    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Developmental psychobiology posed this question since the lack of knowledge about the precise coordination of all cells, even those not related anatomically, in space and time during the embryonic period does not allow us to understand what forces at the cellular level coordinate four very general classes of tissue deformation, namely: tissue ...

  3. Evolutionary biology - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_biology

    Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution holds that all species are related and gradually change over generations. [1]

  4. Phylogenetic comparative methods - Wikipedia

    en.wikipedia.org/wiki/Phylogenetic_comparative...

    Phylogenetic comparative methods (PCMs) use information on the historical relationships of lineages (phylogenies) to test evolutionary hypotheses.The comparative method has a long history in evolutionary biology; indeed, Charles Darwin used differences and similarities between species as a major source of evidence in The Origin of Species.

  5. McDonald–Kreitman test - Wikipedia

    en.wikipedia.org/wiki/McDonald–Kreitman_test

    The McDonald–Kreitman test [1] is a statistical test often used by evolutionary and population biologists to detect and measure the amount of adaptive evolution within a species by determining whether adaptive evolution has occurred, and the proportion of substitutions that resulted from positive selection (also known as directional selection).

  6. Evolutionary game theory - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_game_theory

    1) The model (as evolution itself) deals with a population (Pn). The population will exhibit variation among competing individuals. In the model this competition is represented by the game. 2) The game tests the strategies of the individuals under the rules of the game.

  7. Outline of evolution - Wikipedia

    en.wikipedia.org/wiki/Outline_of_evolution

    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

  8. Evolutionary physiology - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_physiology

    Evolutionary physiology is the study of the biological evolution of physiological structures and processes; that is, the manner in which the functional characteristics of organisms have responded to natural selection or sexual selection or changed by random genetic drift across multiple generations during the history of a population or species. [2]

  9. Ecology and evolutionary biology - Wikipedia

    en.wikipedia.org/wiki/Ecology_and_evolutionary...

    Ecology and Evolutionary biology in North America is based on research impact determined by the top 10% of ecology programs. The interactive web of organisms and environment are all part of what the field of Ecology explores. There have been studies in evolution that have worked to prove that "modern organisms have developed from ancestral ones."
