In the previous post I said that the trickiest part of all this is the merging of our own data with the Reich's data.
I was wrong, software is easy, the trickiest part is finding the best combinations of populations for qpAdm.
It takes tests and more tests to find them, luckily I had studies to base myself on.
For this analysis I was based mainly on the study The genomic history of the Iberian Peninsula in the last 8000 years by Olalde, 2019.
So far the best values I've found for myself are these:
51% from Portugal EBA (a subset I analyzed separately)
30% from a population with France_Beaker-like ancestry (probably related to the LBA Urnfield culture)
14% from Italy_Imperial (central/eastern Mediterranean ancestry arrived during the Roman Empire)
3% Iberomaurusian
Portugal EBA is made up of 68% of Chalcolithic Portugal and 32% of Germany BellBeaker, which should represent the main ancestry of the Lusitanian peoples. I used the same reference populations.
