The 143 pages that link to Natural selection, each with the reason it gives.

• Sexual dimorphismRelated: Differences between the sexes can evolve when traits affect survival or reproduction differently.

• Charles DarwinBroader topic: Darwin proposed it as the main mechanism driving evolutionary adaptation.

• BiodiversityRelated: It shapes genetic variation and adaptations that contribute to biological differences.

• Antimicrobial resistanceRelated: Drug exposure favors resistant variants, increasing their share of a microbial population.

• Convergent evolutionRelated: Similar selective pressures can favor similar adaptations in lineages that evolve independently.

• Sexual selectionNarrower topic: Sexual selection is a component of natural selection focused on reproductive differences.

• CamouflageNarrower topic: Predation and other pressures can favor traits that make organisms harder to detect.

• Population geneticsRelated: It shifts allele frequencies when genetic variants affect reproductive success.

• Human evolutionRelated: It favored traits suited to changing climates, diets, pathogens, and ways of life.

• MutationRelated: Selection changes the frequencies of mutations that affect reproductive success.

• Selective breedingCompared with: Unlike selective breeding, it does not require humans to choose parents.

• Genetic driftCompared with: Selection changes frequencies nonrandomly with respect to reproductive success, unlike drift.

• Social DarwinismNarrower topic: Social Darwinism recasts this biological process as a model for human institutions.

• EvolutionRelated: It changes inherited traits when some variants leave more offspring than others.

• Evolutionary biologyRelated: It explains adaptation when inherited differences affect survival or reproduction.

• Endosymbiotic theoryRelated: Selection could favor host–symbiont partnerships that improved survival and reproduction.

• Genetic diversityRelated: Selection can favor some variants while reducing others, changing genetic diversity.

• HomininRelated: Selection can explain how hominin traits changed across generations.

• Evolutionary developmental biologyRelated: Selection acts on traits that developmental processes produce and inherited variation can modify.

• AposematismNarrower topic: Selection can favor signals when they reduce attacks enough to offset their costs.

• MelaninNarrower topic: Selection helps explain the geographic distribution of human pigmentation.

• SpeciesRelated: Different environments can select traits that contribute to lineage divergence.

• Founder effectCompared with: Unlike selection, founder-driven frequency shifts arise from sampling chance rather than fitness differences.

• Parental careNarrower topic: Care can spread when it increases the number of surviving descendants.

• Alfred Russel WallaceNarrower topic: Wallace independently recognized it as a mechanism that can adapt populations to their conditions.

• Evolutionary psychologyNarrower topic: It supplies the central process by which proposed psychological adaptations could have evolved.

• Insecticide resistanceNarrower topic: Insecticide exposure favors insects with traits that let them survive treatment.

• Allele frequencyRelated: Selection changes allele frequencies when alleles affect reproductive success.

• CountershadingNarrower topic: Predation and other visual pressures can favor countershading over generations.

• LamarckismCompared with: It explains adaptation through differential reproduction rather than bodily change caused by use.

• Modern synthesisRelated: The synthesis joined this Darwinian mechanism to genetic inheritance.

• On the Origin of SpeciesBroader topic: Darwin’s central mechanism explains how favorable variations accumulate without foresight.

• Life history theoryNarrower topic: Selection favors allocation patterns that leave more descendants in particular environments.

• Linkage disequilibriumRelated: Selection can create associations among alleles at loci affecting or linked to a selected trait.

• Inclusive fitnessNarrower topic: Inclusive fitness tracks genetic success under natural selection.

• DenisovanRelated: Selection helped preserve some Denisovan-derived variants that benefited modern humans in particular environments.

• AdaptationRelated: Differential reproductive success is the main process that shapes adaptations.

• Common descentRelated: Selection shapes inherited differences after lineages share an ancestor.

• Gene–culture coevolutionNarrower topic: Culturally created selection pressures change which genetic traits spread.

• Ronald FisherRelated: Fisher modeled how selection changes gene frequencies across generations.

• SpeciationRelated: Different environments can favor divergent adaptations in separated populations.

• Batesian mimicryNarrower topic: Predator avoidance can favor individuals whose resemblance to defended species is stronger.

• CoevolutionNarrower topic: Each species changes the traits favored in its interacting partner.

• GradualismRelated: Repeated selection can gradually alter populations across generations.

• Population bottleneckCompared with: Unlike drift in a bottleneck, selection changes allele frequencies nonrandomly with respect to fitness.

• TeleologyRelated: It produces adaptations that appear designed for ends without foresight.

• Behavioral ecologyNarrower topic: It provides the evolutionary mechanism through which behavioral differences can spread.

• Chemical defenseRelated: Predator and pathogen pressures can favor organisms with effective chemical defenses.

• Darwin's finchesRelated: Differences in food supply favor finches whose beaks perform particular tasks well.

• Drug resistanceNarrower topic: Drug exposure favors organisms that already carry traits allowing survival.
