Increased mobility in the Nordic Late Neolithic/Bronze Age

Open access Mobility patterns in inland southwestern Sweden during the Neolithic and Early Bronze Age, by Blank, Sjögren, Knipper, et al. Archaeol. Anthropol. Sci. 13, 64 (2021).

NOTE. For a full archaeological description of the area of study, refer to the related paper Old bones or early graves? Megalithic burial sequences in southern Sweden based on 14C datings, by Blank, Sjögren, & Storå, Archaeol. Anthropol. Sci. 12, 89 (2020).

Interesting excerpts (emphasis mine):

The sampling from megalithic graves shows a chronological gap of at least 400 years (2600–2200 cal BC), when no megalithic graves were constructed or used

Earliest (and basal) haplogroup N-L1026, from East Siberia

This is an update to the data from Human population dynamics and Yersinia pestis in ancient northeast Asia, by Kılınç et al. Science Advances (2021).

Files have been released, and some of them are huge, so it might take me some time to analyze them all and include specific subclades in the Ancient DNA Dataset.

For the moment, the sample I highlighted in the previous post, kra001 (2336-2135 calBCE), mtDNA C4b1, from burial Nº1 of Nefteprovod-2, is of very good quality, and it would not be surprising if it made its way to YFull’s tree. It can be … Read the rest “Earliest (and basal) haplogroup N-L1026, from East Siberia”

“Local” Tollense Valley warriors linked to Germanic peoples

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

R1a-Z93-rich Classical CWC-like Fatyanovo replaced Volosovo

Open access Genetic ancestry changes in Stone to Bronze Age transition in the East European plain, by Saag et al. bioRxiv (2020).

Interesting excerpts (emphasis mine):

Y-DNA chromosome haplogroup

(…) the Bronze Age Fatyanovo Culture individuals [] maternal (subclades of mtDNA hg U5, U4, U2e, H, T, W, J, K, I and N1a) and paternal (chrY hg R1a-M417) lineages were ones characteristic of CWC individuals elsewhere in Europe. Interestingly, in all individuals for which the chrY hg could be determined with more depth (n=6), it was R1a2-Z93, a lineage now spread in Central and South Asia, rather than the

Early arrival of Steppe ancestry in Switzerland

Open access paper Ancient genomes reveal social and genetic structure of Late Neolithic Switzerland by Furtwängler et al. Nat. Commun. (2020).

Interesting excerpts (emphasis mine):

The ancient individuals from this study originate from 13 Neolithic and Early Bronze Age sites in Switzerland, Southern Germany, and the Alsace region in France. All samples taken from the individuals were radiocarbon dated.

The arrival of Steppe ancestry

Two distinct clusters can be identified and were also confirmed by ADMIXTURE analysis, one consisting of individuals dating to 4770–2500 calBCE, and one comprising individuals dating to 2900–1750 calBCE. The oldest individuals from the sites of

European hydrotoponymy (VII): Celtic From the West or the East?

Recent paper (behind paywall) An Alternative to ‘Celtic from the East’ and ‘Celtic from the West’, by Patrick Sims-Williams Camb. Archaeol. J (2020) First View.

NOTE. For those who don’t have access to it, you can check other recent similar papers by the same author, like Sims-Williams (2009, 2012, 2017).

Interesting excerpts (emphasis mine):

Celtic origins

(…) there have been three main stages of scholarship: (1) the Celts are identified with the Hallstatt and La Tène ‘cultures’ of the first millennium BC; (2) then the discovery of contemporary Celtic language inscriptions (Lepontic and Celtiberian) in the ‘wrong’ areas

Fully Steppe-like Proto-Corded Ware Late Trypillians

The genotypes from Human auditory ossicles as an alternative optimal source of ancient DNA, by Sirak et al. Genome Res. (2020), have been finally published by the Reich Lab, so we can get a sneak peek into what’s coming in future papers about the origins of R1a-rich Proto-Corded Ware and R1b-rich Italo-Venetic peoples.

NOTE. To avoid adding potential errors, I have merged the Reich Lab’s Curated Dataset (v. 42.4, March 1 2020) with these new samples before performing the qpAdm analyses. If you find something different with your files, you should probably check out this simple setting first. … Read the rest “Fully Steppe-like Proto-Corded Ware Late Trypillians”

Visualizing phylogenetic trees of ancient DNA in a map

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 expansion of Indo-Europeans in Y-chromosome haplogroups

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.

Y-DNA timeline

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”
