In biology, evolution is change in the heritable characteristics of biological organisms over generations due to natural selection, mutation, gene flow, and genetic drift. Also known as descent with modification. Over time these evolutionary processes lead to formation of new species (speciation), changes within lineages (anagenesis), and loss of species (extinction). "Evolution" is also another name for evolutionary biology, the subfield of biology concerned with studying evolutionary processes that produced the diversity of life on Earth.

Introduction

Basic principles

  • Macroevolution – Evolution on a scale at or above the level of species
    • Speciation – Evolutionary process by which populations evolve to become distinct species
      • Natural speciation
        • Allopatric speciation – Speciation that occurs between geographically isolated populations
        • Peripatric speciation – speciation in which a new species is formed from an isolated smaller peripheral populationPages displaying wikidata descriptions as a fallback
        • Parapatric speciation – Speciation within a population where subpopulations are reproductively isolated
        • Sympatric speciation – Evolution of a new species from an ancestor in the same location
      • Artificial speciation
      • Hybrid speciation – Form of speciation involving hybridization between two different species
    • Despeciation – Loss of a species of animal due to its combining with another species
    • Anagenesis – Gradual evolutionary change in a species without splitting
    • Extinction – Termination of a taxon by the death of its last member
  • Microevolution – Change in allele frequencies that occurs over time within a population
    • Artificial selection – Breeding used to develop desired characteristics
    • Natural selection – Mechanism of evolution by differential survival and reproduction of individuals
      • Sexual selection – Mode of natural selection involving the choosing of and competition for mates
    • Mutation – Alteration in the nucleotide sequence of a genome
    • Gene flow – Transfer of genetic variation from one population to another
    • Genetic drift – Concept in genetics

Fundamentals

Basic concepts of phylogenetics

  • Phylogenetic tree – Branching diagram of evolutionary relationships between organisms
  • Phylogenetic network – Graph used to visualize evolutionary relationships, including reticulation events
  • Long branch attraction – Systematic error in phylogenetics
  • Clade – Group of a common ancestor and all descendants
  • Grade – Non-monophyletic grouping of organisms united by morphological or physiological characteristics
  • Ghost lineage – Phylogenetic lineage that is inferred to exist but has no fossil record

Inference methods

Current topics

Group Traits

  • Symplesiomorphy – An ancestral character or trait state shared by two or more taxa
  • Apomorphy – Two concepts on heritable traitsPages displaying short descriptions of redirect targets
  • Synapomorphy – Two concepts on heritable traitsPages displaying short descriptions of redirect targets
  • Autapomorphy – Distinctive feature, known as a derived trait, that is unique to a given taxon

Group Types

  • Monophyly – Property of a group of including all taxa descendant from a common ancestral species
  • Paraphyly – Type of taxonomic group
  • Polyphyly – Property of a group not united by common ancestry
