Embracing the Bell Beakers

[Rodoorn]

When @Stevens still had no exclusive focus on his own Y-DNA with regard to the origins of the Bell Beakers he posted some very interesting things, worth quoting:

"
It seems to me pretty clear that Beaker began as an offshoot of Single Grave Corded Ware in the Netherlands and NW Germany.

Here's some of what Davidski wrote in his Eurogenes Blog back in 2019 (notice that this predates both Linderholm et al and Papac et al):

Quote:
- the Dutch Beakers are unlikely to be the result of a recent migration from afar into what is now The Netherlands and surrounds, but rather the descendants, by and large, of the earlier local Single Grave (and thus Corded Ware) populations


- the R1b-P312 lineages in the Dutch and British Beakers probably derive from Single Grave R1b-P312, which suggests that R1b-P312 was common among some clans within the Corded Ware culture

- the spread of most of the Yamnaya-related or steppe ancestry and quintessential Beaker physique across the Beaker world and into Western Europe can probably be blamed on the massive expansions of Beakers from what is now The Netherlands and surrounds (ie. the Lower Rhine region)

Single Grave > Bell Beakers

Notice also that it is extremely unlikely that Beaker began in Iberia, since ancient Beaker remains outside Iberia lack Iberian Neolithic DNA. The following is from the 2018 Olalde et al paper, "The Beaker phenomenon and the genomic transformation of northwest Europe", pages 3-4:

Quote:
Conversely, the Neolithic related ancestry in Beaker-complex-associated individuals outside of Iberia was most closely related to central and northern European Neolithic populations with relatively high hunter-gatherer admixture (for example, Poland_LN, P = 0.18 and Sweden_MN, P = 0.25), and we could significantly exclude Iberian sources (P < 0.0104) (Fig. 2c). These results support mostly different origins for Beaker-complex associated individuals, with no discernible Iberia-related ancestry outside of Iberia.


The following is from page 470 of "Corded Ware from East to West", by Janusz Czebreszuk, pages 467-475 in the book, Ancient Europe 8000 B.C.–A.D. 1000: Encyclopedia of the Barbarian World (edited by Peter Bogucki and Pam Crabtree; New York: Charles Scribner's Sons, 2004):

Quote:
Protruding Foot Beaker Culture. The Protruding Foot Beaker culture is the best-known part of the Corded Ware story. It is found along the Lower Rhine, in a key place for long-range contacts between the British Isles and the Alpine area, as well as along the Atlantic shore to the Baltic Sea. There exists an accurate typology of its basic object: the beaker. Much is known about the culture’s settlements. To assure proper living conditions (that is, a dry place on the wet landscape of the Rhine Delta), permanent settlements were built on artificial platforms consisting of layers of shells, organic remains, and clay. The dwellings were rectangular huts of post construction. The funeral rites were characterized by the presence of flat graves as well as barrows, in which according to the Corded Ware custom, only one individual was laid. The Protruding Foot Beaker culture is also important because in 1955 Johannes D. van der Waals and Willem Glasbergen were able to demonstrate stylistic links that its beakers shared with the Bell Beakers. This became a basis for one of the main models for the genesis of the Bell Beakers called the “Dutch Model.”

From page 16 of the 1955 paper by Van Der Waals and Glasbergen, "Beaker Types and their Distribution in the Netherlands":

Quote:
Where is the origin of the Dutch Beakers with protruding foot to be sought? Sangmeister has discussed the distribution of this Beaker class - his Westdeutsche Becherguppe - in Western Germany and the Netherlands. There is undoubtedly a close affinity to the Central German Schnurkeramik [Corded Ware] culture, and it can be assumed that this latter culture represents the origin of sub-group Ia of the Dutch Beakers with protruding foot."

A few remarks. First of all I think the heartland discussion is fruitless. Because there was no nodus, no one size fits all Bell Beaker phenomenon. I'm convinced that we have think in a kind of diversity when it comes to the Bell Beakers and also in networks, that really functioned on a pan Central and West European scale. So no Dutch or of Spanish model!

No one way streets (but a network). And Olalde et al (2018) have clearly shown that in genetic sense the Northern Beakers flew to the SW of Europa. It would be false to think that there were only N>S upstream, it must have been also S>N although it's clear that it must have been to a much lesser extent the case.

Mr Stevens accused me of being a "ethno-nationalist" (he later on wisely withdrew). Well if I was a ethno nationalist I would fully embrace the Dutch model, with the NE Dutch/ NW Germany BB aka Protruding Foot Beaker at it's core. Even more when I'm most probably (partly) derived from this "ethnicity". But I don't.

When I look at the genetics I think especially the Beaker of Northern Europe share the same kind of initial sources but nevertheless are differentiated. Even on the tiny Dutch scale there is a difference between Central Dutch Beakers and NE Dutch Beakers.

From Lanting 2007/8 drawing by Mitch, with red star the so called Oostwoud= Central Dutch BB samples:



I don't recall the discussion about BB Lech WEHR_1192 sample, the result is imo clear it is a good proxy for the NE Dutch/NW Germany BB (and even more he was most likely derived from this population)

So I guess we all got differentiated groups through Central and West Europe, these groups as like the Central Dutch BB or the NE Dutch BB were tight knit, but in between them it was loose fit, their share was most based on some same source populations.

Or in the wise words of member @Dewsloth based on IBD:
"I don't see anything in the IBD that points to a substantial contemporary link between WEHR_1192 and any Dutch Beakers.  Their links seem to be mostly shared ancestry from more ancient samples."

Not being a Dutch model "ethno nationalist" this doesn't mean that I disregard them. On the contrary I consider myself although very very on distance still standing on their shoulders...

In this respect I'm inclined to follow the "Clarke model" in which there was a spread to for example the Isles from differentiated BB groups. The NE Dutch/ NW Germany groups had according to him these primal targets:

"These folk, with their strong non-beaker background, apparently crossed the North Sea in a series of small bands somewhere around 1700 B.C. or slightly later.
The settlers clustered in three foci based on the North Sea Coast: - around the Moray Firth, in the Border Counties and on the Yorkshire Wolds."

So a "minimalistic Dutch model"?

[Mitchell-Atkins]

Here is a list of genetic distances (1-ibs, where ibs designates the proportion of shared alleles) calculated with PLINK, between finnmum (Rodoorn's mother) and some individuals. All genomes are imputed, either by me or by Allentoft. I strongly warn against the use of G25 pseudo-distances (Euclidean distances calculated on the components of a PCA, no one uses that as a genetic distance in real life). Since Rodoorn asked me for my opinion via PM, which I have been careful not to do until now, I will allow myself to summarize it in one sentence. All this story actually derives from an illusion resulting from the adventurous interpretation of the results given by an unsuitable tool. But this is obviously just my opinion.

[Anglesqueville]

^^ Mitchell-Atkins: Real genetic "distances" computed with the alleles (as I explained, 1 - proportion of shared alleles), nothing to see with G25 Euclidean distances. All are distances from the individual to Rodoorn's mother. All genomes are around 900.000 SNPs. For the experts, I did the same thing with LD-pruning, maf-filtering, and all results were basically the same. In short, Rodoorn's mum is likely autosomally much closer to individuals from Denmark's Bronze and Iron ages than to Beakers, which I believe is expected.

Thanks again!

Ok this clears something and I share this conclusion of course. The impact of the Germanic influx was most recent and the biggest.

Nevertheless from a very big time leap namely about 2600 years before the Germanic influx BB Lech is on front....a difference with number 1 in distance 0,05 with such a time gap...

Makes Lech even more likely a NE Dutch BB!

[Anglesqueville]

For all: don't care about the suffix "_A", as in "NEO857_A". It's a personal code to differentiate the original genomes from their post-imputations (by Allentoft) version.

You must understand that by definition a 1-ibs "distance" is between 0 and 1 (0 for two identical genomes, 1 for proportion of shared alleles=0). It's no Euclidean thing. On such a scale a difference of 0.05 is far from negligible. If I wanted to prove something about Lech, that's certainly not how I would go about it. But since I don't have a precise idea about him, the question is a bit rhetorical.

I'm confused by this conclusion.  

There's an obvious gap between your mother's distance to Denmark Bronze Age samples and the WEHR 1192 & Oostwold samples.

Danish Bronze Age samples range from 0.247-0260, then a gap to WEHR 1192 & Oostwold samples 0.300 to 0.314  

There is very little difference between your mother's distance to WEHR 1192 and the Holland BB and MBA samples (004284-.014141)

Yes of course. No single prove for whatsoever. Just the clean observation that from the BB at stake Lech is the relative nearest. And compared to the Danish samples it is a chunk older.

(For the rest you have seen it well with little expectations about SGC or NE Dutch BB samples in the future Lech is some sort of straw

[Mitchell-Atkins]

Anglesqueville,

Not sure how labor intensive this is, but it may be informative to run Plink calculation on WEHR_1192SkA Lech to relevant ancient samples. Is he closer to these Oostwold BB & MBA samples or to the Danish Bronze Age samples?

Or Davidski sees that WEHR_1192 plots close to the Holland BB and Holland is on the North Sea coast.

Indeed but from the BB the nearest. What as we look sec were it was found (Lech is very on distance from Drenthe!) not to be expected. So it's my good guess is that he could well be from the NE Dutch/ NW Germany area which is in the prospected range of Davidski: "from potentially as far away as the North Sea coast". Potential fulfilled?

Or Davidski sees that WEHR_1192 plots close to the Holland BB and Holland is on the North Sea coast.

I don't know if I'm that into Davidski watching  

My mother as "rootstocked" NE Dutch is closer to Wehr than to Oostwoud (although foto finish). That is enough.

And further I think I can only underline Angles "Rodoorn's mum is likely autosomally much closer to individuals from Denmark's Bronze and Iron ages than to Beakers". 

I would personally prefer- but a bit matter of words- Rodoorn's mum is likely automal most of Danish Bronze Age and Iron Age but some BB NE Dutch shimmers through.

And as a historian set on a time line, first we got the PFB/ NE Dutch Beakers, mostly due to an impact of SGC. And much later about 400 AD followed by an influx by the Anglo-Saxons.

And in fact I could go even deeper but then it gets much more tricky. Because there was an interaction between SGC from the North Dutch area unto Jutland. And not to mention the Ertebølle HG (with some neolithic package) expansion towards the West aka West TRB. This all affected the BB NE Dutch as the Bronze Age/Iron Age Danes. Much interaction. So not easy to disentangle. So can't draw any conclusion about that.
