Fluctuating asymmetry and developmental stability: heritability of observable variation vs. heritability of inferred cause
Fluctuating asymmetry subtle random deviations from perfect bilateral symmetry ~ is an appealing measure of developmental precision because of the apparent ease with which it may be measured and because its developmental origins seem so straightforward (Palmer, 1996). This appeal has led to its wide application as a measure of developmental stability in studies of inbreeding and outbreeding dep...
متن کاملPsychological perspective on human developmental stability and fluctuating asymmetry: sources, applications and implications.
In recent years researchers from diverse disciplines in the life sciences have turned their attention to the issue of developmental stability in the organism. Their key measure, fluctuating asymmetry (FA), is defined as the random, stress-induced deviations from perfect symmetry that develop during the development of bilaterally symmetrical traits. This is regarded as a promising measure of the...

متن کاملFluctuating Asymmetry
Fluctuating asymmetry refers to small random deviations from perfect symmetry in bilaterally paired structures; it is thought to reflect an organism’s ability to cope with genetic and environmental stress during development and its utility as an indicator of such stresses is based on the assumption that perfect symmetry is an a priori expectation for the ideal state of bilateral structures. Flu...
متن کاملFluctuating asymmetry and developmental instability in sagittal craniosynostosis.
OBJECTIVE To determine whether premature sagittal craniosynostosis is associated with developmental instability in the skull by analyzing fluctuating asymmetry in skull shape. DESIGN Cranial shape was quantified by collecting coordinate data from landmarks located on three-dimensional reconstructions of preoperative computed tomography (CT) images of 22 children with sagittal craniosynostosis...
