Systemic
Mechanisms (brief overview)
- Variation: Random or directed changes in components (mutations, innovations) that introduce new traits or behaviors.
- Selection: Differential survival or amplification of certain variants based on fitness, utility, or compatibility with the environment.
- Amplification (Positive feedback): Small differences that are reinforced, allowing certain structures or behaviors to grow dominant.
- Stabilization (Negative feedback/homeostasis): Regulatory processes that maintain system integrity and prevent runaway change.
- Self-organization: Local interactions among parts that produce large-scale order without central control (e.g., pattern formation, synchronization).
- Modularity: Organization into semi-independent subunits that can evolve or adapt without disrupting the whole, enabling complexity to increase.
- Co-option/exaptation: Repurposing existing components for new functions, accelerating the emergence of novel structures.
- Scaling laws and constraints: Physical, energetic, and information constraints that shape which structures are viable as systems grow.
- Network effects: Connectivity patterns that change dynamics—hubs, motifs, and community structure influence robustness and adaptability.
- Hierarchical organization: Layers of control and aggregation (components → modules → systems) that permit more complex behavior through layered interactions.
