TS obviously never heard of arabs, the actual people who conquered sicily .
sicilians are mixed with arabs and some north african ( like modern moroccan , tunisians ,algerians etc.. )
the first conquest was led by 100 % pure blooded arab Asad ibn al-Furat ,the first emir of sicily was 100 % pure blooded arab Abu Fihr Muhammad ibn Abd-Allah
it's ridiculous to say that italians have black in them when in fact , north africans themselves barely have any . in fact tunisia , the country from where the conquest started have less than 1.5 % sub-saharan DNA in them ( e1b1a )
http://en.wikipedia.org/wiki/E1b1a
africans americans = 50 - 60 %
tunisia = 1.4%
italy = 0 %
the highest frequency in europe is found in majorcans , a barely noticable 3.4 %
why are some italians dark ? simple , middle eastern blood AKA Haplogroup J .
http://en.wikipedia.org/wiki/Haplogroup_J_%28Y-DNA%29
yemen = 82 %
qatar = 65 %
italy = 22 %
get some education people
