a, Mean dance ability of males (filled bars throughout) and females (open bars throughout) by level of bodily symmetry. Error bars represent 95% confidence intervals. P values for within-sex are shown. b, Mean strength of symmetry preference (that is, evaluations of asymmetrical dancers subtracted from evaluations of symmetrical dancers) by sex of dancer and sex of evaluator. Error bars represent 95% confidence intervals. P value at top of panel indicates significantly greater female than male evaluator preference for symmetrical male dancers.
