[QUOTE]Originally posted by the lioness,: [QB] [QUOTE]Originally posted by xyyman: [qb] Lioness I know you want traffic. But Look at the land mass designated West Asia according to DNATribes. It IS the Levant, Turkey etc. NOT Saudi Arabia and Yemen. I know you are mathematically challenged but I thought you had a better handle on geography. BTW - DNA Tribes references SNPs, not STR and HG. J2 maybe Levantine but J1 is not. Point of origin for J1 is contradictory either Yemen or Ethiopia. Either way J1 is Black owned. [/qb][/QUOTE]J1 developed in the Southern Levant and is likely "Semitic" in origin. It has remained situated primarily in Middle Eastern populations and in Northern African Arab populations. Rare in Europeans, with the exception of Jewish Europeans, who have it at a frequency of 14-18%. Haplogroup J-P209 is believed to have arisen roughly 31,700 years ago in Southwest Asia (31,700±12,800 years ago according to Semino 2004). [b]Origin, diffusion, and differentiation of Y-chromosome haplogroups E and J: inferences on the neolithization of Europe and later migratory events in the Mediterranean area. Semino [/b]O, Magri C, Benuzzi G, Lin AA, Al-Zahery N, Battaglia V, Maccioni L, Triantaphyllidis C, Shen P, Oefner PJ, Zhivotovsky LA, King R, Torroni A, Cavalli-Sforza LL, Underhill PA, Santachiara-Benerecetti AS. Source Dipartimento di Genetica e Microbiologia, Universita di Pavia, 27100 Pavia, Italy. semino@ipvgen.unipv.it Abstract The phylogeography of Y-chromosome haplogroups E (Hg E) and J (Hg J) was investigated in >2400 subjects from 29 populations, mainly from Europe and the Mediterranean area but also from Africa and Asia. The observed 501 Hg E and 445 Hg J samples were subtyped using 36 binary markers and eight microsatellite loci. Spatial patterns reveal that (1). the two sister clades, J-M267 and J-M172, are distributed differentially within the Near East, North Africa, and Europe; (2). J-M267 was spread by two temporally distinct migratory episodes, the most recent one probably associated with the diffusion of Arab people; (3). E-M81 is typical of Berbers, and its presence in Iberia and Sicily is due to recent gene flow from North Africa; (4). J-M172(xM12) distribution is consistent with a Levantine/Anatolian dispersal route to southeastern Europe and may reflect the spread of Anatolian farmers; and (5). E-M78 (for which microsatellite data suggest an eastern African origin) and, to a lesser extent, J-M12(M102) lineages would trace the subsequent diffusion of people from the southern Balkans to the west. A 7%-22% contribution of Y chromosomes from Greece to southern Italy was estimated by admixture analysis. [b]M81 reveals recent gene flow from North Africa. Distinct histories of J-M267* lineages are suggested: an expansion from the Middle East toward East Africa and Europe and a more-recent diffusion (marked by the YCAIIa-22/YCAIIb-22 motif) of Arab people from the southern part of the Middle East toward North Africa[/b] [/QB][/QUOTE]
