Question about I2a1b

[Insuperable]

More than 80% of Y-dna haplogroups in Europe is seems to be of neolithic origin.

Haplogroup I is the oldest European Y-dna haplogroup and the one who actually originated in Europe. It is Paleolithic in origin.

I2a1b according to calculations and research originated in modern day southern Ukraine or northern Romania around 2500 years ago and possbly spread through Slavic expansion all the way to the Adriatic sea.
Its density is high in Croatia (Over 40% with peak in Dalmatia around 60%. Though not Croatia, in Croats from Herzegovina it makes more than 70%).


Since it has high density around the above mentioned areas is it possible that people in these areas are one of people which are closest to Mesolithic or even Paleolithic people Europe or is theirs genetic too much changed over the years despite high density?

I ask because we mostly associate Mesolithic Europeans with a certain northern groups.

They are quite mesolitich (atlantic-baltic) for their latitute, but you can find far more mesolitich people up in the North. The high density of I2a1b could be explained with a founder effect.

And with the fact that when they migrated there they mixed with the indigenous inhabitants that were high in Med and West Asian component hence their lower Atlanto Baltic score.

Anyway I did not just open the thread because of that but because of other things like

R1b is strong is Basques but they are high on med component
R1b is strong in Germanics but they have high Atlantic component
I2a1 is strong in Sardinians and they have high med component
Scandinavians have strong I1 frequencies and they have high Atlantic and maybe Baltic component...

I do have a tons of questions and I sometimes do not know will I ask a stupid questions but for example

In the distant past could we associate a certain haplogroup with a certain autosomal component? Which would for which? ....

Who would that be?
Illyrians?

Illyrians,Thracians, Dacians and maybe else.

I2a1a is liked with the atlantic component, whereas the the I2a1b is linked with the baltic one. R1a1a males spread the baltic component after the Neolitich revolution.

The I1 haplotype could be linked to both atlantic and baltic components. The R1b haplotype is of mediterranean origin.

Its actually classified I2a1a nowadays.

It has a Paleolithic lineage but it has changed and mutated so many times over the course of 40000 years that it is basically nothing alike its original ancestor.

So modern day Balkanites would not be genetically similar at all to an actual Cro-Magnon, which goes for pretty much all Europeans. Genetics has changed so much since those times naturally and by admixtures that we are completely different from them even if we descend from them by parental lineage.

I have figured that by now, Sherlock.
