Evolution Of Morphological Integration: Developmental Accommodation Of Stress-induced Variation

University of Chicago Press Journals
Summary:
In an article in the September issue of The American Naturalist, Alexander V. Badyaev (University of Arizona) and colleagues show that complexity and cohesiveness of foraging structures of shrews enables accommodation of stress-induced developmental abnormalities in individual components of morphological complexes. Such developmental compensation and accommodation not only allow shrews growing under stressful environments to maintain locally adaptive foraging morphology, but also provide a mechanism for stress-induced evolutionary change.

Stress is a major factor in evolution, but for stress-inducedmodifications to have evolutionary importance they have to be inheritedand persist in a sufficient number of individuals within a population.This requires an organism to survive stress and reproduce at leastonce; thus stress-induced variation has to be accommodated by anorganism without much reduction in its functionality. How is suchaccommodation accomplished?
