Ávila : Castile and León (Spain)

In pre-Roman times (5th century BC), it was inhabited by the Vettones, who called it Obila ("High Mountain") and had here one of their strongest fortresses. The Vettones were apparently a group of tribes of Hispano-Celtic and Celtiberian origin organized since the 3rd Century BC into a tribal confederacy of undeterminated strength. Even though their tribes’ names are obscure, the study of local epigraphic evidence has shed some light here, allowing the positive identification of the Calontienses, Coerenses, Caluri and Bletonesii, but the others remain unknown.

A predominantely cattle-herder people that practiced transhumance, archeology has identified them with the local 2nd Iron Age ‘Cogotas II’ Culture, also known as the ‘Culture of the Verrascos’ (verracos de piedra), named after the crude granite sculptures representing pigs, wild boars and bulls that still dot their former region.

  • Sample :

Full scale

  • Brief anthropological analysis :

- Type 1 :
Dark complexion (dark hair but rather pale skin), brachymorphic, broad face, round features, short and broad nose, wide-set eyes, wide-spaced sloping and rather chinky eyes
~ Alpinoid

This type was abundantly found in Portuguese and Leonese areas : it would fit a "Berid" definition. It seems to be quite widespread in the whole NW corner of the Iberian peninsula.

- Type 2 : Intermediate complexion, leptomorphic, narrow "horsy" face, long and straight nose, high cheekbones, a rather broad jaw, close-set eyes, rather narrow eyelids
~ Atlanto-Mediterranean

This is a basic Iberian type. Somehow, these people remind us of neighbouring "horsy" Portuguese types. Another series can be identified which is characterized by angular facial features alongside puffy and rather unimpressive secondary features (nose, ...).

[Dodecad Ancestry Project] Update : K=64 for Dodecad Project members

As a prelude, for those reading my weblogs, don't worry, I just don't have much time to upload them. Still I've got tons of samples waiting for being updated.

Just a piece of news then : Dienekes updated his Dodecad project with a K=64 analysis. This time I was included : I'm DOD133.

Clusters Galore results, K=64 for Dodecad Project members (up to DOD307)

Unfortunately enough, Dienekes' privacy policy doesn't allow an easy identification of project members . Browse this topic for more info on participants. The results show that :

- Iberians cluster together at K=22 along with 3 North Italians and 5 Frenchmen. The 15 Dodecad project members can more or less all be identified.
- The French Basques define their own cluster at K=38.
- Rather interestingly, I define my own cluster at K=22 : to be more precise I'm joined by another Frenchman from the Lyons sample who must be that dot with Basque tendencies used by most companies and amateur geneticists (Dienekes, Polako, 23andme, ...). One can fairly deduce that this man from Lyons is either Gascon or a recent mix of Basque ancestry and a more mainstream French one (which might give similar results). Which is another proof that this Lyons sample should not be used without further data about who sampled individuals are.
