Supportmix for three German chromosomes

I still don't know, what to think about it, but was curious enough to reanimate my elder chromosome stylesheets and populate them in three examples with the latest results of Polakos chromosome paintings. There is no German reference group, so German admixture has to be composed with neighbour populations. I had a look on chromosomes 7, 9 and 12.








I see some ancestry countries, which seem plausible ( East English, Lithuanian, Ukrainian, Vologda, Chechen, Bulgarian_Romanian or even Swedish ) but some are rather unlikely, like Tuscan, Spanish, Irish, Iranian or Saudi Arabian.

A bellybutton in Helsinki

a nice opportunity to mention:

Björn Otto, a German pole vaulter, today grasped for the EM title in Helsinski and at the end won silver. He belonged to those people, whose bellybutton I faced in a series of more than 500 drawings, called "MyBelly is the middle of the web" (2000 - 2002 at http://zaender.tripod.com/index.htm). My vision was the simulation of a social network, reaching far back in time and connecting people via their real relationships, represented through their navel. This series was preceding and both awakening my genetic interest, functioning exactly like a mitochondrial phylotree. Drawings were kept anonymous, only the dates of birth and drawings are listed plus the title "My bellybutton" in native tongue. Here I show two, who went public with the works themselves.

A blow on German Eurogenes participants

Eurogenes ran an extended version of the last SPA analysis, including individuals from Pakistan and North India, just to test their effect on the other samples, as David W. stated.
I thought, if there is an impact, we should somehow SEE it.
So I made 4 simple maps, in each centering another German participant, one from the middle (DE28), one from the Southwest (DE31), the Southeast (DE12) and one from the outer Northwest (PLDE2). To avoid misunderstandings, these are NOT screenshots of SPA_dual plots. I just overlapped two different versions of SPA_single runs, one with and one without Indian samples and marked the differences for German participants

pie charts don't seem to go with my ancestry avatars, but perhaps columns in some way:

Genetic avatars

Figurines like the "Venus of Willendorf" ( 22 kybp ) always had a fascination for me, standing in a totally different aesthetic and cultural context. Whether they are a product of male fantasy or a ritual addition in a maternal surrounding, guarding the tent or an idol for fertility will perhaps never be complete cleared. But in a period of determining genetic components for an admixture analysis, I thought, it would be great to associate such female mother/goddess figurines with a certain population component. It would just be helpful, if at the end of an experimental process we could fix a component to a limited region and a certain timeframe, which could be represented by an icon in a senseful colour.
The oldest known figurines, including the new recent finding of the german "Venus of Hohler Fels" (35 - 40 kybp) are tied together in a belt, reaching from Southwest France to Sibiria.





After this homogenous paleo- and mesolithic area, which could have lasted for more than 30000 years, more abstract and diverging types are popping up.





Genetic data are globally not distributed equal like Descarte's "common sense" (Nobody ever has claimed to have herited less of it than others) nor are these figurines. They are clearly clustering in a neolithic period in the Neareast, the Danube bassin and the amerindian high cultures of Inca and Maya.









Even examples of the japanese Jomon culture are numerous, while early pieces for China and a lot of other parts of the world are still lacking. But perhaps we get enough of them covering what we need.
