Symmetry breaking and functional incompleteness in biological systems.

Area of Science:

• Physics and Biology
• Theoretical and Philosophical Science

Background:

• Symmetry-based explanations, particularly symmetry breaking (SB), are increasingly vital in physics, replacing traditional causal accounts.
• SB is a cornerstone in condensed-matter physics, quantum field theory, nonlinear dynamics, and cosmology.
• Empirical research demonstrates the relevance of symmetries and SB across biological scales.

Purpose of the Study:

• To identify and explain common features of emergence, propagation, and cascading of SB-induced layers in the biosphere.
• To analyze these features from a general philosophical and methodological perspective, considering thermodynamic openness and functional incompleteness.
• To explore the continuity of SB across physical and biological realms and its connection to Darwinism.

Main Methods:

• Analysis of empirical research on symmetries and SB in biological systems.
• Identification of common features in the emergence, propagation, and cascading of SB-induced layers.
• Philosophical and methodological examination of SB in open, functionally incomplete systems.

Main Results:

• Identified common features of SB-induced layers across the biosphere, linked to thermodynamic openness and functional incompleteness.
• Provided a novel philosophical and methodological analysis of these SB features.
• Explored the potential for a unified understanding of SB across physics and biology.

Conclusions:

• Symmetry breaking is a unifying principle applicable to both physical and biological systems.
• The study offers a new perspective on the biosphere's history and evolution through the lens of SB.
• Further research can deepen the understanding of SB's role in biological complexity and Darwinian processes.
