Reconstruction of human subsistence and husbandry strategies from the Iberian Early Neolithic: A stable isotope approach
Objectives The Early Neolithic involved an important social and economic shift that can be tested not only with the material culture, but also through biomolecular approaches. The Iberian Peninsula presents few Early Neolithic sites where fauna and humans can be analyzed together from an isotopic perspective. Here we present an isotopic study on the site of Cueva de Chaves as an example for understanding the dietary and economical changes that took place during Early Neolithic in Iberia. Material and methods Here we apply carbon and nitrogen stable isotope analysis to bone collagen from 4 humans and 64 faunal samples from 14 different species. The large dataset belongs to the same unique ch…
HLA-A, -B and -DRB1 allele frequencies in Cyrenaica population (Libya) and genetic relationships with other populations.
Abstract The frequencies of HLA-A, HLA-B and HLA-DRB1 alleles in 118 unrelated Libyans from Benghazi (Cyrenaica) were analysed using high resolution typing and compared with other populations. Their relatedness has been tested by correspondence analyses and principal component analysis. The most frequent HLA-A alleles were A ∗ 02:01:01:01 (15.7%), A ∗ 01:01:01:01 (11.4%) and A ∗ 03:01:01:01 (9.3%). For the HLA-B locus, the commonest allele was HLA-B ∗ 50:01:01 (14.4%) followed by B ∗ 51:01:01 (9.8%) and B ∗ 08:01:01 (6.4%). For the HLA-DRB1 locus, the commonest was HLA-DRB1 ∗ 07:01:01:01 (16.9%) followed by DRB1 ∗ 03:01:01:01 (13.6%) and DRB1 ∗ 13:02:01 (9.3%). The most frequent two-locus h…
