Organization needs organization: Understanding integrated control in living organisms

Area of Science:

• Systems Biology
• Philosophy of Biology
• Theoretical Biology

Background:

• Organization is central to understanding biological systems, with distinct views from new mechanists and autonomy theorists.
• New mechanists emphasize component organization for phenomenon production and productive continuity.
• Autonomy framework focuses on component organization for organism maintenance and self-production.

Purpose of the Study:

• To analyze and compare the new mechanist and autonomy framework accounts of biological organization.
• To argue that integrating both perspectives enhances understanding of biological organisms as cohesively integrated systems.
• To explore control and regulation as bridge concepts between these two frameworks.

Main Methods:

• Characterizing biological mechanisms using constraints, with a focus on control mechanisms.
• Analyzing control mechanisms based on their ability to sense, convey signals, and effect changes.
• Examining examples from unicellular and multicellular systems to illustrate organizational principles.

Main Results:

• Control mechanisms enable organisms to adapt to variations and coordinate parts for viability.
• Biological organisms contain numerous control mechanisms, posing a challenge for understanding their organization.
• Control mechanisms are organized heterarchically, facilitating coordination without centralized control.

Conclusions:

• Integrating insights from new mechanists and autonomy frameworks, via control and regulation, offers a more comprehensive understanding of biological organization.
• Heterarchical organization of control mechanisms allows for effective coordination of internal activities in living organisms.
• This framework supports viewing biological organisms as dynamically integrated systems capable of adaptation and self-maintenance.
