In 1951, S. Sergi analysed human skeletal remains from the Fezzan dating from the end of the Pastoral period up to the Roman period in the first centuries AD. Sergi concluded that the Garamantes were mostly of '
Mediterranean' type, similar to modern Berbers, which he termed 'Euroafrican'. He also found an influx of '
Negroid' types and an increase of 'mixed' types dating mostly from the Roman period. In a review of the skeletal evidence analysed by Sergi, M.C. Chamla (1968) found that 46.6% of the individuals were of 'Eurafrican' type (closely related to Berbers), 26.6% were of mixed Eurafrican-Negroid type, and 26.6% were of 'a more predominantly Negroid' type. According to
David Mattingly et al. (2003): Francesca Ricci et al. (2013) analysed skeletal samples from the Garamantian site of Fewet in the Fezzan and found that they were similar to the
Mediterranean 'Euroafrican' type identified by Sergi, but with some evidence for gene flow from (probably) sub-Saharan populations, "similarly to what Sergi (1951) suggested discussing the possible hybridization between the “Mediterranean” Group I and the “
Negroid” Group IV." This gene flow was more evident in the female skeletons, suggesting an influx of non-local females possibly from the
Sahel region.
Marta Mirazón Lahr et al. (2010) conducted research on skeletons from
Fezzan dating from the Roman era and found that the skeletons clustered most closely with Neolithic Sahelian samples from
Chad,
Mali, and
Niger, and secondarily to Roman Egyptians from Alexandria and Nubians from Soleb. 1st millennium BC samples from Algeria and Tunisia were somewhat more distant but still rather close to the Fezzan skeletons. Lahr et al. concluded that the Garamantes had connections with both the
Sahel and
northern Africa. Efthymia Nikita et al. (2011) examined the biological affinities of the Garamantes using cranial nonmetric traits and the Mean Measure of Divergence and Mahalanobis D(2). They were compared to other North African populations, including the Egyptian, Algerian, Tunisian and Sudanese, roughly contemporary to them. Overall, three clusters were identified: (1) the Garamantes, (2) Gizeh and Kerma, and (3) Soleb, Alexandrians, Algerians and Carthaginians. The analysis concluded that the Garamantes were isolated, with the Sahara playing a role as a barrier to geneflow. The distance between the Garamantes and their neighbors was high and the population appeared to be an outlier. The remains of a young
sub-Saharan African woman, which has been dated to the 1st millennium BC and possessed a
lip plug that is associated with Sahelian African groups, was buried among other Sub-Saharan Africans that were part of the heterogenous Garamantian population. Power et al. (2019) states: "This ornament demonstrates that some Garamantes individuals shared aspects of their material culture with Sahelian societies more broadly, either through migration or contact, while their burial within Garamantes cemeteries shows their integration into the normative funerary rituals of contemporary Garamantian society. The combination of morphometric and isotopic work further reinforces the view that Garamantian society included individuals of diverse geographical origin, some of whom may have been first generation Trans-Saharan migrants." The craniometric results also identified another sub-group within the Garamantes buried in the Wadi al-Ajjal, with a morphology that is widely observed among
Mediterranean people. ==Language==
