Interactions between diverse proteinoids and microspheres in simulation of primordial evolution

Area of Science:

• Origin of life studies
• Biochemistry
• Evolutionary biology

Background:

• Exploring the chemical origins of life requires understanding how early metabolic pathways could form.
• Proteinoid microspheres are a model system for investigating pre-cellular structures.

Purpose of the Study:

• To demonstrate the conceptual basis for primitive protometabolic pathway lengthening.
• To investigate the potential for adaptive protoselection within microsphere systems.
• To explore the origin of protosexuality in early protocells.

Main Methods:

• Incorporating diverse enzymelike activities into single proteinoid microsphere preparations.
• Observing interactions and enhancements between different enzymelike activities within microspheres.
• Analyzing the effects of combining multiple microspheres on pathway development.

Main Results:

• Demonstrated the ability to integrate multiple enzymelike activities into proteinoid microspheres.
• Observed mutual enhancement of enzymelike activities within the same microsphere.
• Showed that combinations of microspheres can lengthen protometabolic pathways.
• Introduced the concept of internally controlled variation in these systems.

Conclusions:

• Proteinoid microspheres provide a viable model for the origin and lengthening of primitive metabolic pathways.
• Interactions within and between microspheres offer selective advantages, driving adaptive protoselection.
• These findings support the concept of internally controlled variation and offer inferences for the origin of protosexuality.
