Why didn't Indo Europeans dominate Scandinavia with R haplogroup?

[Senpai]

I've always found this interesting..

Scandinavia has a high genetic admixture of Indo European DNA, Norway having some of the highest in Europe overall, so why isn't R haplogroups more common today?

I think there's a few theories that could make sense.

1. Some inhabitants in pre-PIE Scandinavia could have made a deal with for their families continuance, or had great sums of minerals or knowledge of some sort of craft that only they could pass on.

2. The Invaders thought highly of the population already in Scandinavia, maybe they looked or acted similar

I'm not sure. What do you think? OR what do you know? Because I haven't researched this enough yet, and there could be more solid info.

Normally I'm too serious for stuff like this, but fuk.
That was perfect, lmao

IEan speakers who arrived in Scandinavia didn't come directly from Yamnaya. They came from CWC which was derived from Yamnaya. And CWC was already mixed with the European native population.

Also, there was not a huge migration of IEan people in Scandinavia, since Scandinavia is not really heavy populated. Scandinavians had intensified trading system with the CWC people and they got their IEan dna from CWC (Corded Ware) people by mixing with them voluntarily. So their Scandinavian men married CWC women.

The IE people had different culture than the WHG people. Probably the incoming groups could not replace many of these strongly entrenched people but rather mixed slowly.

Actually even in Scandinavia, Rs are dominant except Sweden.

Perhaps, IE invaders relied on goat, ox herding and agricultural more. Scandinavia may not be so suitable for these and this may be why Hunter Gatherer y dnas didn't go extinct. I always thought hunter gathering makes societies more robust by natural selection during hunting. Meanwhile, agriculturalism makes more gracile and neotenous due to lack of selection.

It just doesn't make much sense to me, as the IE were a very paternal people, who often left women behind as they moved. In most IE societies, prior male populations in new lands were pretty much obliterated, and replaced, which would explain R haplogroup prevalence, and IE admixture overall in modern times, but women don't murder women, so the replacement would never be as deep rooted as it would be if Corded Ware men would have took Scando brides. It doesn't explain how Scandinavia's IE admixture is so high. Unless I'm just missing something here.

Yes and no. The IE people had different culture than the WHG people, but not a lot people lived in Scandinavia. CWC IEans from Germany, Denmark could easily replace Scandinavian (SHG) WHG groups by mass migration, but they didn't. Maybe because they were not really interested in those much colder places.

Due to climate conditions not many people wanted to live in Scandinavia even today the population in Scandinavia is not that high compared to Central Europe. It is simply too cold and depressing up there.

R1 in Finland is low.
