This report presents evidence that sexual selection may favor developmental stability (i e, the absence of fluctuating asymmetry) in humans Subtle, heritable asymmetries in seven nonfacial human body traits correlated negatively with number of self-reported, lifetime sex partners and correlated positively with self-reported age at first copulation in a college student sample These relationships remained statistically significant when age, marital status, body height, ethnicity, physical anomalies associated with early prenatal development, and physical attractiveness were statistically controlled The strength of the relationships did not differ significantly as a function of sex It is unlikely that the relationships are generated by false self-reporting of sexual experience

Gangestad & Simpson review sexual selection theory and discuss their work on fluctuating asymmetry and mate preference in humans. We question some aspects of their account and mention problems with the data. We also suggest that more theoretical work on complex but realistic mating systems is required.

AbstractWe address whether fluctuating asymmetry (FA) in an external ear element is correlated with the accuracy of location of a sound source (synthetic male advertisement calls) by female midwife toads (Alytes obstetricans). Fluctuating asymmetry in the tympanum was measured in gravid females. We studied the relationship between FA, snout - vent - length (SVL), and precision in approaching an acoustic stimulus through playback tests. Female mass was negatively correlated with jump length. Tympanum FA was negatively correlated with the accuracy of location of a sound source. Thus, FA can play an important role in sexual selection by conferring an advantage in access to available males by females with low values of asymmetry.

Studies of fluctuating asymmetry (FA) in relation to sexual strategies in humans provide the empirical basis for many arguments in support of good genes sexual selection theory. Many FA studies, however, are flawed by bias in experimental design, inconsistent statistical analysis, and the sloppy handling of data.
