This makes evolutionary sense, say the researchers, because previous findings suggest that whilst taller men do best with the ladies, it is women of medium height who enjoy the best health, fertility and popularity with men.
But unlike tall men, medium-height women can be more vulnerable to jealousy under some circumstances. Faced with socially or physically powerful rivals they actually felt more jealous than shorter or taller women. According to the study, this may be because tall and strong, or socially well-connected women could well pose a threat to average-height feminine favourites since they might win conflicts, including physical fights. "Taller women are more dominant and have greater fighting abilities than shorter women," write the researchers in Evolution and Human Behavior
