Fundamentals about evolution


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
      • 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

Population genetics

  • Population genetics – Subfield of genetics
  • Process
    • Mutation – Alteration in the nucleotide sequence of a genome
    • Selection
       – Mechanism of evolution by differential survival and reproduction of individuals
      • 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
      • Artificial selection
         – Breeding used to develop desired characteristics
      • Ecological selection – Natural selection without sexual selection
    • Gene flow – Transfer of genetic variation from one population to another
    • Genetic drift – Concept in genetics
  • Variation
    • Genetic variation – Difference in DNA among individuals or populations
      • Genetic diversity – Total number of genetic characteristics in a species
      • Gene frequency
         – The relative frequency of a variant of a gene at a particular locus in a population
      • Polymorphism (biology) – Occurrence of two or more clearly different morphs or forms in the population of a species

Evolutionary phenomena

  • Adaptation – Process that fits organisms to their environment
  • Adaptive radiation – A process in which organisms diversify rapidly from an ancestral species
  • Coevolution – Two or more species influencing each other's evolution
  • Concerted evolution
  • Convergent evolution – Independent evolution of similar features
  • Divergent evolution – Accumulation of differences between closely related species populations, leading to speciation
    • Divergent evolution in animals
       – Accumulation of differences between closely related species populations, leading to speciation
  • Evolution of ageing – Study of the evolutionary development of ageing processes
  • Evolution of biological complexity – Tendency for maximum complexity to increase over time, though without any overall direction
  • Evolution of multicellularity
     – The development of organisms that consists of more than one cell from unicellular ancestors
  • Evolution of photosynthesis – Origin and subsequent evolution of the process by which light energy is used to synthesize sugars
  • Evolution of sexual reproduction – How sexually reproducing multicellular organisms could have evolved from a common ancestor species
  • Evolutionary arms race – Competition of sets of genes, traits, or species, that develop adaptations against each other
  • Evolutionary capacitance – Evolutionary biology hypothesis
  • Evolutionary fauna
  • Evolutionary pressure – Any cause that reduces reproductive success in a proportion of a population
  • Evolutionary radiation – Increase in taxonomic diversity or morphological disparity
  • Evolutionary trap – Cases in which an evolved, and presumably adaptive, trait has suddenly become maladaptive
  • Evolvability – Capacity of a system for adaptive evolution
  • Exaptation – Function of trait, shifted by evolution
  • Extinction – Termination of a taxon by the death of its last member
  • Fitness (biology) – Expected reproductive success
    • Inclusive fitness – Measure of evolutionary success based on the number of offspring the individual supports
    • Reproductive success – Passing of genes on to the next generation in a way that they too can pass on those genes
  • Genetic recombination – Production of offspring with combinations of traits that differ from those found in either parent
  • Horizontal gene transfer in evolution – Evolutionary consequences of transfer of genetic material between organisms of different taxa
  • Human evolution (origins of society and culture)
     – Transition of human species to anthropologically modern behavior
  • Inversion (evolutionary biology) – Hypothesis in developmental biology
  • Mosaic evolution – Evolution of characters at various rates both within and between species
  • Parallel evolution – Similar evolution in distinct species
  • Quantum evolution – Evolution where transitional forms are particularly unstable and do not last long
  • Recurrent evolution – The repeated evolution of a particular character
  • Robustness (evolution) – Persistence of a biological trait under uncertain conditions
  • Speciation – Evolutionary process by which populations evolve to become distinct species

Modelling

Taxonomy, systematics, and phylogeny

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 traits
  • Synapomorphy
     – Two concepts on heritable traits
  • 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
