point is you cannot equate Slavs with R1a, especially that seems to be far from truth for south Slavs...
well, look at Pelloponese....
in Lerna/Franhtichi where you would expect lot of Slav influence, R1a is 1.8%
while haplogroup I is 21.2%
in Serbia R1a is around 15%, and haplogroup I all branches together close to 50%.... similar is in Macedonia and even more extreme in Bosnia....
Montenegro has like 7% of R1a
while non-Slavic Albanians of Macedonia who never mixed with Slavs have like 12%....
do you realize now why R1a is not = Slavs? things are more complicated than that....
Avars were probably J haplogroup...
in Caucasus there are still Avars and they are mainly J haplogroup (71.4%)
http://en.wikipedia.org/wiki/Y-DNA_haplogroups_by_ethnic_groups
part of J haplogroup in Serbia might indicate origin from Avars...
Q might be about Huns...

exactly...
actually, I think that haplogroup I might have originally spread indo-european...
I think so, because Teshub weather god (analog to Zeus in Greece) is in Hatti (pre-Hettite inhabitants of Asia minor) called Taru, and in Germanic people is Thor, while in later Hettite people same god is Tarhun, while in Baltic it is Perkunas and in Slavic is Perun...
Luwian and Hetite language would be origin of Balto-Slavic, while Hatti would be origin of Germanic...early Slavic people are of Veneti race which is I am sure about I2a2 people... and Veneti origin from Eneti of Paphlagonia... thus from Hettite state (there were other haplogroups in various regions of that state)
genetically I relate Hatti with later Getae and them with I2b1... there are two hotspots of I2b1 - germanic tribes and west of Black sea where Getae lived....
Slavic and Germanic did split from PIE rather recently in genetic timeline...
....

or mix of two...or J or E.... it is just not known...
probably...
?
all people ultimately came from Africa....
but indeed genetically speaking I is much closer to J than to R...
as for people being different, well no... culture makes people different more than genetics...
