As Ushtari mentions, Coon is the one that has travelled around studying and measuring people unlike you, what I'm talking about isn't any idea or theory set forward by Coon, it's simple measurements and studies done by him from which he has gotten certain numbers concerning height and pigment, there's no ideas here just plain facts presented as numbers.I dont believe anything about Coon ideas. His ideas is laughable..
Serbians don't look like regular Slavs on average, they're looks are Balkanid although of course with some non-Balkan influence, more specifically I'd say they're Central-Balkanids, something between Western-Balkan and Eastern-Balkan showing influences from both.Serbians might be swarthy but they looks like a regular Slavic/Eastern European whereas Albanians doesn't really looks Eastern European/Slav because they lack Slavic admixture.
About 1/3 of the toponyms are Slavic or of Slavic deriviation, these are mostly found in Southern-Albania, and according to genetics they have more Slavic influence than Gheg Albanians, who show impressively small amounts of Slavic tied haplogroups, R1a1 in Kosovars is at about 4%. Most likely the Albanians from Northern-Albania proper are going to show even lesser amounts of Slavic influence.There are great many Slavic toponyms in Albania, which suggests they too have mixed with Slavs. Mind you, most of Greece was also Slavic at one point.
