To represent the theory of evolution through (subject, predicate, object) triples, we can categorize them into foundational principles, mechanisms, and evidence. 

Here is a structured decomposition of the theory:

### 1. Foundational Principles
* (Life, exhibits, variation).
* (Organisms, possess, heritable traits).
* (Populations, produce, excess offspring).
* (Resources, are, limited).
* (Individuals, compete for, resources).

### 2. Mechanisms of Change
* (Individuals, exhibit, differential survival).
* (Differential survival, constitutes, natural selection).
* (Natural Selection, acts upon, phenotypic variation).
* (Favorable traits, increase, reproductive success).
* (Favorable traits, become, more common).
* (Mutation, introduces, new genetic variation).
* (Genetic drift, causes, random allele fluctuation).
* (Gene flow, alters, population allele frequencies).
* (Natural selection, leads to, adaptation).
* (Adaptation, increases, biological fitness).

### 3. Speciation and Macroevolution
* (Reproductive isolation, facilitates, speciation).
* (Geographic barriers, promote, allopatric speciation).
* (Accumulated changes, lead to, divergence).
* (Common descent, links, all living organisms).
* (Species, share, common ancestors).
* (Macroevolution, occurs over, geological time).

### 4. Evidence for Evolution
* (Fossil record, documents, transitional forms).
* (Homologous structures, indicate, shared ancestry).
* (Vestigial structures, reflect, evolutionary history).
* (DNA sequences, reveal, genetic relatedness).
* (Biogeography, explains, species distribution).
* (Embryonic development, shows, conserved patterns).

### 5. Modern Synthesis
* (Genetics, explains, inheritance mechanisms).
* (Modern Synthesis, integrates, Darwinian selection).
* (Modern Synthesis, integrates, Mendelian genetics).
* (Population genetics, quantifies, evolutionary change).

***

**Summary Logic:**
(Evolution, describes, the process of change).
(Evolution, explains, the diversity of life).
(Natural selection, serves as, the primary mechanism).
