...the new study encompasses data from nearly 300 ancient individuals and focuses specifically on the Copper to Bronze Age transition...
The genomic data reveals some of the processes underlying this genetic shift. While the bulk of the genome shows that Bronze Age individuals are a mix of local Iberian Chalcolithic ancestry and a smaller part of incoming ancestry from the European mainland, the paternally inherited Y chromosome lineages show a complete turnover, linked to the movement of steppe-related ancestry that is also visible in other parts of Europe...
"We also found signals of ancestry that we traced to the central and eastern Mediterranean and western Asia. We cannot say exactly whether these influences arrived at the same time as the steppe-related ancestry, but it shows that it formed an integrative part of the rising El Argar societies, attesting to continued contacts to these regions," adds Vanessa Villalba-Mouco, postdoctoral researcher at the Max Planck Institute and Instituto de Biología Evolutiva.
The archaeological record of the El Argar group shows a clear break with previous Chalcolithic traditions. Burial rites, for example, changed from communal to single and double burials within the building complexes. Elite burials also indicate the formation of strong social hierarchies. Testing for biological relatedness, the researchers found that males are on average more closely related to other people at the site, indicating that the group was likely patrilineally structured. Such a social organization could explain the stark reduction of the Y-lineage diversity.
"We observe similar patterns of social organisation and increasing stratification also in other parts of Early Bronze Age Europe, in fact broadly around the same time and with similar characteristics of early state-like formations. This suggests a structured restart or resetting following some form of crisis or unstable, highly dynamic times," summarises Haak.

Getting a little caught up with GGG.
Phoenician Sailors on shore leave.............................
I was thinking more of tin being a necessary component of bronze (made from smelting tin with copper). So there had to be more intermingling of people in different areas (places where there was tin). If I remember correctly, there were tin mines in ancient Britannia before Christ that were exporting to the rest of Europe.
Yes, and that British tin was carried on Phoenician ships!.............
One has to wonder whether the study was skewed a bit, albeit unintentionally. What bodies were preserved enough for this analysis? Perhaps only the privileged/wealthy...so perhaps these results are not realistic for the population as a whole?
It’s not likely that they are descended from a pre-IndoEuropean coat of paint as it were.

That's one of the, I guess, drawbacks of using surviving evidence. But it's not likely that all these remains were from lavish burials, or that would have been mentioned. Looks like the dating of the various remains cover a wide range, and locations vary.
As I understand it, a similar pattern as in the present Great Britain - Neolithic y chromosomes just find of ended all at once. What were the advantages of Yamnaya (predecessor to corded ware culture) other than just equine animal husbandry? Is this Iberian shift associated with R1a or Robert? Many interesting questions.
R1a or R1b that is.
The suggestion in the paper is, pandemic and climate change (of course). "...the paternally inherited Y chromosome lineages show a complete turnover, linked to the movement of steppe-related ancestry that is also visible in other parts of Europe." Displacement, or maybe an earlier localized LGBTQ campaign of Y extinction led to invasion and domination by men from elsewhere.
With all the bad news these days these threads help keep a sense of sanity and proportion.
That’s why I don’t use bronze.
Being from the steppes, the Yamnaya made great use of wheeled transports. It helped them conquer far and wide.
Bronze — which is very good. Unless something goes wrong. And something *always* goes wrong. Then there’s copper. The only kind I use. It costs money. It costs money, because it saves money.
Thanks for the kind remarks!

I for one would not necessarily associate this particular phenomenon with LGBTQ...
