The 70 pages that link to Genetic drift, each with the reason it gives.

• PhylogeographyRelated: Drift can create geographic genetic differences without requiring a major historical barrier.

• Viral evolutionRelated: Chance bottlenecks can shift viral variant frequencies even when variants have no fitness advantage.

• Mitochondrial EveRelated: Chance extinction of maternal lines helps reduce many ancient lines to one surviving lineage.

• OrthogenesisRelated: It demonstrates that evolutionary change can lack any inherent directional tendency.

• Animal evolutionRelated: It can shape animal populations even when a trait offers no selective advantage.

• Muller’s ratchetRelated: Drift can eliminate the least-loaded class even when its members have higher fitness.

• MutationismRelated: It shows that mutations may spread or disappear without being favored by selection.

• Evolutionary theoryRelated: It changes populations without favoring traits for their effects on fitness.

• Biological anthropologyRelated: It can shape human genetic variation independently of adaptation.

• Divergent evolutionRelated: Chance can amplify differences between separated populations even without contrasting selection.

• Genetic admixtureRelated: Drift after mixing can alter source-related variants independently of further gene flow.

• History of evolutionary thoughtRelated: Its recognition showed that evolution need not always result from adaptive selection.

• MacroevolutionRelated: Drift can drive divergence between populations, especially when they are small or isolated.

• SelectionCompared with: It highlights how chance can alter populations even when selection favors fitness.

• Human evolutionary geneticsRelated: Drift can rapidly alter variation in small human populations, independently of natural selection.

• MicroevolutionRelated: Chance alone can shift frequencies, even when alleles do not affect fitness.

• Motoo KimuraNarrower topic: Drift is the process that can fix neutral mutations without natural selection.

• Alternatives to Darwinian evolutionRelated: It provides a nonselective mechanism that can drive evolutionary change.

• Evolution of bacteriaRelated: Bottlenecks and small populations can shift bacterial genes independently of adaptation.

• Genetic phenomenaRelated: It changes genetic variation even when variants have no fitness advantage.
