I think that we have to see the study, to say anything more. I suspect that in text under label "indo-europeans" are meant Russians and Balts. According to latest studies made, these are the closest genetic populations to Finns. Swedes are not so closely related to Finns, although still close.
According to previous studies, and results in commercial genetic testing company 23andMe, Saami have quite big distance from Finns and everybody else. I am astounished to see, how related to Volga populations the Saami might be. Or is it described in this study at all? Maybe this study is just about the "uralic" percentages in populations, which doesn't tell much about the degree of relatedness of populations. Well, let's see.
I myself have taken genetic test in genetic testing compny 23andMe. I have partial Khanty ancestry. I am quite distant from Finns, Balts and everybody else. Basically I am in "middle of nowhere". Maybe later I will post charts, where I am, and where are also Finnish people in Eurasian dimensions.
T mtDNA comes from Mesopotamia (Wikipedia). Mesopotamia was located in Asia. Today Iraq and Syria are located in this area.
Luhta, do you have Khanty ancestry? Finns are genetically closer to eastern relatives (Finno-Ugrics/Samoyed people), than Samis are. Even Icelanders and Danes are genetically closer to Samoyed people. Samis don't have much eastern genes, it's very interesting..
Indo-Europeans (their languages) come from Central Asia, so they are Asians? And what does it mean if someone is an Asian? Chinese or Arab? Language? Residence? Or what?
