Fluctuating asymmetry fa
Webcriteria for ideal fluctuating asymmetry, and an open mind about alternative hypotheses. We review these requirements and try to clarify why they are so essential. Studies of fluctuating asymmetry face a number of serious challenges: a) random phenotypic variation arises for reasons other than developmental instability, b) all descriptors of FA http://www.biology.ualberta.ca/palmer.hp/pubs/03BookChapt/PalmerStrobeckChapt.pdf
