# “Endless Forms Most Beautiful and Most Wonderful”: Ruliobiology and the Theoretical Foundations of Biological Form

**[Stephen Wolfram Writings](https://daily.dev/sources/stephenwolfram)** · 37 min read · 0 upvotes · 0 comments

## Summary

Stephen Wolfram introduces ruliobiology, a computational metamodel that tries to explain why biology produces 'endless forms most beautiful and most wonderful'. He evolves 'rulioorganisms' from symmetric 5-color cellular automata seeded by a single cell, mutating rules and keeping changes that preserve or increase a fitness function like lifetime. One evolved organism reached a fitness (lifetime) of 1445 after 2000 steps, nearly 2.5 times the 580 reached at 1000 steps. The patterns show biology-like features: modular organ-like structures, random 'connective tissue', conserved early development, and convergent evolution toward similar shapes via different mutation paths. Wolfram argues computational irreducibility, not natural selection alone, explains the diversity and complexity of biological form.

## Questions this post answers

### What is ruliobiology and how does it relate to Darwin's theory of natural selection?

Ruliobiology is a metamodel of biology that studies systems based on simple rules subject to adaptive evolution, using the methods of ruliology. It argues that Darwin's natural selection alone is insufficient to explain biological form; computational irreducibility, the tendency of simple rules to produce irreducibly complex behavior, is the essential driving force that supplies the raw material on which adaptive evolution acts.

### What cellular automaton setup is used to generate rulioorganisms in Wolfram's ruliobiology experiments?

Symmetric 5-color cellular automata grown from a single-cell seed are used, with rules representing the genotype and the resulting pattern representing the phenotype. Rules are progressively mutated, and mutations are kept only if they increase or maintain a fitness function, most commonly 'lifetime', the number of steps the pattern survives before dying out.

### What is polyplexy in the context of ruliobiology?

Polyplexy is a newly coined term for the phenomenon of having fundamentally different structures appear at every scale of a system, unlike fractal nesting where the same structure repeats at different scales. It was observed ubiquitously in rulioorganisms, where zooming into different levels reveals distinct ordered structures, random connective tissue, and hierarchical organ-like modules.
