Here are key facts about the theory of evolution as subject-predicate-object triples:

## Core Concepts
- (Evolution, is, change in heritable traits over successive generations)
- (Natural selection, is, primary mechanism of evolution)
- (Charles Darwin, proposed, theory of evolution by natural selection)
- (Alfred Russel Wallace, co-discovered, natural selection)
- (Evolution, operates on, populations)
- (Evolution, requires, genetic variation)
- (Evolution, produces, biodiversity)

## Mechanisms
- (Natural selection, favors, advantageous traits)
- (Genetic drift, causes, random changes in allele frequencies)
- (Gene flow, transfers, alleles between populations)
- (Mutation, creates, new genetic variation)
- (Sexual selection, drives, evolution of mating traits)
- (Artificial selection, demonstrates, selection principles)

## Evidence
- (Fossil record, documents, evolutionary history)
- (Homologous structures, indicate, common ancestry)
- (Vestigial organs, represent, evolutionary remnants)
- (DNA sequences, reveal, evolutionary relationships)
- (Biogeography, supports, evolutionary patterns)
- (Observed speciation, confirms, evolutionary processes)
- (Comparative embryology, shows, developmental similarities)

## Key Principles
- (Organisms, produce, more offspring than survive)
- (Individuals, exhibit, heritable variation)
- (Environmental pressures, select for, beneficial traits)
- (Favorable traits, increase, reproductive success)
- (Allele frequencies, change, over time)
- (Species, share, common ancestors)
- (Life, descended from, universal common ancestor)

## Evolutionary Processes
- (Speciation, creates, new species)
- (Adaptation, improves, environmental fitness)
- (Coevolution, links, interacting species)
- (Convergent evolution, produces, similar traits independently)
- (Divergent evolution, creates, different traits from common ancestor)
- (Extinction, removes, species from existence)

## Modern Synthesis
- (Modern synthesis, combines, Mendelian genetics with natural selection)
- (Population genetics, explains, evolution mathematically)
- (Genetic mutations, provide, raw material for evolution)
- (Hardy-Weinberg equilibrium, describes, non-evolving populations)
- (Fitness, measures, reproductive success)

## Timeline and History
- (Darwin, published, "On the Origin of Species" in 1859)
- (Mendel's laws, explained, inheritance patterns)
- (DNA discovery, revealed, molecular basis of heredity)
- (Molecular clock, estimates, divergence times)
- (Punctuated equilibrium, describes, rapid evolutionary change)

## Types of Selection
- (Directional selection, shifts, trait distribution)
- (Stabilizing selection, favors, intermediate traits)
- (Disruptive selection, favors, extreme traits)
- (Balancing selection, maintains, genetic diversity)
- (Kin selection, explains, altruistic behavior)

## Molecular Evolution
- (Genes, undergo, duplication and divergence)
- (Neutral mutations, accumulate, without selection)
- (Horizontal gene transfer, moves, genes between species)
- (Endosymbiosis, created, mitochondria and chloroplasts)

## Implications
- (Common descent, unifies, all life)
- (Evolution, explains, antibiotic resistance)
- (Evolutionary theory, guides, conservation efforts)
- (Phylogenetics, reconstructs, evolutionary trees)
- (Evolution, continues, in present time)
