The recent data on ancient DNA from Iberia published by Olalde et al. (2019) was interesting for many different reasons, but I still have the impression that the authors – and consequently many readers – focused on not-so-relevant information about more recent population movements, or even highlighted the least interesting details related to historical events.
I have already written about the relevance of its findings for the Indo-European question in an initial assessment, then in a more detailed post about its consequences, then about the arrival of Celtic languages with hg. R1b-M167, and later in combination with … Read the rest “North-West Indo-Europeans of Iberian Beaker descent and haplogroup R1b-P312”
The nature of the prehistoric languages of the British Isles is particularly difficult to address: because of the lack of ancient data from certain territories; because of the traditional interpretation of Old European names simply as “Celtic”; and because Vennemann’s re-labelling of the Old European hydrotoponymy as non-Indo-European has helped distract the focus away from the real non-Indo-European substrate on the islands.
Alteuropäisch and Celtic
An interesting summary of hydronymy in the British Isles was already offered long ago, in British and European River-Names, by Kitson, Transactions of the Philological Society (1996) 94(2):73-118. In it, he discusses, among others:… Read the rest “European hydrotoponymy (VI): the British Isles and non-Indo-Europeans”
The final paper on Indo-Iranian peoples, by Narasimhan and Patterson (see preprint), is soon to be published, according to the first author’s Twitter account.
One of the interesting details of the development of Bronze Age Iberian ethnolinguistic landscape was the making of Proto-Iberian and Proto-Basque communities, which we already knew were going to show R1b-P312 lineages, a haplogroup clearly associated during the Bell Beaker period with expanding North-West Indo-Europeans:
From the Bronze Age (~2200–900 BCE), we increase the available dataset from 7 to 60 individuals and show how ancestry from the Pontic-Caspian steppe (Steppe ancestry) appeared throughout Iberia

As you can see from my interest in the recently published Olalde et al. (2019) Iberia paper, once you accept that East Bell Beakers expanded North-West Indo-European, the most important question becomes how did its known dialects spread to their known historic areas.
We already had a good idea about the expansion of Celts, based on proto-historical accounts, fragmentary languages, and linguistic guesstimates, but the connection of Celtic with either Urnfield or slightly later Hallstatt/La Tène was always blurred, due to the lack of precise data on population movements.
The latest paper on Iberia is interesting for many … Read the rest “Haplogroup R1b-M167/SRY2627 linked to Celts expanding with the Urnfield culture”
I had some more time to read the paper by Valdiosera et al. (2018) and its supplementary material.
One of the main issues since the publication of Olalde et al. (2018) (and its hundreds of Bell Beaker samples) was the lack of a clear Y-DNA R1b-DF27 subclades among East Bell Beaker migrants, which left us wondering when the subclade entered the Iberian Peninsula, since it could have (theoretically) happened from the Chalcolithic to the Iron Age.
My prediction was that this lineage found today widespread among the Iberian population crossed the Pyrenees quite early, during the Chalcolithic, with … Read the rest “First Iberian R1b-DF27 sample, probably from incoming East Bell Beakers”

1. The Irish DNA Atlas: Revealing Fine-Scale Population Structure and History within Ireland, by Gilbert et al., in Scientific Reports (2017).
The extent of population structure within Ireland is largely unknown, as is the impact of historical migrations. Here we illustrate fine-scale genetic structure across Ireland that follows geographic boundaries and present evidence of admixture events into Ireland. Utilising the ‘Irish DNA Atlas’, a cohort (n = 194) of Irish individuals with four generations of ancestry linked to specific regions in Ireland, in combination with 2,039 individuals from the
