Prolegomenon to a general biology

Area of Science:

• Astrobiology
• Origin of Life Studies
• Theoretical Biology

Background:

• The chapter builds upon foundational concepts from the book "Investigations."
• It addresses the complex interplay between chemical systems and the emergence of life.
• Existing evolutionary theories are examined for their scope and limitations.

Purpose of the Study:

• To introduce the concept of "autonomous agents" in the context of life's origins.
• To explore the role of autocatalytic sets of polymers in abiogenesis.
• To propose a framework for a general biology applicable to any biosphere.

Main Methods:

• Conceptual analysis of autonomous agents and self-replication.
• Discussion of thermodynamic principles related to work cycles in early life.
• Review and critique of current evolutionary biology puzzles.

Main Results:

• Demonstrates how autocatalytic sets can drive the origin of life.
• Highlights the significance of work cycles in biological systems.
• Identifies key challenges in evolutionary theory that a general biology must address.

Conclusions:

• Autonomous agents and autocatalytic sets are crucial for understanding life's origins.
• A universal biology is needed to study biospheres beyond Earth.
• The chapter provides a foundation for a more comprehensive theory of life.
