Yesterday the Eaton Lab at Columbia University announced on Twitter a nifty little tool by Carlos Alonso Maya-Lastra called TreeToM, which accepts Newick trees and CSV latitude/longitude data to explore phylogeny and geography interactively, with no coding required.
I thought it could complement nicely my All Ancient DNA Dataset, particularly for those newly described SNPs (FTDNA private variants, etc.) that have not been incorporated yet into SNP Tracker.
Here are two examples with snippets to copy&paste to the appropriate boxes in TreeToM. Feel free to add others in the comments:… Read the rest “Visualizing phylogenetic trees of ancient DNA in a map”
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 first layer in hydrotoponymy of Iberia is clearly Indo-European, in territories that were occupied by Indo-Europeans when Romans arrived, but also in most of those occupied by non-Indo-Europeans.
Among Indo-European peoples, the traditional paradigm – carried around in Wikipedia-like texts until our days – has been to classify their languages as “Pre-Celtic” despite the non-Celtic phonetics (especially the initial -p-), because the same toponyms appear in areas occupied by Celts (e.g. Parisii, Pictones, Pelendones, Palantia); or – even worse – just as “Celtic”, because of the famous -briga and related components. This was evidently not tenable at the … Read the rest “European hydrotoponymy (II): Basques and Iberians after Lusitanians and “Ligurians””
These first two posts on Old European hydro-toponymy contain excerpts mainly from Indoeuropeos, iberos, vascos y sus parientes, by Francisco Villar, Universidad de Salmanca (2014), but also from materials of Lenguas, genes y culturas en la Prehistoria de Europa y Asia suroccidental, by Villar et al. Universidad de Salamanca (2007). I can’t recommend both books hardly enough for anyone interested in the history of Pre-Roman peoples in Iberia and Western Europe.
NOTE. Both books also contain detailed information on hydrotoponymy of other regions, like Northern Europe, the Aegean and the Middle East, with some information about Asia, apart … Read the rest “European hydrotoponymy (I): Old European substrate and its relative chronology”
New preprint Late Upper Palaeolithic hunter-gatherers in the Central Mediterranean: new archaeological and genetic data from the Late Epigravettian burial Oriente C (Favignana, Sicily), by Catalano et al. bioRxiv (2019).
Interesting excerpts (emphasis mine):
Grotta d’Oriente is a small coastal cave located on the island of Favignana, the largest (~20 km2) of a group of small islands forming the Egadi Archipelago, ~5 km from the NW coast of Sicily.
The Oriente C funeral pit opens in the lower portion of layer 7, specifically sublayer 7D. Two radiocarbon dates on charcoal from the sublayers 7D (12149±65 uncal. BP) and 7E,

Open access Tracking Five Millennia of Horse Management with Extensive Ancient Genome Time Series, by Fages et al. Cell (2019).
Interesting excerpts (emphasis mine):
The earliest archaeological evidence of horse milking, harnessing, and corralling is found in the ∼5,500-year-old Botai culture of Central Asian steppes (Gaunitz et al., 2018, Outram et al., 2009; see Kosintsev and Kuznetsov, 2013 for discussion). Botai-like horses are, however, not the direct ancestors of modern domesticates but of Przewalski’s horses (Gaunitz et al., 2018). The genetic origin of modern domesticates thus remains contentious, with suggested candidates in the Pontic-Caspian steppes (Anthony, 2007), Anatolia (Arbuckle,

New preprint Population history from the Neolithic to present on the Mediterranean island of Sardinia: An ancient DNA perspective, by Marcus et al. bioRxiv (2019)
Interesting excerpts (emphasis mine, edited for clarity):
On the high frequency of R1b-V88
Our genome-wide data allowed us to assign Y haplogroups for 25 ancient Sardinian individuals. More than half of them consist of R1b-V88 (n=10) or I2-M223 (n=7).
Francalacci et al. (2013) identified three major Sardinia-specific founder clades based on present-day variation within the haplogroups I2-M26, G2-L91 and R1b-V88, and here we found each of those broader haplogroups in at least one

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
