  2. Evolutionary taxonomy - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_taxonomy

    Evolutionary taxonomy, evolutionary systematics or Darwinian classification is a branch of biological classification that seeks to classify organisms using a combination of phylogenetic relationship (shared descent), progenitor-descendant relationship (serial descent), and degree of evolutionary change.

  3. Glossary of genetics and evolutionary biology - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_genetics_and...

    An organism or taxon (e.g. a species) which is hypothesized to be the lineal progenitor of two or more organisms or taxa which exist at a later point in evolutionary time. The concept of common descent is fundamental to the study of evolution, phylogenetics, and cladistics; for instance, all clades, by

  4. Descent - Wikipedia

    en.wikipedia.org/wiki/Descent

    Infinite descent, a method going back to Fermat to solve Diophantine equations; Descent (mathematics), an idea extending the notion of "gluing" in topology Hadamard's method of descent, a technique for solving partial differential equations

  5. Outline of evolution - Wikipedia

    en.wikipedia.org/wiki/Outline_of_evolution

    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 ).

  6. Lineage (evolution) - Wikipedia

    en.wikipedia.org/wiki/Lineage_(evolution)

    A lineage is a single line of descent or linear chain within the tree, while a clade is a (usually branched) monophyletic group, containing a single ancestor and all its descendants. [3] Phylogenetic trees are typically created from DNA, RNA or protein sequence data. Apart from this, morphological differences and similarities have been, and ...

  7. Orthogenesis - Wikipedia

    en.wikipedia.org/wiki/Orthogenesis

    Evolutionary progress as a tree of life. Ernst Haeckel, 1866 Lamarck's two-factor theory involves 1) a complexifying force that drives animal body plans towards higher levels (orthogenesis) creating a ladder of phyla, and 2) an adaptive force that causes animals with a given body plan to adapt to circumstances (use and disuse, inheritance of acquired characteristics), creating a diversity of ...

  8. Common descent - Wikipedia

    en.wikipedia.org/wiki/Common_descent

    Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. According to modern evolutionary biology, all living beings could be descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth.

  9. Reticulate evolution - Wikipedia

    en.wikipedia.org/wiki/Reticulate_evolution

    Reticulate evolution refers to evolutionary processes which cannot be successfully represented using a classical phylogenetic tree model, [25] as it gives rise to rapid evolutionary change with horizontal crossings and mergings often preceding a pattern of vertical descent with modification.
