Testing for Non-EEF in Italy
I've started using an alternative method for D-stats. Usually D-stats go like this D(OutGroup, PopulationA, PopulationB, Population C) to descipeher if A is closer to B or C. But instead all four positions are taken up by populations. I explain why this differnt form is useful in Strategy #1 here:
Alternative D-stats stratgies.
Results using this strategy are in Sheet "Test #2, Italy" of this spreadsheet:
D-Stats Ideas
Chad Rolfhsen did stats for me with Italians, to test whether they have more German_Beaker and West Asian affinity as
*opposed* to German_Beaker/West Asia than Copper age samples from Northern tip of Italy.
Here's a preview: They confirm modern Italians aren't the same Copper age Northern ones. It also could mean they have German_Beaker and West Asian ancestry. But there's no way to know with these stats, F3-stats could help determine that,

Long Explanation of Stats
As far as I can tell, the stats reveal that......
1: Anatolia_Neolithic Affinity Opposed to German_Beaker: There's a South-North trend in this affinity. Bergamo has the most, Tuscany 2nd, Sicily 3rd, and South Italy 4th. However, Copper Age_Italy's affinity to Anatolia_Neolithic as opposed to German_Beaker is still higher than South Italy's.
2: German_Beaker Affinity Opposed to West Asian: This has the exact same South-North Trend. Bergamo has the most, Tuscany 2nd, Sicily 3rd, and South Italy 4th. Copper Age Italy has more affinity to German_Beaker opposed to West Asians than any modern Italians, except maybe Bergamo.
What 1 and 2 Reveal.
Most importantly Modern Italians and Copper age North Italians are not a clade. Moderns have ancestry Copper age Italians lacked. There's ancestry in Italians that is either German_Beaker and West Asian related or something unrelated to both, which Copper age North Italians lacked.
1: If modern Italians were equally closer to Anatolia_Neolithic opposed to German_Beaker, the result would be 0.000. Instead the results are all negative. These stats don't tell us rather this is because of German_Beaker-like ancestry or not.
2: Similarly, if modern Italians were equally closer to German_Beaker as opposed to West Asians, the results would be 0.000. Instead the results are all positive. meaning Copper age_Italy is closer to German_Beaker opposed to West Asians than modern Italians. These stats don't tell us rather this is because of West Asian-like ancestry or not.
Of West Asians, all Italians are closest to Georgians when opposed to German_Beaker. The others it is closest to are both from the Caucasus: Armenian and Kotais(CHG man). This could mean if there's West Asian admixture in Italy, it's more similar to Caucasus(CHG) than to SouthWest Asians(Druze, Bedouin). But a more likely explanation IMO is the African admixture in SouthWest Asia pull them away.
