The social "white race" (declared superior to other "races" to rationalize and justify the UK empire parasitation on a half of the world) corresponds with the northwestern european genetic cluster (with the exclusion of the Irish who were conquered by the UK and not considered white despite being the least pigmented population in the world). The intra european clusters are an ultra fine genetic resolution analysis. The genes that in todays population correlate with high IQ spread from ~2000bc likely with the Iran-neolithic genetic component.
