Simulation 7: Evolving a Digital Tree — Epoch Walkthrough

This walkthrough pairs world snapshots from GeneGL with most-fit organism views from Gstep at the same epochs. The goal of this simulation was to evolve a tree-like organism within a 2D world. The final organism fits this description beautifully.

How to Read This

  • Left/Top: GeneGL world view at the given epoch (macro ecosystem state).
  • Right/Bottom: Gstep snapshot of the most fit organism at that same epoch (micro phenotype).
  • Notes: Key observations about structure, adaptation, and the evolutionary trajectory.

Epoch 14

World (GeneGL)Most Fit (Gstep)
Epoch 14 WorldEpoch 14 Most Fit

Notes

  • Early evolutionary phase; proto-tree forms begin appearing as branching emerges.
  • The fittest organism favors compact growth to minimize metabolic cost.
  • Strong selection pressure toward energy efficiency over complexity.

Epoch 20

World (GeneGL)Most Fit (Gstep)
Epoch 20 WorldEpoch 20 Most Fit

Notes

  • Organisms begin exhibiting clear vertical and lateral differentiation.
  • Energy-harvesting structures extend outward, resembling primitive canopies.
  • Competition intensifies; structural diversity increases.

Epoch 40

World (GeneGL)Most Fit (Gstep)
Epoch 40 WorldEpoch 40 Most Fit

Notes

  • The environment stabilizes, supporting sustained multi-lineage coexistence.
  • Most-fit organisms show distinctive trunk-and-branch patterns consistent with tree-like evolution.
  • Strong symmetry bias emerges due to fitness weighting.

Epoch 49

World (GeneGL)Most Fit (Gstep)
Epoch 49 WorldEpoch 49 Most Fit

Notes

  • Final evolved organism demonstrates a clear tree-like morphology.
  • Root-like structures (below the main axis) balance energy intake and stability.
  • While it may appear inverted, orientation is irrelevant in a 2D world — the organism has evolved to its optimal form under the given rules.

Reproducing This Walkthrough

  1. Run GeneGL with your configuration until the desired epoch.
  2. Capture a world screenshot (e.g., sim7-epoch-20.png).
  3. Grab the most fit organism from the first line of the Performance log
  4. Open Gstep for the same state and input the most fit organism.
  5. Capture the organism screenshot (e.g., sim7-epoch-20-mostfit.png).
  6. Repeat for each epoch; pair images as shown above.
