|March 3, 2018
Summary
This study explores how Darwinian evolution principles apply to chemical processes, explaining the emergence of life through molecular information processing. It examines trait valuation, spatial effects, and the shift to symbolic genetic information in early life.
Area of Science:
- Chemical evolution
- Molecular biology
- Origin of life
Background:
- Manfred Eigen extended Darwinian evolution to chemical systems in 1971.
- This framework addresses catalytic networks and molecular information processing.
- It provides a basis for understanding the emergence of life.
Purpose of the Study:
- Investigate general characteristics of chemical evolution scenarios.
- Analyze trait valuation in high-dimensional fitness landscapes.
- Examine spatial compartmentation effects and information transitions.
Main Methods:
- Analysis of continuous dynamical models of evolutionary processes.
- Study of genotype-to-phenotype mapping using Wright and Conrad's ideas.
- Investigation of Schrödinger-like dynamics and high-dimensionality consequences.
Main Results:
- Identified typical dynamical properties of evolutionary models.
- Highlighted the significance of saddle points and Conrad's extra-dimensional bypass.
- Discussed compartment models and self-organized emergence of molecular symbols.
Conclusions:
- Chemical evolution models offer insights into life's origins.
- High dimensionality and spatial factors influence evolutionary trajectories.
- Self-organization drives the transition to symbolic genetic information.
