@paxv11: The Brunn type arrived in Northwest England primarily through ancient prehistoric migrations and subsequent centuries of maritime movement across the Irish Sea. Its ultimate genetic roots lie with the robust Upper Palaeolithic and Mesolithic hunter-gatherer populations who inhabited Northwest Europe over 10,000 years ago. During the Bronze Age and subsequent migrations, these distinct genetic lineages became heavily concentrated along the Atlantic fringes, particularly in Ireland and western Scotland. Because Northwest England shares close geographic and economic ties with these regions, centuries of migration, trade, and displacement continually reintroduced and reinforced these physical traits in the local population. Twentieth-century anthropologists noted that the modern presence of this type in England is strongest in western coastal areas, largely driven by the massive influx of Irish and Scottish migrants to major cities such as Liverpool and Manchester during the industrial era. #phenotype
