New Iberian paper with Celtiberian samples out!

[Token]

Very interesting paper with Celtiberian, Visigothic, Iberian and Tartessian genomes. I'm going to read it carefully and post a summary soon.

We assembled genome-wide data from 271 ancient Iberians, of whom 176 are from the largely unsampled period after 2000 BCE, thereby providing a high-resolution time transect of the Iberian Peninsula. We document high genetic substructure between northwestern and southeastern hunter-gatherers before the spread of farming. We reveal sporadic contacts between Iberia and North Africa by ~2500 BCE and, by ~2000 BCE, the replacement of 40% of Iberia’s ancestry and nearly 100% of its Y-chromosomes by people with Steppe ancestry. We show that, in the Iron Age, Steppe ancestry had spread not only into Indo-European–speaking regions but also into non-Indo-European–speaking ones, and we reveal that present-day Basques are best described as a typical Iron Age population without the admixture events that later affected the rest of Iberia. Additionally, we document how, beginning at least in the Roman period, the ancestry of the peninsula was transformed by gene flow from North Africa and the eastern Mediterranean.

Cool so I gather that first wave 40% replacement 100% Y-DNA replacement may not have changed the language anywhere, but it was later celtic waves that did!

Yeah, like i've been saying over and over, Urnfield was the culture that spread Celtic languages to Western Europe.

28 to 43% in three individuals at
La Hoya in the north where Indo-European
Celtiberian languages were likely spoken (fig. S6
and tables S11 and S12). This trend documents
gene flow into Iberia during the Late Bronze
Age or Early Iron Age, possibly associated with
the introduction of the Urnfield tradition (18).

It's a bit late here to read, but is it the whole articale? Seems to be a bit small.

The Iron Age kit I posted from Southern Portugal was essentially a Mediterranean shifter Basque

Yeah, very objective paper. Olalde covered basically the entire genetic history of Iberia with 4 pages.

[Bellbeaking]

i was wrong, the basques did receive the second wave of steppe ancestry, somehow they got beaker'd celt'd but kept their language hmmm

[Peterski]

Any info about Y-DNA haplogroups associated with Celtiberians, Visigoths, etc.?

Some excerpts from Supplementary Info:

"Two Bronze Age males, I6470 and I3997, had DNA sequences overlapping R1b-Z195
(R1b1a1a2a1a2a1), with I6470 being negative and I3997 positive. Eleven Bronze Age
males had DNA sequences overlapping R1b-Z225 (R1b1a1a2a1a2a5), with only
VAD001 being positive for the mutation (one Iron Age male, I3320, is also positive for
this mutation). We thus detect three Bronze Age males who belonged to DF27 (154, 155),
confirming its presence in Bronze Age Iberia. The other Iberian Bronze Age males could
belong to DF27 as well, but the extremely low recovery rate of this SNP in our dataset
prevented us to study its true distribution. All the Iberian Bronze Age males with
overlapping sequences at R1b-L21 were negative for this mutation. Therefore, we can
rule out Britain as a plausible proximate origin since contemporaneous British males are
derived for the L21 subtype."

"Finding a Bell Beaker-related group as a plausible source for the introduction of steppe
ancestry into Iberia is consistent with the fact that some of the individuals in the Iberia_CA_Stp
group were excavated in BellBeaker associated contexts (9). Models with Iberia_CA and other Bell
Beaker groups such as France_Beaker (P-value=7.31E-06), Netherlands_Beaker
(P-value=1.03E-03) and England_Beaker (P-value=4.86E-02) failed, probably because they
have slightly higher proportions of steppe ancestry than the true source population. We can also discard
Beaker complex individuals from the island of Britain as a plausible directly source for
the steppe ancestry in Iberia because all the analyzed males with enough resolution in this
group are derived for R1b-L21, a SNP for which Iberian males are ancestral."

Which exactly are the Celtiberian samples? I only see Iron Age samples from non-indo european areas (mediterranean coast):



I would except Celtiberian samples to be from the celtiberian region:
