Major Evolutionary Transitions and Multicellularity Challenge
LIFE-SC-19
structural canonical
evolution morphology tree
External: externally open
τ response: structurally constrained
Why do major evolutionary transitions occur: protocells, cells, eukaryotes, multicellularity, tissues, organs, social groups, and complex ecosystems?
Current τ response
See the paired Major Evolutionary Transitions and Multicellularity Challenge — Challenge Response on the Results lane for the program's current response status, registry evidence, verification route, and external-review boundary.
Current status: structurally constrained.
Challenge statement
Why do major evolutionary transitions occur: protocells, cells, eukaryotes, multicellularity, tissues, organs, social groups, and complex ecosystems?
Why this challenge is in the ledger
A structural theory of life should explain why certain increases in organization are stable and repeatable rather than merely historical accidents.
A structural theory of life should explain why certain increases in organization are stable and repeatable rather than merely historical accidents.
τ-facing burden
Recover multicellularity as a colimit or integration of Life Loops; explain how cell, tissue, organ, organism, and ecosystem levels form without losing SelfDesc.
First reviewer questions
- Does τ produce extensional results for major evolutionary transitions and multicellularity challenge?
- Does the framework distinguish promotion from re-description?
- What external review would settle the open questions?
