Recent paper (behind paywall) Population genomics of the Viking world, by Margaryan et al. Nature (2020), containing almost exactly the same information as its bioRxiv preprint.
I have used Y-SNP inferences recently reported by FTDNA (see below) to update my Ancient DNA Dataset and the ArcGIS Online Map, and also to examine the chronological and geographical evolution of Y-DNA (alone and in combination with ancestry).
Sections of this post:
- Iron Age to Medieval Y-DNA
- Iron Age to Medieval Ancestry
- Iron Age to Medieval Y-DNA + Ancestry
- FTDNA’s big public debut

Informal report by Bulgarian archaeologist Svetoslav Stamov in 7/8 TV, from data collected by the Reich Lab for their future paper on South-Eastern Europe.
As can be seen from the TV captions below, this is the earliest R1b-P310 from Yamnaya or Yamnaya-related individuals in Early Bronze Age contexts from Bulgaria. In fact, its appearance together with a R1b-Z2103 lineage (and another undefined R1b-M269) shows once again that the earliest R1b-L23 bottlenecks were associated with Proto-Indo-Europeans.
Lacking a precise periodization, location, or proper cultural context in the spreadsheet, it is impossible to know whether they belong to Khvalynsk-related cultures … Read the rest “West Yamnaya settlers like Early Bell Beakers: R1b-P310 and R1b-Z2103”
Recently published paper Genomic Data from an Ancient European Battlefield Indicates On-Going Strong Selection on a Genomic Region Associated with Lactase Persistence Over the Last 3,000 Years, by Burger et al., submitted to Current Biology, available at CellPress SneakPeek.
Interesting excerpts (emphasis mine):
Tollense sample shows no structure
Multiple lines of evidence point to little or no genetic structure in the population from which the Tollense individuals were sampled. First, all individuals fall within the range of Central and northern European variation when projected onto a principle component analysis (PCA) trained on modern samples and their spread matches that

Recent paper A dynastic elite in monumental Neolithic society, by Cassidy et al. Nature (2020) 582:384–388.
Interesting excerpts (emphasis mine):
We sampled remains from all of the major Irish Neolithic funerary traditions: court tombs, portal tombs, passage tombs, Linkardstown-type burials and natural sites. Within this dataset, the earliest Neolithic human remains from the island—interred at Poulnabrone portal tomb14—are of majority ‘Early_Farmer’ ancestry (as defined by ADMIXTURE modelling), and show no evidence of inbreeding, which implies that, from the very onset, agriculture was accompanied by large-scale maritime colonization. Our ADMIXTURE and ChromoPainter analyses do not distinguish between

I have compiled for two years now the reported Y-DNA and mtDNA haplogroups of ancient DNA samples published, including also SNPs from analysis of the BAM files by hobbyists.
Here is a video with a timeline of the evolution of Indo-European speakers, according to what is known today about reconstructed languages, prehistoric cultures and ancient DNA:
NOTE. The video is best viewed in HD 1080p (1920×1080) with a display that allows for this or greater video quality, and a screen big enough to see haplogroup symbols, i.e. tablet or greater. The YouTube link is here. The … Read the rest “The expansion of Indo-Europeans in Y-chromosome haplogroups”
New paper (behind paywall) Ancient Rome: A genetic crossroads of Europe and the Mediterranean, by Antonio et al. Science (2019).
The paper offers a lot of interesting data concerning the Roman Empire and more recent periods, but I will focus on Italic and Etruscan origins.
NOTE. I have updated prehistoric maps with Y-DNA and mtDNA data, and also the PCA of ancient Eurasian samples by period including the recently published samples, now with added sample names to find them easily by searching the PDFs.

Open access Population genomics of the Viking world, by Margaryan et al. bioRxiv (2019), with a huge new sampling from the Viking Age.
#EDIT (16 SEP 2020): The paper has been published in Nature.
Interesting excerpts (emphasis mine, modified for clarity):
To understand the genetic structure and influence of the Viking expansion, we sequenced the genomes of 442 ancient humans from across Europe and Greenland ranging from the Bronze Age (c. 2400 BC) to the early Modern period (c. 1600 CE), with particular emphasis on the Viking Age. We find that the period preceding the Viking Age was

A recently published abstract for an upcoming chapter about Early Slavs shows the generalized view among modern researchers that Common Slavs did not spread explosively from the east, an idea proper of 19th-century Romantic views about ancestral tribes of pure peoples showing continuity since time immemorial.
Migrations and language shifts as components of the Slavic spread, by Lindstedt and Salmela, In: Language contact and the early Slavs, Eds. Tomáš Klír, Vít Boček, Universitätsverlag Winter (2019):
The rapid spread of the Proto-Slavic language in the second half of the first millennium CE was long explained by the … Read the rest ““Dinaric I2a” and the expansion of Common Slavs from East-Central Europe”
This is mainly a reread of from Book Two: A Game of Clans of the series A Song of Sheep and Horses: chapters iii.5. Early Indo-Europeans and Uralians, iv.3. Early Uralians, v.6. Late Uralians and vi.3. Disintegrating Uralians.
While the true source of R1a-M417 – the main haplogroup eventually associated with Corded Ware, and thus Uralic speakers – is still not known with precision, due to the lack of R1a-M198 in ancient samples, we already know that the Pontic-Caspian steppes were probably not it.
We have many samples from the north Pontic area since … Read the rest “ASoSaH Reread (II): Y-DNA haplogroups among Uralians (apart from R1a-M417)”
