[QUOTE]Originally posted by xyyman: [QB] I told you so.....R1b M269 can be considered having an African origin. There is no such thing as "European" genes or invasion from the Steppes of Asia. Modern Europeans are depigmented Africans ---- Quotes: In 2009, [b]ancient “Guanches” samples were genetically analyzed[/b] from Tenerife, La Gomera, El Hierro and Gran Canaria Islands and [b]historical pre-Spanish Conquest remains[/b] from all Islands except from Lanzarote (Fregel et al., 2009). Authors conclude that there was a higher frequency of male genetic “North African” markers and a lower frequency of male genetic “European markers”. Authors again [b]conclude that this (R1b1b2, M269) marker and frequency in ancient “Guanches” shows that a “Guanche” (mostly North African) male substitution was achieved because of Spanish conquest[/b]. However, they do not take with account that this marker is high in western Atlantic Europeans particularly in the British Isles, Portugal, French Britain and Northern Spain (for a review see [Oppenheimer, 2007]). [b]Thus, the “North African” origin of this Y chromosome marker should be considered Atlantic (Europe and British Isles)****** including “North Africa” ******and Canary Islands[/b] Origin of First Canary Islands Inhabitants according to HLA genetics. Our present day Tenerife Islanders population HLA studies show that an admixture of European (mainly Atlantic) and North African population is found (Table 2, and Table 3; Fig. 4 and Fig. 5). These findings may not reflect the First Canary Islands Inhabitants genetic features. This is because[b] only Tenerife Island is analyzed [/b] and also because different Canary Islands invasions, particularly Spanish conquest in XV century AD, may have altered the initial population genetic composition. However, autosomal HLA characters common to Iberian and Berbers are formed (Arnaiz-Villena et al., 1997) and conjoint autosomal, mtDNA and Y chromosome markers [b]study revealed a gene flow across the Strait of Gibraltar; it was ongoing ****in high rates ****since pre-Neolithic times (Currat et al., 2010).[/b] This makes[b] difficult a distinction between Iberian and North West Africans [/b]on the bases of both autosomal and sex chromosomes markers. Thus,[b] genetic discussion about whether Iberians or North African Berbers where the First Canary Inhabitants is artificial, [/b]when only genetic markers are considered. In fact, the bias towards high frequencies of European Y chromosomes and mtDNA African markers in present day Canary Islanders have been interpreted a “Guanche” male substitution by Normand and Spanish XIV-XV century conquerors (Maca-Meyer et al., 2004, Maca-Meyer et al., 2003b).
