Data from: Facial width predicts male fitness and rank but not survival in Second World War Finnish soldiers

We investigated fitness, military rank and survival of facial phenotypes
in large scale warfare using 795 Finnish soldiers who fought in the Winter
War (1939-40). We measured bizygomatic facial width vs. height - a trait
known to predict aggressive behaviour in males - and assessed whether
facial morphology could predict survival, lifetime reproductive success
(LRS) and social status. We found no difference in survival along the
phenotypic gradient, however, wider-faced individuals had greater LRS, but
achieved a lower military rank.
