Just i red the paper "Mapping Post-Glacial expansions: The Peopling of Southwest Asia" (here), and the interesting point is:

Due to the phylogenetic relationship between J1 and J2 markers, the TMRCAs for these are identical. The J1 and J2 split shows deepest time in the Caucasus, Syria and Turkey at 8.9 ka and 8.4 ka, respectively.

Our study has identified the Caucasus refugium as the likely source for the J1 and J2 haplogroups that now dominate Southwest Asia, and previously appeared to mark the Neolithic Revolution’s expansion into Europe. Yet, haplogroups J1 and J2 are distinctly lacking in the earlier Yamnaya samples.

they include var and freq maps to sure their claims.

The article fails to comment that there are ancient J's that confirm their claims: Satsurbila and Kotias in paleolithic Georgia (J1 and J2a), and Huto Cave in the Zagros (J2a).

The interesting case is that even if the authors complain about the apparent lack of J's in Yamnayans, there was a Mesolithic J1 in Karelia dated to about 5250 BC. As this man has now clear origins in the Caucasus it's possible to ask:

his clade arrived to Karelia from the North Caucasus after the rise of temperatures? or his clade arrived there with a Neolithic expansion from the Fertile Crescent / Caucasus that went northwards?

in whichever case as this man was J1 he was carrying surely CHG autosomals, and as Yamnayans were half CHG half EHG, there are a lot of possible similar admixtures to find out in the path to the northernmost European territory. So then, as it's stated that the (eastern) Yamnayans can't be the source for the admixture in the Corded Ware, we can find out the source pop in North Russia...?
 
The Mesolithic Karelian man with J1 doesn't have confirmed CHG ancestry. If he did have some he had little.
 
To me it's not a matter if such J man had much or less CHG admixture, as for Caucasian hunthers-gaterers Karelia was far from their homeland and to reach such land a lot of admixtures with "Russian" locals would have lowered the Caucasian component before; if instead the region was reached by Caucasian agriculturalists the people there would be scarce (land not suitable for farming neither for herding, only for good for pionner trappists).

But the case is that if Caucasians reached the northermost territory of Europe by the VI millennium, and if Caucasians left a Caucasian DNA signature in their path, and other Russian EHG samples date from such time, and if such EHG really keept a Caucasian admixture (but they are taken as pure populations...), many admixture analisys involving EHG will deliver Yamnayan-like pops, I'm wrong?
 
All that depends on how are analysed ancient pops: as pure reference or admixed - allways same question! Labellings - seemingly a lot of scientists analysed Yamanya pop as a mix between kind of CHG and EHG - on physical aspect they were roughly said "halfway" between South-Caucasus, Mesolithic HGs with a taste of Northern Neolitic pops not reductible to first both, what as a whole don't contradict the DNA results -
GENETIKER has his own criteria and its Wes-Asi
 
sorry: his 'westasian' part is very low in his Pit Grave (about 12-15%?) and his dark-blue one (what's?) I take for EHGlike is very high. But he is far from scientists works. What is sure is that the total auDNA from Caucasus was and is still very very low around the Baltic, as are rare enough the Y-J...
 
Looking at Genetiker admixtures there are not Caucasian traces among HG Karelains... but instead there is a EHG trace (20%) in Satsurblia... maybe it is taking a share of the EHG genes as EHG instead to do the contrary?

For the actual scarcity of J and Caucasian DNA in the Baltics, it could be "blamed" the Siberian waves of R1a and N.
 
Marko, modern Karelians =/= Mesolithic Karelians.

================================

Below is my recent map of the spread of PIE and of R1a and R1b haplogroups, based on archaeology and on well over 100 ancient DNA samples. I think that PIE expanded into Europe along two routes, a southern route dominated by R1b-P312 with R1b-Z2103, and a northern one dominated by R1a-M417. As for R1b-U106, it could as well go along the northern route together with R1a-M417, considering that U106 has not been found in any Bell Beaker remains thus far. The oldest known U106 is RISE98 dated to 2275-2032 BC from Lilla Beddinge in Southern Sweden (Scania), and that burial was located in Corded Ware cultural zone. Autosomally, RISE98 was more similar to other Corded Ware samples (the ones with R1a), than to any Bell Beaker sample:

if we take 20% EHG in Satsurbia (I doubt it 's so high) so we can have only 20x15/100 = 3% more of "Caucasus" in play, no more, still according to Genetiker! As long we tely on him, it doesn't change things too dramatically.

I remember Eurogenes stated the Y-R-U106 RISE98 was shifted a bit more western ('northsea'?) than the Y-R1a man found there, who was more 'eastern' or 'finnish' or something like that... I cannot find his post again.
 
MOESAN,

Actually RISE98 had just as much of "North Sea" as R1a samples.

Here are Eurogenes K15 results of ancient Scandinavian samples:

RISE61 = 2650-2300 BC, Corded Ware, R1a-Z284+
RISE94 = 2621-2472 BC, Corded Ware, R1a-Z645+
RISE71 = 2196-2023 BC, Corded Ware
RISE97 = 2025-1885 BC, Corded Ware
RISE98 = 2275-2032 BC, Corded Ware, R1b-U106+
RISE276 = 794-547 BC, Nordic Bronze Age, R1b
RISE174 = 427-611 AD, Iron Age Sweden

RISE27635,132,8619,572,877,320,0802,20000000

And these samples have not been uploaded to GEDmatch:

RISE42 = 2191-1972 BC, Corded Ware, R1a
RISE179 = 2010-1776 BC, Corded Ware, I1
RISE47 = 1499-1324 BC, Nordic BA, R1b(xP312)
RISE207 = 1493-1302 BC, Nordic BA, I1
RISE210 = 1432-1292 BC, Nordic BA, I1
RISE175 = 1395-1132 BC, Nordic BA, I1

Would be nice to upload them and see their results as well.
 
As you can see RISE98 had more of "Eastern Euro" admixture than Scandinavian R1a samples.

He had 16,41% of "Eastern Euro" - compared to 11,15% and 7,53% for two samples with R1a.

He had about as much of "North Sea" and he had actually much less of "Atlantic" than R1a men.

was shifted a bit more western ('northsea'?)

"North Sea" does not really shift you west, at least not during the Bronze Age (IIRC, Sintashta, Potapovka, Srubnaya, etc. samples from Russia also scored a lot of "North Sea"). "Atlantic" is what shifts you west. "North Sea" just shifts you north.

"West Med" and "Atlantic" really shift you west (those were the 2 main admixtures in Copper-Bronze Age Iberia).
 
Did you even bother to read Lazaridis paper? There's no mention of modern Karelians, of course.

I did read it but it was long ago. OK sorry, I will check it again.
 
As per Lazaridis, the Karelians do have ancestry from something that peaks in Neolithic Iran. The affinity can be seen as early as Hotu III. Take a look at figures 1 & 4:

http://biorxiv.org/content/biorxiv/early/2016/06/16/059311.full.pdf

Interesting. In Hotu and Belt cave, 8,000y old pottery was found, being similar to lake baikal pottery.

In Karelia, comb ware pottery was found, which originated in Liao valley in Manchu area and migrated thru Lake Baikal to Europe.
"However, calibrated radiocarbon dates for the comb-ware fragments found (e.g., in the Karelian isthmus), give a total interval of 5600 BC – 2300 BC (Geochronometria Vol. 23, pp 93–99, 2004)."

I cannot find the Eurogenes post - Surely I mistake Corded R1b with a Nordic Bronze Y-R1b, I beg your pardon, I did not find my notes - I totally agree with you this RISE98 is very "north-east" and "east" - OK too for 'northsea': these people according to me came from N-E before to specialize in N-W - I put "northsea" between (-) not sure of the Eurogenes statement in details - you and others may forget my useless post! thanks for details I had not.
 
if we take 20% EHG in Satsurbia (I doubt it 's so high) so we can have only 20x15/100 = 3% more of "Caucasus" in play, no more, still according to Genetiker! As long we tely on him, it doesn't change things too dramatically.

I have not explained it well. The EHG admixture in Satsurblia would not be a true EHG but original part of the Caucasians, to give an example it would be to find out in Europeans an African admixture of 25% if we take Mulattos as source pop.

Where are the R1b-P312 aDNA in the Steppes? I saw none so far. Only R1b-Z2103 or R1a.

Most likely in Ukraine, from which there are no any ancient Y-DNA samples so far.

1) Ancient samples of R1b:

2) Ancient samples of R1a:

Rogalin samples are from Eastern Poland, not from Ukraine. Ukraine is a "desert".
 
Remember Villabruna shares Alleles with CHG so EHG will as well. At least a little.

We will find the origins of Corded Ware and "European" R1b subclades in Sredny Stog and subsequent Ukranian BA steppe samples.

Pottery with impressed cords is first found in Sredny Stog, which also appears to have a greater affinity with the Balkan Neolithic. This is genetically exactly what Corded Ware, Srubna, and Sintashta look like as well.
