It's becoming well understood that Greece has been under steady but constant genetic overturn from Anatolian migrations from the Neolithic through the Roman era. By the Roman era Tenea was identical to Anatolian proper populations. Most of this was likely mediated from the long since...

I've had this conversation already too many times, but I'll reiterate; the idea of Germanic sources being a source for contribution to the central Italian genepool after the imperial era directly contradicts aDNA we do have from Roman late antiquity for central Italy. The bulk Northerly...

I don't advocate that G25 is the best tool for modelling ancestry, however I would say that it does correlate reasonably well what we see as far as PCA modelling in studies. That doesn't mean that Davidski's 25 dimensional flattening is absolutely sound with reality, but it does show some...

It will be relative to when said admixture took place and how much time under selective pressure, along with the degree or quantity of said selective pressure has been had. A more recent admixture will not have had time to go through many adaptation processes.

A good bit of it is likely natural selection as well. Recall how globular amphora populations had become nearly totally blonde haired, blue eyed and very fair skinned despite having an entirely EEF/Sardinian like genetic structure. The same process likely occurred in reverse for Iranian...

Your results of 73% IA Picene and 26% Imperial are nearly identical to my own. Pretty neat.

Of course: Italy_Imperial: Average...

Individual will nearly always be a tighter fit due to the fact that the model has more data points to reconstruct the target coordinates with. It's simply looking at every individual for each group and trying to replicate the target coordinates by allocating whatever percentage contribution...

The two are just different names for the same dataset derived from Moots' 2019 study. Outliers were excluded for both the average and individual imperial sets. The Pesaro Late Antiquity average is 0.041 from the Italy_Imperial Average. Italy_Imperial is more heavily Aegean drifted by comparison.

To further illustrate my point: Using source population Averages: Using source population individuals: All fits are...

0.0108 is an extraordinarily close fit.

I think it's incorrect to exclude them but more correct to use weighted averages relative to Bergamo's numeric representation in northern Italy. I would also advise that it's very possible you may get results which are far less EEF heavy depending on what village or town the samples come from...

Central Italians can be modeled as a two way admixture between Picene IA/Northern Italic and LBA Aegean/Imperial C. Italian quite accurately which is the historic reality of the situation as per what aDNA studies have revealed to us thusfar. Using Germans, Nords, Levantines and North Africans...

This depends entirely how both theories are qualified and to be honest, like most ethno-political debates, it's unlikely a binary choice, but a gradient plethora of views complete with their own nuance. If nothing else the study strongly indicates that Nordic input was nearly totally absent...

I think if widespread sampling supports the so called "Anti-Normanism theory" then it is only just that we give more credit to it. This seems really a common phenomenon in all states which were ruled at one point by nordic/germanic populations but yet still failed to adopt their language. The...

Great study with lots of sampling. This gives us a great deal of information on the background of the first Slavs - particularly Russians and Ukrainians. I do disagree with some of the abstract as no samples from 700AD onward should be classified as "Ancient" in my opinion since we are well...

You make a very strong thesis. This is perhaps similar to how light hair and light eyes was selected amongst purely EEF populations in the Baltic. EEF of course did not start out majority blonde haired and blue eyed, but enough natural selection due to low sunlight was able to modify the...

I believe in the traditional advice that it's not about aging less and more about aging gracefully. Your appearance seems to fit that idea quite well. I found my first grey hairs when I was 17.
