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”
As I said 6 months ago, 2019 is a tough year to write a blog, because this was going to be a complex regional election year and therefore a time of political promises, hence tenure offers too. Now the preliminary offers have been made, elections have passed, but the timing has slightly shifted toward 2020. So I may have the time, but not really any benefit of dedicating too much effort to the blog, and a lot of potential benefit of dedicating any time to evaluable scientific work.
On the other hand, I saw some potential benefit for … Read the rest “A Song of Sheep and Horses, revised edition, now available as printed books”
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”
New paper (behind paywall), The genomic history of the Iberian Peninsula over the past 8000 years, by Olalde et al. Science (2019).
NOTE. Access to article from Reich Lab: main paper and supplementary materials.
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
