This study challenges the claim that evolution can occur without natural selection. The proposed self-other reorganization (SOR) model is shown to be a trivial process, not representing real-world evolution.
Area of Science:
- Evolutionary Biology
- Theoretical Biology
- Origin of Life Studies
Background:
- Gabora and Steel proposed a model for cumulative adaptive evolution without natural selection.
- Their model, self-other reorganization (SOR), involves populations of autocatalytic sets.
- They claimed SOR is relevant to the origin of life and cultural evolution.
Purpose of the Study:
- To analyze the self-other reorganization (SOR) model and its claims of evolution without variation and selection.
- To investigate the validity of SOR as a non-Darwinian evolutionary process.
- To determine the relevance of SOR to biological and cultural evolution.
Main Methods:
- Analysis of the theoretical self-other reorganization (SOR) model.
- Implementation of an extended SOR model with more realistic assumptions.
- Comparison of SOR dynamics with conventional Darwinian dynamics.
Main Results:
- The original SOR model ignores crucial factors like growth, degradation, and non-beneficial effects.
- Under its simplifying assumptions, SOR represents horizontal percolation, not genuine evolution.
- Extended SOR models incorporating realistic dynamics revert to conventional Darwinian processes.
Conclusions:
- The claims supporting SOR as an evolutionary process without variation and selection are challenged.
- SOR's foundation is fragile due to unrealistic assumptions, rendering it irrelevant to real-world evolution.
- The model's focus on only beneficial effects and omission of population dynamics limit its applicability to protocells or cultural evolution.
