- day ▁European ▁population ▁with ▁the ▁Th ra cian ▁population ▁has ▁resulted ▁that ▁the ▁Italian ▁( 7 . 9 % ), ▁the ▁Alban ian ▁( 6 . 3 %) ▁and ▁the ▁Greek ▁( 5 . 8 %) ▁have ▁shown ▁a ▁bias ▁of ▁closer ▁[ mt D na ] ▁gen etic ▁kin ship ▁with ▁the ▁Th ra cian ▁individuals ▁than ▁the ▁Roman ian ▁and ▁Bulgar ian ▁individuals ▁( only ▁ 4 . 2 %). ▁ ▁Aut os om al ▁DNA ▁ ▁Analysis ▁of ▁aut os om al ▁DNA , ▁which ▁anal ys es ▁all ▁gen etic ▁components ▁has ▁revealed ▁that ▁few ▁rig id ▁gen etic ▁dis continu ities ▁exist ▁in ▁European ▁populations , ▁apart ▁from ▁certain ▁out liers ▁such ▁as ▁Sa ami , ▁S ard ini ans , ▁Bas ques , ▁Fin ns ▁and ▁Kos ov ar ▁Alban ians . ▁They ▁found ▁that ▁Alban ians , ▁on ▁the ▁one ▁hand , ▁have ▁a ▁high ▁amount ▁of ▁identity ▁by ▁descent ▁sharing , ▁suggesting ▁that ▁Alban ian - spe akers ▁derived ▁from ▁a ▁relatively ▁small ▁population ▁that ▁expanded ▁recently ▁and ▁rapidly ▁in ▁the ▁last ▁ 1 , 5 0 0 ▁years . ▁On ▁the ▁other ▁hand , ▁they ▁are ▁not ▁wh olly ▁isolated ▁or ▁end og am ous ▁because ▁Greek ▁and ▁Mac ed onian ▁samples ▁shared ▁much ▁higher ▁numbers ▁of ▁common ▁ancest ors ▁with ▁Alban ian ▁speak ers ▁than ▁with ▁other ▁neighb ors , ▁possibly ▁a ▁result ▁of ▁historical ▁migr ations , ▁or ▁else ▁perhaps ▁smaller ▁effects ▁of ▁the ▁S lav ic ▁expansion ▁in ▁these ▁populations
