Too many pundits and gurus of "Culture" and too many prophets of Separation and Apartheid - And very few people finding similarities or building bridges between "Cultures".
Scientific Facts :
1) English, Spanish and French are not so distant languages. England was conquered by the Normans that spoke Middle Age French in 1066, the high classes of England spoke French for two centuries. The interaction between England, Spain and France has been very constant for thousands of years, thanks to the short distances, Wars, Fashions, Books, Commerce, Travelers, etc...
2) It has been established that England and the larger United Kingdom was genetically conquered by some Iberians or Primitive Basques after the Ice Age 12,000 or less years ago. According to the Leading Geneticists of England that was the most important influence in English DNA and the subsequent genetic influences of "Celts", Romans and Anglo-Saxons are much less important than previously thought. Some English linguists believe that the Anglo-Saxons were a wider germanic population from Belgium, Netherlands, etc... Many doubts about the big or small number of Anglo-Saxons.
The "Anglo-Saxon" genes are more Germanic than "Anglo-Saxon" and only have some small influence in East Anglia or Eastern England. They are never the dominant pool of genes, even in the "Anglo-Saxon" area.
So, you can not judge Human Genetic Relationships by the Exterior Aspect or apparent Phenotypes of Humans, because changes can be extremely exterior and shallow and evolve very fast under climate, environment, social forces, social selection, etc .... ( this is Darwinian Evolution )..
This is like races of dogs that appear very different but are extremely closely related ( genetically ) .... All of them coming from wild wolves, not long ago.
I could develop similar theories about Law, Constitutions, Government, Art, Religion, Philosophy, etc.... but this would become tiring and boring. And at the end, extremely idiotic.
