Maciamo, I read the link you gave me, but some things are not clear for me. The berber genetic intromission in West Iberia is dated between 860 and 1120, and the pattern to the south of the different clades is clearly related with languages and different northern kingdoms of Middle Age Iberia. The present genetic map of Iberian Peninsula is related to the people movements of the last 1000 years. For being sure of what was the genetic map of Iberia before reconquest, it is neccesary to study ancient DNA, actual distribution is not accurate to see that. The study is publicated in 2018 Nature review, signed by Carracedo (USC), Simon Myers, Peter Donnelly and Clare Bycroft (Oxford). About extremely genetic diversity in Galicia and Basque Country between shires, there are recent studies as well.
For me is quite clear, West Iberia (northwest Iberia, Extremadura and central Portugal) completed reconquest against moors very quickly, by then berbers were muslims since little time and religious differences were not as insane as they were lately, so berbers were assimilated, today this component reachs its peak at 10% in some western iberian shires. Central and East Iberia completed reconquest much more lately, by then religious differences were very rough and muslims were sistematically expelled of reconquered territories, even pure iberians who were muslims.
I very hardly believe Basques have high percentages of light color eyes and hair. I can not find the study but I remind a recent and massive study of that, the highest percentage of light color eyes and hair is northern Galicia and west Asturias, and this is reasonably because of combination of climate conditions and higher percentages of germanic genetics.
A person like Laura Prats could be quintessential of west mediterranean appearance, but Iberia is much more than Mediterranean Coast. The appearance of a person like Laura Prats is not common in Atlantic Iberia from Lisbon to San Sebastian, for example, the appareance of Ana de Armas is by far for me more familiar than the one represented by Laura Prats (who in the picture is tanned by summer sun).
Iberia, and Spain, is wide, with very different climate areas, and the diversity of appereances are, by far, more numerous than central and northern european countries. When I lived in Ireland, I saw Irish people is very similar between them, there are scarce diversity in appereances. Galicia is half extension in territory, similar in population and the diversity of appereances in people is very much higher.
