“…However, fat-tailed sheep predominate in northeast Africa today. Rock paintings from the Lake Turkana basin dated to 4500-3500 BP depict thin-tailed sheep [6,7], which today mainly occur in Ethiopia (Benishangul-Gumuz and North Gondar regions), Sudan and West Africa. Rock paintings from eastern Ethiopian highlands show fat-tailed sheep alongside humpless cattle [8].…”

“…The top significant window at this region spanned five genes (NR6A1, NR5A1, ADGRD2, PSMB7, and NEK6) and the topmost significant position was close to NR5A1. The expression of NR5A1 drives Leydig cell differentiation from progenitor cells (Barsoum and Yao, 2010), thus initiating steroidogenesis (Martin and Tremblay, 2010). In mice, NR5A1 has been shown to be essential in the formation of pituitary, gonad and adrenal glands (Luo et al, 1994).…”

With climate change bound to affect food and feed production, emphasis will shift to resilient and adapted indigenous livestock to sustain animal production. However, indigenous livestock comprise several varieties, strains and ecotypes whose genomes are poorly characterized. Here, we investigated genomic variation in an African thin-tailed Desert Sheep sampled in Sudan, using 600K genotype data generated from 92 individuals representing five ecotypes. We included data from 18 fat-tailed and 45 thin-tailed sheep from China, to investigate shared ancestry and perform comparative genomic analysis. We observed a clear genomic differentiation between the African thin-tailed Desert Sheep and the Chinese thin-tailed and fat-tailed sheep, suggesting a broad genetic structure between the fat-tailed and thin-tailed sheep in general, and that at least two autosomal gene pools comprise the genome profile of the thin-tailed sheep. Further analysis detected two distinct genetic clusters in both the African thin-tailed Desert Sheep and the Chinese thin-tailed sheep, suggesting a fine-scale and complex genome architecture in thin-tailed sheep. Selection signature analysis suggested differences in adaptation, production, reproduction and morphology likely underly the fine-scale genetic structure in the African thin-tailed Desert Sheep. This may need to be considered in designing breeding programs and genome-wide association studies.

“…Scrapers are equally diverse and like cores they lack standardization or apparent regional styles. Inter-and intra-site variability might indicate highly flexible lifeways across the Early Holocene, or that lithic technology remained largely expedient as more economic emphasis went into organic fishing technologies best exemplified by the proliferation of barbed bone points at lakeshore sites (Barthelme, 1985;Phillipson, 1977;Wright et al, 2015). Unstandardized crescents were maintained to accommodate opportunistic terrestrial hunting and inter-personal conflict .…”
