Is the evaluation of millennial changes in stature reliable? A study in southern Europe from the Neolithic to the Middle Ages

Analyses of stature variation in prehistoric and historical populations encounter considerable problems of reliability of the comparisons. To properly compare the results of different studies, it is necessary to conduct a systematic review of the chronological and cultural context of the skeletal series used and identify the most appropriate method to calculate stature values, since stature reconstruction formulae are specific for certain times and places. Stature variations in the population of Sardinia (a Mediterranean island now part of the Italian Republic but considered separately given its unique genetic structure) from the Neolithic to the Modern Period were studied to evaluate the intensity of millennial changes. The results were then compared with the values of coeval skeletal series reported in the literature for other Southern European countries (Italy, Spain, Portugal). We used Sardinian skeletal series with radiocarbon dates or from culturally well-defined archeological contexts. The osteometric measurements were taken on femora of adults who had completed growth and who did not present evident pathological conditions. The data we collected and analyzed indicate that the conditions are lacking to reliably identify a common trend in millennial changes among the considered populations of southern Europe.
