"The repeated and qualitatively heightened capacity for change" (V. KREMYANSKIY, 1969, p.132).
As he refers himself to ultrastability and variability as they have been studied by ASHBY, KREMYANSKIY writes: "It is known that the latter serves as a means for attaining stability (stabilizing variability); but, in addition (and this is far more important in biological systems), it serves as a means for developing new forms both of the species' stability and also of the variability itself (form-creating variability). It is easily shown that an increased number of components (…) increases variability and has several other advantages" (Ibid).
The concept of ultravariability evoques also the swift and deep upheavels in evolution, to which S.J. GOULD and N. ELDREDGE give the name of punctuated evolution. The "increased number of components" could also be paralleled with the shaping of dissipative structures in systems submitted to giant fluctuations, phenomenon that may lead to the emergence of systems of a new type.
Ultravariability relates obviously to phenomena very different than those considered by the concepts of autopoiesis and organizational closure.
