Neutrality is crucial in all forms of evolution. This study examines neutral degree variations in Lindenmayer-systems and their connection to Lempel-Ziv complexity in phenotypes.

Area of Science:

  • Evolutionary biology
  • Theoretical computer science
  • Formal languages

Background:

  • Neutrality plays a key role in natural, molecular, and artificial evolutionary processes.
  • Understanding the genospace and phenotype complexity is essential for evolutionary studies.

Purpose of the Study:

  • To analyze the variation of local neutral degree across the genospace of Lindenmayer-systems.
  • To investigate the relationship between neutral degree variation and Lempel-Ziv complexity of the resulting phenotypes.

Main Methods:

  • Utilizing a simple class of Lindenmayer-systems to model evolutionary processes.
  • Calculating local neutral degree within the genospace.
  • Assessing Lempel-Ziv complexity of the generated phenotypes.

Main Results:

  • Demonstrated variation in local neutral degree across the genospace.
  • Identified a correlation between neutral degree and Lempel-Ziv complexity, suggesting a link between evolutionary neutrality and phenotypic information content.

Conclusions:

  • The study provides insights into the distribution of neutrality in artificial evolutionary systems.
  • Findings suggest that Lempel-Ziv complexity can serve as a measure related to evolutionary dynamics in Lindenmayer-systems.
