Evolution as multilevel learning (Vanchurin et al. 2022)

Vanchurin, Wolf, Katsnelson & Koonin propose that biological evolution—including the origin of life—is multilevel learning: seven principles (P1–P7) that make a universe observable, and ten evolutionary phenomena (E1–E10) that follow from them. Primary source: Toward a theory of evolution as multilevel learning (PNAS 2022, DOI 10.1073/pnas.2120037119). Local copy: PDF.

Principles (P1–P7)

P1. Loss function. In any evolving system, there exists a loss function of time-dependent variables that is minimized during evolution.

P2. Hierarchy of scales. Evolving systems encompass multiple dynamical variables that change on different temporal scales (with different characteristic frequencies).

P3. Frequency gaps. Dynamical variables are split among distinct levels of organization separated by sufficiently wide frequency gaps.

P4. Renormalizability. Across the entire range of organization of evolving systems, a statistical description of faster-changing (higher-frequency) variables is feasible through the slower-changing (lower-frequency) variables.

P5. Extension. Evolving systems have the capacity to recruit additional variables that can be utilized to sustain the system and the ability to exclude variables that could destabilize the system.

P6. Replication. In evolving systems, replication and elimination of the corresponding information-processing units (IPUs) can take place on every level of organization.

P7. Information flow. In evolving systems, slower-changing levels absorb information from faster-changing levels during learning and pass information down to the faster levels for prediction of the state of the environment and the system itself.

Evolutionary phenomena (E1–E10)

Phenomena E1–E7 are generic (learning systems generally); E8–E10 are biological.[^generic]

E1. IPUs. Discrete information-processing units (self-vs. nonself-differentiation and discrimination) exist at all levels of organization.

E2. Frustration. Multidimensional and multiscale optimization problems generically lead to frustration from conflicting objectives at different scales.

E3. Multilevel hierarchy. The hierarchy of multiple levels of organization is an intrinsic feature of evolving biological systems in structure and in the substrate evolutionary forces act upon.

E4. Near optimality. Stochastic optimization tends to rapidly find local optima and keeps the system in their vicinity, sustaining the loss function at a near-optimal level.

E5. Diversity of near-optimal solutions. Solutions on loss-function landscapes span numerous local peaks of comparable heights.

E6. Separation of phenotype from genotype. Dedicated digital information storage media are separated from mostly analog processing devices, with asymmetric information flow from genotype to phenotype.

E7. Replication. Copying and sharing genomic information are essential for long-term persistence of IPUs beyond individual lifetimes.

E8. Natural selection. Darwinian evolution arises when distinct IPUs depend on stored information and can copy and share it, producing differential reproduction of genotypes.

E9. Parasitism. Parasites and host-parasite coevolution are ubiquitous across biological systems and indispensable for the evolution of life.

E10. Programmed death. Programmed (to various degrees) death is an intrinsic feature of life.
