I love this new feature of AncestryDNA!

[Not a Cop]

Not through my matches because I have only 4 matches who are identitied as Dutch and more than 13 as Southern Italian that are much closer than any of my Dutch matches. IBD very likely, as IBD is harder without the right samples (i.e. specific communes in the case of Southern Italy more homogeneity in the case of Dutch people) that's why my Dutch estimate is higher.

Southern Italy is not less homogenous than Dutch, even Brits are overall more homogeonous than Dutch, difference between North and South are huge in Netherlands considering tiny size of the country.

I meant people from the northern and eastern regions of the Netherlands (Noord-Holland and Friesland in particular). How else could you explain the lower estimation for my Southern Italian side, while there are 10 times more Southern Italians tested. Besides that, this is widely known in terms of high haplotype diversity in these regions and low haplotype diversity in the Netherlands.
You'd need more specific samples from communes ore being fully Southern Italian to get high scores with this feature.

Your southern italian is Sicilan IIRC, while ancestry sample seems to be inland, if no than your mother matches Dutch sample more closely, (she's N. Dutch?) while father doesn't match South Italians as good.

Homogenity may be viewed in 2 ways - amounts of different ancestal components (WHG, EEF, ANE, etc.) in that sense S. Italians are closer than N. and S. Dutch.

Second way is overall amount of individuals which participated in ethnogenesis, in that case S. Italians are way ahead of Dutch, most closely related population of Europe, Finns have higher regional diversity in ancestal components than all of Brits f.e., but founding population was very small hence more closely related population.

No my Italian side is all Campanian (mostly Naples north of the city right side of the Vesuvio and southern part of Caserta) and many of my closest matches have Lazio/Campania as 1 community. I've seen other half Brits/ Southern Italians who got a similar score as me and one got Jewish instead of Southern Italian, but is both and this causes the system to flip. Southern Italians didn't migrate so extensively as Dutch people did all over the regions and they sticked in their communities and social class more often. I have an example from my own family tree; I have ancestors from all over Noord-Holland, Friesland and other places around these regions (except the southern parts).

I don't know exactly how they have calculated the results, but surely they used a similar system as 23andme did and not ancient components (measurement of the percentages of the components like the ones you mentioned). As in sharing tiny bits of DNA with the individuals tested that are part of the given population.

AncestryDNA was able to split someone into Sicily and Lazio/Campania though.

Mine changed to Lazio & Campania now

What do the dots on the map mean and the City they give you? Where you plot?

A common spotty Southern Englishman :/ 50% of my DNA

They have also linked your family tree to the map, so that you can quickly see where your ancestors lived and in which period along with the stories they provide. It's not really a PCA but actually a map, which in my case selects the original region of Southern Italians that come from Southern Lazio and Campania that speak Neapolitan (before the risorgimento these area's belonged to the same rulers in most of history after the fall of the Western Roman empire) which they can link to my genome. I haven't seen all the ''communities'' yet, so I don't know how the communities of Abruzzo, Molise, Puglia, Basilicata and Calabria are combined.

It's a nice update and could fairly be called an improvement.

Well in previous post i was just explaining 2 views on a concept of homogenity in genetical sense.

This new feature is obviously based on IBD.

would be cool if they let you upload raw data from other places.

FTDNA didnt let you upload 23andme raw data after a certain test date so i went ahead and paid 60 bucks to upgrade my YDNA results with FTDNA just to get family finder.

A week or two later they updated so you could transfer 23andme data after my test date there...just fuck.
