I0099 (Halberstadt_LBA)
This single individual from the Late Bronze Age could be assigned to haplogroup R1a1a1b1a2 based
on S204:16474793G→A, and to upstream R1a1a1b1a (S198:15588401T→C), and R1a1a1b1
(PF6217:21976303T→A), and R1a1a1b (S224:8245045C→T, S441:7683058G→A). It is thus more
derived than the earlier Corded Ware I0104 individual and belongs firmly within the present-day
European variation of R1a Y-chromosomes.

I0099/HAL36C (grave 40, feature 1114, 1113-1021 calBCE, MAMS 21484)
was buried in right-handed flexed position, head SSW, facing SE. Two decorated LBK pots
and two undecorated globular pots were found above the grave but it was not clear whether
they were part of the burial or the back filling. Thus, the skeleton was also originally thought
to be part of the LBK burial series found at the same site, but subsequent radiocarbon dating
performed for this study indicated a much younger date, placing this individual within the
Late Bronze Age Urnfield culture of the Mittelelbe-Saale region.

Powtarzam raz jeszcze, wbrew temu co autorzy napisali nie jest to Z280 ani R1a1a1b1a2
Mieli wyraźny problem z kwalifikacją osobnika.

Gdzie tutaj jest Z280? Ano nie ma... jest tylko mutacja S204. Aby było to R1a1a1b1a2 muszą wystąpić 2 mutacje: S204/Z91, S466/Z280. A tutaj jest tylko 204. Jest to rzadka grupa Z91... istnieje problem z jej kwalifikacją; natomiast są przesłanki ze jest to grupa jakoś powiązana z Bałtosłowianami
Pozostałe mutacje obecne u łuzyczanina to staroindoeuropejskie.

Nie masz pojęcia o czym piszesz.
Haplogrupa R1a1a1b1a2 to jest to samo co haplogrupa R1a-Z280. SNP S204 jest równoważny Z280. Wszyscy, którzy mają Z280 mają też S204 i vice versa. Gdyby tak nie było mielibyśmy wyodrębnioną nową haplogrupę.

R1a1a1b1a2 (S204/Z91, S466/Z280) — является восточноевропейской меткой (возможно, балто-славянской), встречается по всей Центральной и Восточной Европе, западная граница распространения протягивается от Восточной к Юго-западной Германии и далее к Северо-восточной Италии, распространена у русских, украинцев, поволжских татар и других. Внутри ветви выделяется несколько кластеров, изученных пока лишь в общих чертах: восточно-славянский, балтский, померанский, польский, карпатский, восточно-альпийский, чехословацкий и другие.

H23 (C10211T) is estimated to be about 3000 years old based on diversity of present day samples, however, there is an H23 sample from ancient remains from the early LBK farmer culture found at Halberstadt-Sonntagsfeld, Germany dated to about 7000 years ago.
H23 has 30 samples including: 5 from Germany, 2 from Sweden, 2 from England, 2 from Ireland, 2 from Netherlands, 2 from Russia and 1 each from Poland, Scotland, and Czech. While H23 was present in Germany at least 7000 years ago, the most recent common ancestor of the people in the H Subclade Discovery project probably originated in an early Germanic tribe in northern Europe around 3000 years ago.

Czyli z tego co rozumiem H23 ma co najmniej 7000 lat (i co jeszcze ciekawsze to sprzed 7000 lat odkryto w tym samym miejscu - koło Halberstadt), ale zaczęło ekspansję dopiero 3000 lat temu - wtedy gdy żył nasz Bałtosłowianin, tudzież "an early Germanic tribe in northern Europe".

Na to wyglada ze nasi lowcy-zbieracze zaczeli integrowac sie ze wstegowcami czyli wczesnymi rolnikami

gdzie panowal matriarchat z mtDNA H23?

To H23 to tylko jeden z wielu rodzajów mtDNA wśród wstęgowców, mtDNA jest zwykle jeszcze bardziej zróżnicowane niż Y-DNA.

I0104 (Corded_Ware_LN)
This individual was assigned to haplogroup R1a1a1 based on mutation M417:8533735G→A, and also
had six upstream mutations placing it in haplogroup R1a1a (M515:14054623T→A,
M198:15030752C→T, L168:16202177A→G, M512:16315153C→T, M514:19375294C→T, and
L449:22966756C→T) and four mutations placing it in haplogroup R1a1 (L145:14138745C→A,
L62:17891241A→G and L63:18162834T→C, L146:23473201T→A).
We could further exclude lineages R1a1a1a (CTS7083:17275047T→G) and R1a1a1b
(S441:7683058G→A, S224:8245045C→T), so I0104 could be more precisely described as
R1a1a1*(x R1a1a1a, R1a1a1b).
Three related individuals belonging to haplogroup R1a were previously described from Corded Ware
individuals from Eulau, Germany3. The R-M417 haplogroup has an estimated TMRCA of ~5,800
years ago4, which indicates that I0104 lived about 1.5ky after the foundation of this lineage from
which the vast majority of modern R1a-related chromosomes from across Eurasia are descended.
More than 96% of modern European R-M417 Y-chromosomes belong4 to lineage R1a1a1b1a-Z282
which can be excluded for individual I0104, both indirectly, based on its ancestral state for the
upstream mutation defining haplogroup R1a1a1b, and directly, as the individual was ancestral for the
Z282 polymorphism itself (15588401T→C). Thus, I0104 was related to the modern European set of
R1a Y-chromosomes but did not belong to the more dominant group within this set.

Po prostu w Y-DNA panuje winner takes it all.

Swedish-Norwegian Battle Axe culture, or the Boat Axe culture, appeared ca. 2800 BC and is known from about 3000 graves from Skåne to Uppland and Trøndelag. While Swedish writer Herman Lindqvist has referred to this as the "Age of crushed skulls", there is no indication that this was an especially violent time, and most of the "crushing" happened post-mortem in the ground.[dubious – discuss] The "battle-axes" were primarily a status object.

Pośród R1a jest jedna Z280 datowana na 3000-3100 lat z terenu Niemiec(pogranicze b.NRD i NRF), obecnie Z280 rozciąga się od b.NRD, poprzez Europę środkową (także Chorwacja, Słowenia) po Rosję.
Druga próbka, to M417, ojcowska wszystkich kładów, także tych indo-aryjskich Z93(!), wiek w przybliżeniu 4400 lat, znaleziona w Niemczech, rowniez pogranicze b.NRD i NRF.
Trzecia najstarsza, aż z północnej Rosji, z Kareli, reliktowa R1a1, potocznie dziadek M417, datowana na 7000-7500 lat.

Wnioski z tego płynące są zgodne z najbardziej spodziewanym scenariuszem, jaki wynikał z badania obecnej populacji, a mianowicie widac jak na dłoni, chociaż nie to było celem pracy, że R1a wyewoluował w Europie środkowej. (...)

Whole Y-chromosome sequence analysis of eight R1a and five R1b individuals suggests a divergence time of ~25 000 (95% CI: 21 300–29 000) years ago and a coalescence time within R1a-M417 of ~5800 (95% CI: 4800–6800) years.

A consensus has not yet been reached on the rate at which Y-chromosome SNPs accumulate within this 9.99Mb sequence. Recent estimates include................ one SNP per: ~100 years,58 122 years,4 151 years5 (deep sequencing reanalysis rate), and 162 years.59 Using a rate of one SNP per 122 years, and based on an average branch length of 206 SNPs from the common ancestor of the 13 sequences, we estimate the bifurcation of R1 into R1a and R1b to have occurred ~25 100 ago (95% CI: 21 300–29 000). Using the 8 R1a lineages, with an average length of 48 SNPs accumulated since the common ancestor, we estimate the splintering of R1a-M417 to have occurred rather recently, ~5800 years ago (95% CI: 4800–6800). The slowest mutation rate estimate would inflate these time estimates by one third, and the fastest would deflate them by 17%.

we estimate that diversification downstream of M417/Page7 occurred ~5800 years ago. This suggests the possibility that R1a lineages accompanied demic expansions initiated during the Copper, Bronze, and Iron ages, partially replacing previous Y-chromosome strata, an interpretation consistent with albeit limited ancient DNA evidence

We measured R1a haplogroup frequency by population (Supplementary Table 4). Of the 2923 hg R1a-M420 samples, 2893 were derived for the M417/Page7 mutations (1693 non-Roma Europeans and 1200 pan-Asians), whereas the more basal subgroups were rare. We observed just 24 R1a*-M420(xSRY10831.2), 6 R1a1*-SRY10831.2(xM198), and 12 R1a1a1-M417/Page7*(xZ282,Z93). We did not observe a single instance of R1a1a-M198*(xM417,Page7), but we cannot exclude the possibility of its existence. Of the 1693 European R1a-M417/Page7 samples, more than 96% were assigned to R1a-Z282 (Figure 2), whereas 98.4% of the 490 Central and South Asian R1a lineages belonged to hg R1a-Z93 (Figure 3), consistent with the previously proposed trend.31 Both of these haplogroups were found among Near/Middle East and Caucasus populations comprising 560 samples.

This raises the possibility of a wide and rapid spread of R1a-Z282-related lineages being associated with prevalent Copper and Early Bronze Age societies that ranged from the Rhine River in the west to the Volga River in the east55 including the Bronze Age Proto-Slavic culture that arose in Central Europe near the Vistula River.56 It may have been in this cultural context that hg R1a-Z282 diversified in Central and Eastern Europe. The corresponding diversification in the Middle East and South Asia is more obscure. However, early urbanization within the Indus Valley also occurred at this time57 and the geographic distribution of R1a-M780 (Figure 3d) may reflect this.
