    ‘With few exceptions, animal color patterns show a high degree of bilateral symmetry in shape of pattern elements.’
    • ‘Ours, however, is closed along the plane of bilateral symmetry, resembling the two closed valves of a bivalve rather than being flattened.’
    • ‘Exhibiting external bilateral symmetry about a vertical midline, the human body consists of two enantiomorphs - the right and left sides.’
    • ‘One such indicator is the degree of deviation from bilateral symmetry of faces and bodies.’
    • ‘Therefore, whether subsistence activities involve reliance on one limb more than another or both limbs equally, this should be reflected in measures of bilateral symmetry.’
    • ‘All possible symmetries are explored, but the most common is bilateral symmetry.’
    • ‘Also, protohistoric males exhibit a tendency toward greater bilateral symmetry in humerus dimensions in comparison with preagricultural and earlier agricultural groups, a trend seen in agricultural females as well.’
    • ‘Agricultural females, in particular, showed a clear, although not statistically significant, increase in upper arm robusticity and bilateral symmetry when compared with preagricultural females.’
    • ‘In contrast, when stimuli contain bilateral symmetry, observers' results are consistent with a viewpoint-invariant representation, rather than a viewpoint-dependent representation.’
    • ‘Another trait that may indicate male quality is fluctuating asymmetry, which is measured as small random deviations from bilateral symmetry in morphological traits.’
    • ‘Curiously, bilateral symmetry - and thus the developmental ‘trick’ that makes it possible - seems to have evolved numerous times, independently.’
    • ‘Pronounced changes in bilateral symmetry occurred in males during the protohistoric period, indicating their possible increased involvement in agricultural activities.’

    • ‘Men who exhibit hypothesized fitness indicators, such as high levels of bilateral symmetry, are selected more often by women as affair partners than men with lower levels of symmetry.’
