X-Linked Mtmr8 Diversity And Evolutionary History Of Sub-Saharan Populations, Damian Labuda, Vania Yotova, Jean-François Lefebvre, Claudia Moreau, Gerd Utermann, Scott M. Williams

Dartmouth Scholarship

The genetic diversity within an 11 kb segment of the MTMR8 gene in a sample of 111 sub-Saharan and 49 non-African X chromosomes was investigated to assess the early evolutionary history of sub-Saharan Africans and the out-of-Africa expansion. The analyses revealed a complex genetic structure of the Africans that contributed to the emergence of modern humans. We observed partitioning of two thirds of old lineages among southern, west/central and east African populations indicating ancient population stratification predating the out of Africa migration. Age estimates of these lineages, older than coalescence times of uniparentally inherited markers, raise the question whether contemporary …

The nucleocytoplasmic large DNA viruses (NCLDVs) comprise a monophyletic group of viruses that infect animals and diverse unicellular eukaryotes. The NCLDV group includes the families Poxviridae, Asfarviridae, Iridoviridae, Ascoviridae, Phycodnaviridae, Mimiviridae and the proposed family ‘‘Marseilleviridae’’. The family Mimiviridae includes the largest known viruses, with genomes in excess of one megabase, whereas the genome size in the other NCLDV families varies from 100 to 400 kilobase pairs. Most of the NCLDVs replicate in the cytoplasm of infected cells, within so-called virus factories. The NCLDVs share a common ancient origin, as demonstrated by evolutionary reconstructions that trace approximately 50 genes encoding …

Animal Skeletal Remains Of The Theodosius Harbor: General Overview, Vedat Onar, Gülsün Pazvant, Hasan Alpak, Nazan Gezer İnce, Altan Armutak, Zeynep Sevi̇m Kiziltan

Turkish Journal of Veterinary & Animal Sciences

Archaeological excavations at the site of Yenikapı, the most important main station for Metro and Marmaray projects on the European side of İstanbul, were started in 2004 with the discovery of numerous shipwrecks, amphorae, and skeletal remains belonging to animals. The findings from the excavations conducted by the İstanbul Archaeological Museums of the General Directorate of Cultural Heritage and Museums proved that this site, known in the Ottoman period as 'Langa Bostanları', was actually the ancient harbor of Theodosius. The archeological material and animal skeletal residues, mostly of horse origin, were found side by side in excavations initiated in 2004 …
