Genetic Origins of Minoans and Mycenaeans

Guys I missed the tittle Crete_Armenoi in the PCA. Stop being so dramatic, of course I would trust a Harvard scientist over a simple calculator. Goodness!
 
Ok guys
Today something new found,
which gives another dimension among Minoans and Eteocretans

http://www.fimes.gr/2018/08/kriti-minoikoi-tafoi/#axzz5NbvB5Dsl

they have found 2 Minoitic style larnax (bone storage cube) at Ierapetra.
they contain 2 skeletons.

that means 2 mainly things

1 we can have more data about Minoan Geneticks

2 The boundaries among Minoans and EteoCretans are not clear,
since Ierapetra until today was not consider Minoan,
 
This map has been posted here many times, but I found something which I am not aware if it was posted somewhere else but ...
Those triangles in the red circle (very close to Mainland Greeks and Albanians) are labelled wrongly by Laziridis as North Italian, they are in fact Tuscans:

Got this from TheApricity:

No, it's not a mistake. In this set of samples Italy North is everything north of Rome, so it includes Toscana. That's the location of the real break in the genetic cline in Italy.
The triangles to the left or "north" of the Toscani are people like the Bergamo Italians. South of the Tuscans and closer to the Sicilians would be regions like Abruzzo.

Did you really think Lazaridis and most of the great population geneticists of the world would make such a fundamental mistake? Never read theapricity; it rots the brain.

Thank you for the explanation.
 
western anatolian turks definitly overlap with greeks or at least there is no magical gap between them. maybe some of them are pulled away a bit because of their central asian ancestry.

@Angela "Again with the pigmentation. The ancients portrayed women as lighter and men as darker because the men are tanned. Mediterraneans TAN"

maybe it's also because women generally have lighter skin than men probably because they need more sunlight during pregnancy. but when darker skin was considered more manly i imagine lighter skinned women were considered more feminin so the wealthy ones tried to stay out of the sun.
 
See Post 1083. See any overlap there????
 
yes i actually do. the problem is that i don't know from where exactly these point are coming from. here is a graphic from lazardis which shows from where the samples came but not i couldn't find more accurate data.

but it seems like there are only samples from western turkey and eastern turkey but not from between those locations. maybe they took a lot of samples from western turkey and they all plotted near iran or they did not take many samples from western turkey and those they took are actually the ones that plot near the greeks. if that is the case then it could be possible that the area between the turkish dots near greece in that pca and the dots near iran would be completely filled out if there were more samples.

You must have confused the icons. The Turks are round blue circles without a black border. They don't plot near any Greeks at all. The few who are somewhere in no man's land between the island Greeks and Turks (3 out of dozens) may have Balkan ancestry (perhaps Albanian) given the great population exchanges. Even if they are all Turkish for the last 100 years or so, they are outliers.

You need data for conclusions, not one what had speculated before dna or what one wishes were the case. The results are what they are.

If you want to find out where, specifically, they're from, there's usually data on the source of the samples in the paper.

ups sry. i didnt realize that the pca in this forum has different icons. here is the pca from the lazardis study where i took the other picture. here the turks are dark blue triangles.

it's true that my last post is just an assumption but to be fair saying that those points are people with balkan ancestry is also an assumption. what if those points are exactly the ones from western turkey while the rest is from eastern turkey? i will search more data.

Yes, I know. That's why I said they might also be actual Turks who plot nearer, but do NOT overlap with Greeks. Also, they're outliers.

The samples come from the Asymetrix Human Origins Genotype Array. I've never been able to find a site that gives the source for all the samples. I hope you have better luck. It would be very interesting.

Agreed, anyway those in the red circle are indeed Tuscans, that Lazaridis' PCA for everything north of Rome has ony Bergamo HGDP and Tuscan HGDP.

Genetic cline of Italy was already showed by Barbujani 37 years ago. According to Barbujani there is no genetic boundary between the Tuscans and the northern Italians.

On the left, the linguistic boundaries of Italy. On the right, the genetic ones.

It is what it is: whatever yDna the new group that moved into Greece carried, the impact was slight. The analysis in the Supplement is more than excellent, including a new statistical tool that hasn't even been formally released yet, but will soon make its way into Admixtools, I'm sure. The data was analyzed in every possible way. It has to be read carefully. The "steppe" impact was 4-16% or 13-18% depending on the method used. That makes sense because wherever the origin, there would have been dilution all along the way.

The modern Greeks have steppe ancestry of about 20%, and that's in more northern areas. What huge impact did the Slavs have? How does this invalidate the argument for continuity?

Surely we don't have to go over again how yDna is not a reliable predictor of total ancestry? Nor should we have to keep saying again and again that without ancient dna it's all just speculation.

As I elaborated upon above, the impact of the steppe people is going to be very different when encountering a densely populated, culturally advanced area than when reaching large un-or-depopulated areas.

Most modern day Greeks have the majority of their ancestry from people who have been in Greece since the Neolithic. If you extend that to the Bronze Age, it's the vast majority of their ancestry.

Oh, I had forgotten to point to this part of the supporting information.

Symmetry testing of Mycenaeans with Modern Greek populations. He does analyze some samples from Thessaloniki. Take a look.

@Pax, I see we cross-posted. Thanks for posting the actual graphic.

People should really take a look at the map of the areas we're talking about, which I posted upthread. Most of northern Greece was "colonized" by the Greeks, often not until the period of classical Greece. I have in the past posted papers documenting that. It's easily checked.

David Reich, Nick Patterson, and Wolfgang Haak, Krause, etc. are not Greeks of any variety. Claiming ethnic bias is really not going to work in this case.
Do you believe that modern Greeks are largely descended from Mycenaeans?

I will ask you the oposite.
Do you believe that Mycenean or Dorian or NW Greek descendance is upsent from modern Greeks?

I do not believe modern Greeks are largely descended from Mycenaeans, I am not sure about Classical Greeks. We need ancient DNA for that.

Modern Greeks are mostly descended from Neolithic farmers, just like Mycenaeans. Many modern Greeks are brunettes with brown eyes and olive or light olive skin. That’s probably been around in the region for a long time. A good number of Greeks are recognizable, where their looks give away their ethnicity.

Why are Ashkenazi Jews closer to Mycenaeans than Modern Greeks?

Fascinating. I'd love to see your detailed analysis showing where the Reich Lab got it all wrong in this analysis.
