Fluctuating asymmetry (FA), is a form of biological asymmetry, along with anti-symmetry and direction asymmetry. Fluctuating asymmetry refers to small, random deviations away from perfect bilateral symmetry. This deviation from perfection is thought to reflect the genetic and environmental pressures experienced throughout development, with greater pressures resulting in higher levels of asymmetry. Examples of FA in the human body include unequal sizes (asymme… WebMay 2, 2024 · 4.2 Fluctuating asymmetry and conservation. Several studies have suggested the use of Fluctuating Asymmetry as a potential indicator for environmental stresses (e.g., Leamy et al., 1999; Marchand et al., 2003; Oleksyk et al., 2004), including habitat loss and fragmentation (Anciães & Marini, 2000; Wauters et al., 1996). smart chain bnb to php
