact on the bio-cultural history of the region. In this study, we analyse a prehistoric population from Caracupa (Iron Age, Latium, Central Italy). The results suggest an overall good level of health for the population. Despite this, some musculoskeletal changes related to biomechanical stressors were observed, probably as the result of strenuous physical activity. The results of a Simple Matching analysis of intragroup distance distributions suggest potential model of kinship structures and lineages. This may be due to the relative geographic isolation of the Caracupa population. Furthermore, in order to investigate the wider population of Central Italy during the 1^st millennium BCE, we have constructed a population pattern using genetic and phenotypic skeletal and dental traits. The comparison between Central Italy and more isolated populations indicated a divergence between the Western and Eastern sides of Central Italy. However, we do not exclude a probable common genetic substratum for all Central Italian populations during the 1^st millennium BCE.
