There are variations between individual and regionals Spaniards, a litlle more than among Portugueses - But the differences are far more evident among Italians and italian regions - Italy can not be considered as a whole -
sure among the autosomals someones are envolved into the individual EXTERNAL VISIBLE phenotypes (and collective ones, even if these last are a matter of discussion) but not all the autosomals - some of them are of different DEEPTH (time) in the species derivations and some external phenotypes (and the autosomals conditioning them) can link people when internal* others separate these people - the autosomals studies have to be pursued further.
* phenotype is the result of genotype + others influences and context, and can be the presence or not of a health defect or an organic fonction, not allways a visible trait, I think -
to me at an external point of view genuine North Italians present very often phénotipycal features that link them more to eastern Frenchmen or to Central Europe people than to Iberian as a whole (more bracycephalic, lighter of pigmentation, heavier bodied etc...) even if it is not to hard to find some individuals very close to Iberians: individuals, NOT the means
