surprises de la genetique: arabes et persans...
Les persans parlent une langue apparentee a des langues comme l'anglais et l'allemand, les arabes parlent une langue apparentee a des langues comme le berbere, somali et egyptien
Cependant on sait que la langue ne correspond pas tjs lineairement au groupe humain.
Des dernieres etudes genetiques ont montre que les persans d'iran ont une important admixture arabe allant jusqu'a 30-40% de leur total genome, cette admixture arabe n'est pas presente a l'exception de traces 0-1% parmi les persans de l'est de l'iran d'afghanistan et d'asie centrale ou probablement le desert iranien a joue le role de barriere.
ce qui est interessant est que ce melange genetique se voit aussi au niveau de la langue persane dont le vocabulaire, grammaire et syntaxe est fortement influencee par l'arabe.
cette admixture fait que les persans d'iran occidentale (qui forment pres des deux tiers de tous les persans) ne sont pas approches des autres peuples indo-europeens mais plutot proches des peuples du moyen orient.
voila l'etude ci dessous

Mitochondrial DNA and Y-chromosomal stratification in Iran: relationship between Iran and the Arabian Peninsula.
Terreros MC, Rowold DJ, Mirabal S, Herrera RJ.
Abstract
Modern day Iran is strategically located in the tri-continental corridor uniting Africa, Europe and Asia. Several ethnic groups belonging to distinct religions, speaking different languages and claiming divergent ancestries inhabit the region, generating a potentially diverse genetic reservoir. In addition, past pre-historical and historical events such as the out-of-Africa migrations, the Neolithic expansion from the Fertile Crescent, the Indo-Aryan treks from the Central Asian steppes, the westward Mongol expansions and the Muslim invasions may have chiseled their genetic fingerprints within the genealogical substrata of the Persians. On the other hand, the Iranian perimeter is bounded by the Zagros and Albrez mountain ranges, and the Dasht-e Kavir and Dash-e Lut deserts, which may have restricted gene flow from neighboring regions. By utilizing high-resolution mitochondrial DNA (mtDNA) markers and reanalyzing our previously published Y-chromosomal data, we have found a previously unexplored, genetic connection between Iranian populations and the Arabian Peninsula, likely the result of both ancient and recent gene flow. Furthermore, the regional distribution of mtDNA haplogroups J, I, U2 and U7 also provides evidence of barriers to gene flow posed by the two major Iranian deserts and the Zagros mountain range.
