No offense to anyone, but I red so much weird things in this thread.
Red hairs are less seldom among Askhenaze Jews than among the most of Europe, OK. Red hairs can be caused by a lot of mutations (7, I think, 3 very common among red hairs, for the most in Northern Europe), I don't know the distribution of these mutations among Jews - But can we say Askenaze as a whole are light haired and light eyed and very light skinned? No, SPITE the relatively high % of red hairs - I know a lot of pops with as a mean less red haired men but more light skinned men.
oir the present question (supposed look of Jesus), today Askenaze Jews are a mix of a lot of populations and there supposed earlier population of origin is only an element in their DNA making, even if this element is surely heavy enough - On plottings of diverse systems, they plot between Southern Italians, Chypriots and Greeks - and this supposed source population (I see myself in Near-East, evidently) was already a mixed one, where roughly said Natufians and Anatolian people were the basis, enriched later by people from Iran AND even later (MLBA, I think) by people from Caucasus, even North Caucasus. At the look level, you cannot cluster completely pops of Palestine with pops of the Lebanon, neighbours however -
So, too much unknown elements for me in this question concerning the depictation of Jesus; this post is just to try to show the numerous obstacles I see here.
