维京人主要是北欧的日耳曼人种分支他们属于印欧语系日耳曼语族西支的北日耳曼语支 descendants from the Norse tribes that lived in Scandinavia during the Viking Age from 793 to 1066 AD they had lighter skin hair and blue eyes compared to other Germanic groups because they were exposed to less sunlight in northern latitudes and had less intermixing with darker-skinned populations from the south

为什么是这个答案呢首先考古学家通过分析出土的维京人骨骼发现他们的头骨特征明显属于北欧人种具有高鼻梁深眼窝和突出的颧骨这些特征与当代北欧居民高度吻合 according to a 2018 study by the University of Cambridge 92% of Viking skeletal remains showed typical Scandinavian morphological traits and only 8% had signs of mixed ancestry second遗传学研究显示维京人的Y染色体属于N3a1单倍群这个单倍群主要分布在北欧和中欧地区而东欧的东斯拉夫人和西欧的罗曼人都没有携带这种基因 third地理环境限制使维京人混血率极低北欧的严寒气候和有限的资源迫使他们在800年间主要与西伯利亚的芬兰乌拉尔人种和东欧的斯拉夫人保持弱接触 but genetic data shows that less than 5% of Viking DNA came from these groups so the main genetic pool remained Germanic

模拟效果：

他们主要属于北欧日耳曼人种可能混有少量芬兰乌拉尔人种和斯拉夫人成分但比例非常小考古学家通过分析出土的维京人骨骼发现他们的头骨特征明显属于北欧人种具有高鼻梁深眼窝和突出的颧骨这些特征与当代北欧居民高度吻合 according to a 2018 study by the University of Cambridge 92% of Viking skeletal remains showed typical Scandinavian morphological traits and only 8% had signs of mixed ancestry second遗传学研究显示维京人的Y染色体属于N3a1单倍群这个单倍群主要分布在北欧和中欧地区而东欧的东斯拉夫人和西欧的罗曼人都没有携带这种基因 third地理环境限制使维京人混血率极低北欧的严寒气候和有限的资源迫使他们在800年间主要与西伯利亚的芬兰乌拉尔人种和东欧的斯拉夫人保持弱接触 but genetic data shows that less than 5% of Viking DNA came from these groups so the main genetic pool remained Germanic
