I've scoured papers, forums and blogs, and weirdly to no one does it seem important that losing 40,000 square miles* around the time of a great admixture event seem worth mentioning.
A vast plateau of swamps, sand dunes, peat bogs, deserts and alluvial plains wiped out in a matter of generations. And the people? Can we assume people lived there as most humans of our past lived within a few miles of a major water feature? Then came salinization.
Does anyone think it might be important to how two peoples crash into each other?

* Compilation of geophysical, geochronological, and geochemical evidence indicates a rapid Mediterranean-derived submergence of the Black Sea's shelf and subsequent substantial salinification in the early Holocene
Update 1. See my comment below.
Update 2. "A new approach to the problem of the Neolithisation of the North-Pontic area: is there a north-eastern kind of Mediterranean Impresso pottery?"
Potsherds from a few vessels with Cardium decoration were recently found in old collections of some Neolithic sites of the Northern Black Sea area. A good samples of the valves of brackish water ostracods were discovered in the raw material in most of these vessels. This could indirectly indicate the presence of Neolithic settlements with Cardium pottery on what is now a flooded region of the northern Black Sea coast. Some data show that its inhabitants could have been the initial source of the Neolithisation of neighbouring inland territories. Thus, the whole local Neolithic in the region is interpreted as a northeastern branch of the Mediterranean Neolithic with Impresso and Cardium pottery
Update 3. FrankN wrote this in 2019 "How did CHG get into Steppe_EMBA? Part 2: The Pottery Neolithic" He poopoos on Dmytro Gaskevych's idea that Mediterrean-based Impresso folks settled the area based on adna. Given that Circum-Mediterrean Impresso peoples are probably very heterogenous, I think fairly weak argument. It's a matter of which enclave produced the stream of settlers.
Reading further though, some agreement on the presence of CHG in the North Black Sea. Very reason to think it was more prominent across the ancient northern Black Sea, than just the 1/3 northeasternly portion where we know it was abundant.
"The Black Sea-Lake remained fresh during deglaciation until the marine transgression at 9300 calendar years BP.ReplyDelete
• Prior to the transgression, the Black Sea-Lake level was 120 mbsl or lower.
• The transgression was fast and took no longer than a couple of decades.
•The salinification that followed took <~1500 years." Pretty early for the population genetic history's interesting bits. This is basically pre-Neolithic HGs in most of the areas flooded out and the places flooded out weren't the main source of the Anatolian driven mass migration into Europe in the Neolithic. Still interesting and worth mentioning, but not a driver in Copper or Bronze Age mass migrations or the formative periods of language families that still survive originating from the region.
Here's what we know based on the latest research.ReplyDelete
A rapid flooding of what is now the sea shelf around 7300BC and a salinification period that follows for the next 1500 years.
CHG magically begins appearing in the adjacent, patrilocal hunter population around this time without a suitable proxy. That's at least 5000BC for meaningful, population-wide admixture, but perhaps older than this
There is also speculation that riverine and coastal areas contained a type of Mediterrean-derived Impresso complex (and I'll force the issue and state, Maritime Impresso peoples with origins also in the Northern Levant, either via the Adriatic or Levantine VFR direct. And this would makes sense as it seems they were very capable navigators and seem to have dotted the entire circum-Mediterranean, Atlantic coast and so on. (now I will admit, the Northern Black Sea pottery styles is still an early idea proposed by Dymtro Haskevych, but it is more than reasonable given the latest researches on the Impresso Horizon.)
In any case, a situation may exist in which an ecological disaster precipitated changes in the location and economies of the peoples who lived in these areas. Heavier reliance on terrestial food sources (cattle and sheep)
If it is the case that the Black Sea was souring for the Impresso Peoples who lived and depended on the mollusks and fishes of the sea and deltas, they may have progressively inched northwards into fresher waters along the rivers putting them more directly in contact with hunters.
Actually, I believe the closest proxy is indeed Levantine, not Iranian. Clue.Delete
Hi bellbeakerBlogger... Good to have you back.ReplyDelete
It took only two (Aratashen and Marsis blur) marginal Shulaveri-Shomu individuals to stop the Reich Lab on their tracks and now they agree (with me) that PIE was Shulaveri!
They do not have enough Shulaveri DNA to make a paper with a title close to : “ …Shulaveri-Shomutepe is the origin of PIE and the CHG for the ethnogenesis of steppe autosomal DNA” – But it’s read in-between the lines of this latest Lazaridis paper! – Its all there but the header.
Again, I was the only one on record ever to fight for this. - The Shulaverian Hypothesis is mine and mine alone. It needs to be said. Honor to whom honor is due I suppose.
As Lazaridis says, they need more samples for Shulaveri-Shomu and is incredible how they still mention Armenia and Azerbaijan when in fact the Bulk of Shulaveri were actually in Georgia. And it’s important. Georgia Shulaveri-Shomu for over 1200 years admixed with the descendents of Kotias Klide and also with many of the Chokh people in mountainous Daghestan and that is relevant to the samples we have for individuals in the steppe Caucasus eneolithic. Same is true to the ones that are showing up at about the same time with Anatolian with are the ones derived from Shulaveri and ended up in Yamnaya genetic formula.
Anyways… its just all a matter of time, is it not?

Parfait, j'apprécie. merci Bernard!ReplyDelete
Interesting but not convincing :)ReplyDelete
and the reason for that is there is no Cardial or Neolithic of any sort in north AnatoliaReplyDelete
. Gaskegych is grasping at straws here .
For the CHG question, the sea of relevance would be the Caspian one over the black one in my opinion. The caspian during the mesolithic is highly interesting, after the LGM it swells up immensely effectively creating a sea separating eastern europe from central asia/siberia. What follows is the receding of the mega caspian sea, of which you can still see the imprint in the topography today.ReplyDelete
