Origin and spread of human mitochondrial DNA haplogroup U7
Sahakyan, Hovhannes; Hooshiar Kashani, Baharak; Tamang, Rakesh; Kushniarevich, Alena; Francis, Amirtharaj; Costa, Marta D.; Pathak, Ajai KumarHuman mitochondrial DNA haplogroup U is among the initial maternal founders in Southwest Asia and Europe and one that best indicates matrilineal genetic continuity between late Pleistocene hunter-gatherer groups and present-day populations of Europe. While most haplogroup U subclades are older than 30 thousand years, the comparatively recent coalescence time of the extant variation of haplogroup U7 (~16-19 thou...
Ethiopian mitochondrial DNA heritage: tracking gene flow across and around the ...
Kivisild, Toomas; Reidla, Maere; Metspalu, Ene; Rosa, Alexandra; Brehm, António; Pennarun, Erwan; Parik, Jüri; Geberhiwot, Tarekegn; Usanga, EsienApproximately 10 miles separate the Horn of Africa from the Arabian Peninsula at Bab-el-Mandeb (the Gate of Tears). Both historic and archaeological evidence indicate tight cultural connections, over millennia, between these two regions. High-resolution phylogenetic analysis of 270 Ethiopian and 115 Yemeni mitochondrial DNAs was performed in a worldwide context, to explore gene flow across the Red and Arabian S...
