Unleash the power: Global 25 test drive thread

Ancestry modeling enthusiasts, feel free to do your best (or worst) with these datasheets and share the output, whatever it might be, in the comments below:

The Global 25 is a more powerful version of the Global 10 ancestry analysis (see here). If all goes well in

Mitogenomes from the Iron Age South Baltic (Stolarek et al. 2018)

Over at Scientific Reports at this LINK. And yes, full genomes of many of the samples are on the way. Emphasis is mine:

Abstract: Despite the increase in our knowledge about the factors that shaped the genetic structure of the human population in Europe, the demographic processes that occurred during and after the Early Bronze Age (EBA) in Central-East Europe remain unclear. To fill the gap, we

Early Baltic Corded Ware form a genetic clade with Yamnaya, but...

This is what Mittnik et al. 2018 say about a couple of their Corded Ware, or Baltic Late Neolithic (Baltic_LN), samples from what is now Lithuania:

Computing D-statistics for each individual of the form D(Baltic LN, Yamnaya; X, Mbuti), we find that the two individuals from the early phase of the LN (Plinkaigalis242 and Gyvakarai1, dating to ca. 3200–2600 calBCE) form a clade with Yamnaya (

Indian smoke and mirrors

On January 4 this year Hindi newspaper Dainik Jagran published a so called special feature on Indo-European languages. In fact, the article claimed to be giving its readers a sneak peak at the results from the upcoming and much anticipated archaeogenetics paper on the northern Indian Harappan site of Rakhigarhi.

I knew about this article when it first came out, because it was mentioned in

Paleoeuropeoid (steppe herder) infiltration into South Central Asia during the Bronze Age (Dubova et al. 2016)

Update 31/03/2018: Check out this awesome new preprint at bioRxiv: The Genomic Formation of South and Central Asia (Narasimhan et al. 2018)

...

I don't usually take cranial studies very seriously, mostly because they have a history of being way out of the ballpark. However, Interaction between Steppe and Agricultural Tribes during the Bronze Age: Morphological Aspects by Dubova et al. 2016 is,

mtDNAwiki on "Steppe folk" mtDNA and Indo-Iranian origins

Fascinating stuff from Samuel at mtDNAwiki. Emphasis is mine:

Steppe folk were people who resided in what are today Southern Russia and Eastern Ukraine between 6,000 and 4,000 years ago. They were very different from the Anatolian farmers I discussed earlier.

Ancient DNA shows that, between 3000 and 2000 BC, Steppe folk migrated en masse into Northern Europe, Central Asia and Siberia. Shortly

Unadmixed Basal Eurasians lived throughout the Near East ~45-15 KYA?

Below is a map from a recent review paper at Trends in Genetics by Melinda A. Yang and Qiaomei Fu titled Insights into Modern Human Prehistory Using Ancient Genomes.



It's somewhat speculative and an abstract of geographic realities (note that the ancient "Karelia" population is placed several thousand miles east of Karelia, in Northern Asia as opposed to Northeastern Europe). Nevertheless, the
