Chapter 15 Recursive-Hierarchy: A Lesson from the Tardigrade

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

The tardigrade is a small microscopic creature that under environmental stress conditions undergoes cryptobiosis, a temporary metabolic depression, which is a third state between life and death. Cryptobiosis is an unexplained phenomenon. It is argued that this state is biologically obscure from a biological reductionist point of view, however, cryptobiosis makes sense within a different theoretical framework. The ability of the tardigrade to bootstrap itself is interpreted according to Gregory Bateson's idea of a recursive-hierarchy and a topological perspective on thermodynamics. It is argued that the structure of the organism is a recursive-hierarchical structure that allows the organism to conduct processes of reversible computations of which cryptobiosis is just a specific instance. The general meaning of this conclusion is discussed in the context of a scientific non-reductionist approach to biological systems and is used to illustrate the notion of a recursive-hierarchical system.
