Idea

Given the concept of the Metabolism First Hypothesis, how did early simple and essentially random reaction networks evolve into ones that exhibit characteristics of scale-free and small-world networks? What physically meaningful rules may we find that can lead to this?

Things to consider

• No predefined goal! Besides evolvability.
• How to define fitness? Or, how to define selection without a known fitness function?
  • Yes, I though it might be interesting to run simulations without fitness and selection, just based on the rules of evolution and see what comes out -- Amelie
    • What to do about the explosion of possibilities? [Tim]
• How can we get increasing complexity of metabolites?

Readings

• nearly anything by Stuart Kauffman (I just borrowed 'The Origins of Order').
