Hypothesis

Can two competing template cycles coexist within the same chemoton model?

Conclusion

The study demonstrates that two competing templates can coexist in a chemoton due to the coupling of chemical reactions.

Supporting Evidence

  • The chemoton model can maintain stable cell cycles under various conditions.
  • The introduction of a two-state switch allows for controlled cell growth and division.
  • The coexistence of templates suggests that Eigen's paradox may be more relaxed than previously thought.

Takeaway

This study shows that in a simple model of life, two different types of templates can live together and help each other grow.

Methodology

The chemoton was implemented using the BlenX programming language and simulated with a stochastic model to observe the behavior of competing templates.

Limitations

The model does not account for random variations in template generation, which could affect evolutionary dynamics.
