They were Romans from Imperial Age and Late Antiquity, the authors said it in the supplemental information.
Then, I can't take that Flores-Bello chart seriously.
They are referring specifically to East Mediterranean-related ancestry, from the study :
Interesting bro, why is that?
It is too bad we can’t get samples from north west iberia in this period as it would help explain whether it was found that nafri genetics were found as far as Galicia. If not, then Islamic era migrations of nafri-infused populations most have moved north during that time to explain higher admixtures.The most obvious conclusion is that the Roman period had a significant impact on Iberian genetics, it brought a significant demographic flow from people with ancestry from the Central and Eastern Mediterranean and from North Africa to central and southern Iberia. Ancestry from the Central and Eastern Mediterranean is the WestAnatolia_Roman_Byzantine component in the table that I posted above.
The Germanic peoples were few in number and were absorbed into the mass of the population leaving a small genetic contribution.
The dissemination of North African ancestry in the Roman period is impressive. Nevertheless, this ancestry would not have spread significantly to the north of the peninsula.
This North African ancestry will have increased during the Islamic period and the repopulation of the south/central Iberian Peninsula and the consequent reduction of this NA ancestry, referred by Vitruvius, occurred during the Reconquista and from northern areas where Iron Age ancestry predominated.
We are expected to believe from the Flores-Bello chart above that most modern Spanish are between 40pc to 55pc East Med or Byzantine Roman, or what have you?
Thanks, I was just curious about your opinion.
My knowledge on Iberian historic demography is lacking. Out of curiosity do we have any records indicating a north to south repeopling after the reconquista? SE Iberia is one thing but out of this study it was Meseta which really surprised me, as it does appear to be fairly North African shifted and is rather deep both inland and in the northern half of the peninsula. It doesn't have the dense Iron age dominated clusters that Erbo River shows, either.The most obvious conclusion is that the Roman period had a significant impact on Iberian genetics, it brought a significant demographic flow from people with ancestry from the Central and Eastern Mediterranean and from North Africa to central and southern Iberia.

Western Anatolians during the Roman Era (Anatolian Greeks) are obviously not representative of Italian demography during the Imperial era, even if Italians most certainly were influenced by such genetics from the Magna Graecian era. It would be like trying to equate an Austrian to a Swede, I'd say. I've no doubt that Iberia received some of this type of ancestry but in what context is a very hard question to answer because it appears from my perspective that a lot of those bearing BA aegean/imperial italian like ancestry are already mixed with locals and not so much pure colonizers. We would probably need a timeline that goes further back into the republican era or earlier imperial era to see what the first few generations of the colonizing cluster look like, if it can be found.
I believe the modern Spanish Basques and their neighbours in La Rioja lack North African admixture.
I agree that ~50% Roman era Anatolian is much too high for modern Iberians to be plausable and that's even assuming the ancestry came directly from anatolia which is unlikely. They have aegean like ancestry but it is much less than half.
The majority of romans in the Flores-Bello study clustered with modern South/Central/North Italians, besides other samples that cluster in pops with a little bit higher East Med/Levantine but without being so far away in the PCA with the Italians (In fact they were relatively close each other).
So you're proposing a repopulation by a large movement from basque country and La Rioja? That would certainly be genetically plausible and basques today do indeed plot directly over IA Iberians. I'm curious to see what our Iberian commenters thoughts are on the historicity of this scenario.
Your command of written English is fine.
I'm confused here. Are we talking of West Anatolians? Are we talking of South/Central/North Italians? As Vitruvius points out those are not inter-changeable.
I'm confused too.
I just write what Flores-Bello and his team did, they took and used them to form the Roman label in their study.
