[Morphogenetic loss of shape stability in biological constructions].
The stress-deformation regularities are taken as basic pattern formation factors in biological macrosystems. Mechanical stresses occuring in the growing biological objects give rise to large deformations involving the loss of shape stability with the morphogenetical complication (fold production). Both theory and experiment show that the smaller is construction rigidity of macrosystem (Acetabularia mediterranea and Drosophila melanogaster) the larger is the number of the embryonal folds.
