bilateral symmetry

noun

  • The property of being divisible into symmetrical halves on either side of a unique plane.

    • ‘Curiously, bilateral symmetry - and thus the developmental ‘trick’ that makes it possible - seems to have evolved numerous times, independently.’
    • ‘Exhibiting external bilateral symmetry about a vertical midline, the human body consists of two enantiomorphs - the right and left sides.’
    • ‘Detecting bilateral symmetry requires the ability to integrate information across an image, because corresponding activity must be found at symmetrical locations across a putative symmetry axis.’
    • ‘It is easy to be biased by bilateral symmetry and assume that a centralized nervous system is necessary for any integrative nervous system function.’
    • ‘All possible symmetries are explored, but the most common is bilateral symmetry.’
    • ‘These were mentioned in the introduction: mesoderm and bilateral symmetry.’
    • ‘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.’
    • ‘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.’
    • ‘The variations in femur morphology and bilateral symmetry observed among the three sample groups are not statistically different.’
    • ‘Emerging evidence suggests that women may also have evolved preferences for mates displaying indicators of good genes such as facial masculinity and 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.’
    • ‘One such indicator is the degree of deviation from bilateral symmetry of faces and bodies.’
    • ‘The subject's bilateral symmetry may be exploited to determine the full 360° of relative aspect for any anatomical region having a left and right component.’
    • ‘Another trait that may indicate male quality is fluctuating asymmetry, which is measured as small random deviations from bilateral symmetry in morphological traits.’
    • ‘With few exceptions, animal color patterns show a high degree of bilateral symmetry in shape of pattern elements.’
    • ‘Pronounced changes in bilateral symmetry occurred in males during the protohistoric period, indicating their possible increased involvement in agricultural activities.’
    • ‘Corallites with bilateral symmetry in the adult stage.’
    • ‘Ours, however, is closed along the plane of bilateral symmetry, resembling the two closed valves of a bivalve rather than being flattened.’
    • ‘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.’
