Summary

The Meinhardt system in dynamic cell structures shows increased phenotypic complexity compared to static ones. Emergence is defined by a higher ratio of phenotypic to genotypic complexity.

Area of Science:

  • Computational modeling
  • Developmental biology
  • Complex systems

Background:

  • The Meinhardt system is a foundational model for pattern formation.
  • Understanding pattern emergence in biological systems is crucial.

Purpose of the Study:

  • To investigate the Meinhardt system's behavior in static versus dynamic cellular structures.
  • To explore the relationship between genotypic and phenotypic complexity and emergence.

Main Methods:

  • Implementing the Meinhardt system in static 2D grids (8x4 to 128x128 cells).
  • Developing an algorithm to create dynamic 2D cell structures.
  • Implementing the Meinhardt system in dynamic structures with comparable genotypic complexity.

Main Results:

  • Static structures produced periodic patterns.
  • Dynamic structures generated aperiodic patterns with higher phenotypic complexity.
  • Comparable computational cost was observed between static and dynamic structures.

Conclusions:

  • Dynamic cellular structures enhance phenotypic complexity in the Meinhardt model.
  • Emergence is characterized by an increased ratio of phenotypic to genotypic complexity.
  • The study highlights the role of structural dynamics in pattern formation.
