2 BA Iberians

Two Bronze Age Iberians look like Eastern France Beakers.  One is DF27. 

Epi-Cardial is genetically Cardial + the letters Epi. 

The Basques look close to LN/CHL

Some other interesting stuff.  See Bernard'blog in sidebar

Kin in Kornice (PAP)

Science in Poland has this "Unusual journey of culture in prehistoric Europe" on a Beaker cemetery in Kornice, Poland.

You learn a little from everywhere...
"Our samples from several sites in Lower and Upper Silesia were analysed in the Reich Laboratory of David Reich from the Department of Genetics of Harvard Medical School in Boston by the team led by David Reich and Iñigo Olalde" - explains Dr. Furmanek in the materials sent by the University of Wroclaw. - "The largest number of samples comes from the extremely interesting Bell-Beaker culture cemetery in Kornice, in the commune of Pietrowice Wielkie in Silesia. With regard to these burials, we have also obtained interesting information about family relationships between some of the dead. We have identified a father and two of his children - a son and a daughter".
It'd be interesting to see how much admixture existed between the father and his wife.

All About Iberia (Goncalves, 2017)

This is a large 2017 compendium on Iberian Bell Beakers (linked below) with a lot of attention on Portugal and Southern Spain.  The leading archaeologists from the corners of the peninsula presented their cases knowing the early results of the Olalde et al, 2017 pre-print.

Iberia is not that simple for beakers and you get a sense of that reading from the authors presenting here.  It's hard to interpret Iberian Beakers as a coherent group when they are so inconsistent from site to site, region to region.  But it's important to remember the size of the peninsula when overlayed on a map of Europe.  It's a huge area with great human numbers of diverse backgrounds in ancient times.  So rather than saying there is an Iberian Beaker, there's probably several different Beaker nations or traveling groups that were in a constant state of flux and having slightly different cultural backgrounds. 

One of the Portuguese Olalde samples was a 'Beaker without Bell Beakers' as presented by Zilhao.  That's a complicated situation when the individual is only classified as Beaker by a scrap of gold, two buttons and turns up genomically Neolithic (not saying that's wrong).  But identity isn't always as simple as the Amesbury Archer.

And then Goncalves seems to suggests in the introduction that acacia decoration is found outside of Iberia everywhere in a very low degree which would be interesting. (again the translation is garbled, I may have misinterpreted this)

Epigentic traits of Bohemian Beakers (Czarnetzki, 1976)

In 1969 Alfred Czarnetzki examined a collection of ancient skulls spanning the Late Neolithic, Beaker Period and the Aunjetitz (Unetice) Culture in Bohemia, Czechoslovakia.  His analysis of early epigenetic and non-metric traits got a supporting boost from the recent Olalde paper.

Although he and his colleagues had examined numerous traits in this set, in the article he chose to focus on persistent metopism for discussion.  Commonly believed to be an epigenetic trait, he discusses the frequencies of males and females among these remains and makes some comments about gender-based mobility, ethnic intermingling and population continuity.

Persistent metopism is different from metopic craniosynostosis in that the rather than the premature fusion of the plates, the fibrous sutures between plates persist through adulthood creating a sort of soft line.

Czarnetzki found (here free to read at JSTOR after registering) what appeared to be a clear break between the Late Neolithic and the Bell Beaker where the incidence in the females is reduced in half.  The frequency between Bell Beaker and Unetice is similar, which is viewed as population continuity.  Only looking at this one trait, he proposed that during the Bell Beaker period there had being a influx of immigrants that was male-biased into the local population.  During the Beaker period he sees a leveling of sorts with male immigrants and local women, this in turn is expressed in new frequencies during Unetice.

Metopism does not appear to be correlated with common head shapes and it's probably not useful other than looking at local populations within a short period.  But older studies like this deserve a victory lap for being a vanguard of new anthropological data and for being right at the wrong time.

If I don't flunk out of this, I'll try to do some modeling of different Beaker populations within the coming days and weeks.  If you have anything of your own, please post in the comments section.  There's enough genomes now to start making some real use of what's available.  More to follow.

Frog Pose or Yamna Repose?

Although the male in grave 3 is not included in the current Olalde paper, his burial pose is more interesting now with the revelation that one of his apparent kin (I4253) is Z2103.  These residents were from a small cemetery in Samborzec, Little Poland and genetically tested in "The Beaker Phenomenon and the Genomic Transformation of Northwestern Europe"

In a paper entitled "Yamnaya Groups and Tumuli West of the Black Sea", Volker Heyd made this comment regarding the orientation of bodies in the Western Yamnaya:
"The position of the body in the [Yamna] grave pit is typically supine with the flexed legs...Flexed legs are often still upright, even after thousands of years in the graves, but may have also fallen to one side due to decomposition of the body tissues.  Also, the so-called frog-position of the legs might be due to this process of decay."
Male Archer looking East.  Samborzec, stanowisko 1, grave 3 (Makarowicz)
I've discussed frog-burials in this post "The Samborzec Sage" and my interpretation was that these could have been devaraja poses of high status males that had relaxed within the container.  But Heyd's comment makes more sense after looking again at grave 3's clearly supine position. 

The legs of grave 3 may have originally looked like this, which is how Yamna people were buried.

So now the fun part.  What does this mean?  Z2103 is now in two Beaker graves I2787, I7044 from Szigetszentmiklos and I4253 from Samborzec.  A man at Samborzec appears to have been buried with a mixture of Beaker and Yamnaya rites.  But what does the phylogeny mean in light of this?

One way to look at this is that there is a clear sign of a founder effect heading West.  Looking strictly at the phylogeny of R1b, and not taking anything else into consideration, this of course makes a lot of sense.  That solves it for a lot of people.  But extrapolating geo-phylogeny on an archaeological culture can be a problem when the two are in apparent disagreement.

Another way to look at it (until Western kurgans prove or disprove the presence of L51/P312) is that in the highly heterogeneous border outpost of the Csepel populations (and by extension the closely related Samborzec community), Bell Beakers and Yamnaya, confusingly, actually mixed to a small and unimportant degree.

Within these old Beaker cemeteries of Békásmegyer, Budakalasz, Szigetszentmiklós, Bell Beakers appear as a minority that increases but it is clear that there are different peoples mixing at these sites and that mixing is a cultural trajectory away from Bell Beaker.

I2787 at Szigetszentmiklos could be a red herring or it could provide a connection. While it's obvious Beaker is paternally related to Z2103 and shares a similar ideaology, and while a bunch of scenarios and chronologies are possible, drawing straight arrows from one to the other is an over-simplification or wrong.

But in any case, this one grave is an interesting one with mixed traits.
