Dienekes' globe10 calculator : my results

Dienekes released a new calculator (K=10) and here is a brief analyzis of my own results.

For previous K7b results, see : Dienekes' K7b calculator : my results
For a description of 'globe10' : [DODECAD] 'globe10 calculator

My results :

  76.20%  Atlantic_Baltic   
  20.77%  Southern     
  1.05%  West_Asian  
  0.89%  South_Asian     
  0.87%  Amerindian         
  0.21%  Siberian 
  0.01%  East_Asian     
  0.00%  Australasian       
  0.00%  Palaeo_African     
  0.00%  Neo_African        

See the following spreadsheet for results for selected populations :

My individual results are rather similar to previous runs.

 - I am mostly made of a component which peaks in the Atlantic and Baltic (around 85%) and which was the main component of Upper Paleolithic hunter-gatherers, either in modern Gotland (Ajv52 and Ajv70) or in Mesolithic Iberia (Bra1 for La Braña in Asturias).

-  About 20% of my genetic variation is analyzed under the component dubbed "Southern" which peaks in the Middle-East (Arabia, ...) and in North Africa where it can amount for as far as 50% of autochtonous people's genetic variation.

That component was already present in Neolithic farmers such as Oetzi in the Italian Alps or Gok4 in southern Sweden. It undoubtedly originated from the Middle-East and hints to a mixing of aboriginal hunter-gatherer European people with agriculturalist migrants from the Near East.

The Basques (see the aforementioned spreadsheet) do show around 22-24% of "Southern" admixture whereas nearby neighbours who lived in Mesolithic times such as Bra1 do not show such admixture yet. What should it mean ? As far as these results are concerned, it means that the ancestors of Basque people were genetically affected by the wave of agriculturalist migrants who brought agriculture to Europe.

Modern-day Europeans all seem to mostly be a mix of old-stock European genes (dubbed "Atlantic-Baltic") and Middle-Eastern/trans-Mediterranean genes (dubbed "Southern"). The populations least affected by these Neolithic migrants are modern-day North Europeans. Gok4 proves that those "southern"-shifted agricultarists then migrated into Northern Europe where they met the last hunter-gatherers and with whom they eventually mixed (thus diluting the "Southern" component).

- I do show about 1% of West Asian admixture which peaks in the Caucasus and the Middle East as well. The Basques show none. The French do show around 9%, Spaniards around 6% on average (it differs much : around 10% in Balearic Islands as opposed to a rather low 4% in Aragon and Cantabria), Sardinians less than 3%.

That migration, probably associated with the spreading of Indo-European languages, clearly is what differentiates Vasconic people from their European neighbours : Basque ethnogenesis is then a late Neolithic event (which doesn't mean anything about the origins of the Basque language).

Conclusion :

As a whole, I don't differ from Basque people : I am essentially a mix of old-stock European genes and "Southern " ones the origins of which can be debated but seem to date back from the early Neolithic. I also somehow show tiny bits of "West Asian" admixture which might hint to the fact Eastern Béarn was more opened to foreign influence than deep Basque valleys but my admixture remains marginal when compared to the average French results (9 times greater).

  1. Hello,

    I just came across your blog here lately and I find it to be quite interesting. Keep up the good work! :)

    I am curious about trying to sort out and find out what each of the components from the Dodecad globe10 analysis are and mean. I am interested mainly in looking at the Atlantic_Baltic, Southern and West Asian components. Here are my own interpretations of these three components below.

    Atlantic_Baltic: Old stock European genes that are a mixture of Mesolithic and early Neolithic alleles that are present in all Europeans today. The Mesolithic alleles in this component obviously come from ancient European hunter-gatherers from both Northern Europe and the Mediterranean and the Neolithic alleles may have come from the earliest Neolithic farming groups in Europe.

    Southern: Neolithic genes that have a more southern source originating from the Levant and North Africa. Possibly spread into Europe a bit later than the Neolithic part of the Atlantic_Baltic component. Much more purely Neolithic than the Atlantic_Baltic component and have a higher presence in Southern Europe today. More of a trans-Mediterranean Neolithic type component.

    West_Asian: Very late Neolithic or even Copper or Bronze Age arrival in Europe. Originated most likely in the highlands of West Asia and spread out fairly late to Europe and affects Southeastern Europe the most. Originally an early Neolithic component from highland West Asia and more purely Neolithic like the Southern component but from a bit further North in West Asia.

    It would be nice to hear your thoughts on this.


I've chosen to let people comment freely on my posts. Nevertheless, you'll lose your time taunting me and calling me a fascist (which I'm really not) : I pray you to read my introduction which will reassure that my intentions genuinely aim at achieving amateurish knowledge. I understand that you may not share my passion for the history of the peopling of the World, just don't let me know as clear conscience gained by bashing a humble documentary work is useless.
