As we can see the substructures makes a lot of sense vs the previous analysis but more detailed. As we can see the La Braña is put into a larger branch containing Saamis, Finns, Vologda Russians and Mordovians. Further they are clustered into a subbranch shared only with Vologda Russians and Mordovians. I am not entirely sure why it has this branching as there is not doubt from the heatmap that there is huge sharing with the Finnish-Saami cluster.
What is different between the La Braña individuals vs the Saami-Finns is first of all the obvious larger African like minority admixture. Second we see smaller East-Asian, Siberian minority like admixture. Third we also seem to see smaller West-Asian influence.
In the more subtle it seems the La Braña shows affiliation to the Vologda Russians that the Saami-Finn group dont have possibly explaining some of the clustering. There is also appears to be affiliation to Basque and a Croat.
There also finally appears to be a larger asymmetry in the chromopaints received vs donated suggesting the affiliation between the groups is differentiated in time.
This also rise the question about where this common component seen in La Braña and the Saamis and Finns really come and what time the different infleunces from Africa and Asia arrived.
Wish you included more West Asian populations in this analysis. There are only two West Asian populations in this analysis (if we can call Lezgians West Asian). It is not enough to create a clear West Asian cluster and reveal the real position of West Asians in the worldwide tree. The degree and quality of the genetic relationship between European hunter-gatherers and modern-day West Asians can be used in determining how much Europe has been genetically shaped and transformed after the Neolithic migrations from West Asia.
SvarSlettThe point of this analysis was to shed light on the ancestry of La Braña individuals.
