  2. Genetic assimilation - Wikipedia

    en.wikipedia.org/wiki/Genetic_assimilation

    Waddington called the effect he had seen "genetic assimilation". His explanation was that it was caused by a process he called "canalization".He compared embryonic development to a ball rolling down a slope in what he called an epigenetic landscape, where each point on the landscape is a possible state of the organism (involving many variables).

  3. Acclimatization - Wikipedia

    en.wikipedia.org/wiki/Acclimatization

    Acclimatization or acclimatisation (also called acclimation or acclimatation) is the process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH), allowing it to maintain fitness across a range of environmental conditions.

  4. Baldwin effect - Wikipedia

    en.wikipedia.org/wiki/Baldwin_effect

    The Baldwin effect compared to Lamarck's theory of evolution, Darwinian evolution, and Waddington's genetic assimilation. All the theories offer explanations of how organisms respond to a changed environment with adaptive inherited change. In evolutionary biology, the Baldwin effect describes an effect of learned behaviour on evolution.

  5. Adaptation - Wikipedia

    en.wikipedia.org/wiki/Adaptation

    Adaptation is a major topic in the philosophy of biology, as it concerns function and purpose . Some biologists try to avoid terms which imply purpose in adaptation, not least because it suggests a deity's intentions, but others note that adaptation is necessarily purposeful.

  6. Adaptationism - Wikipedia

    en.wikipedia.org/wiki/Adaptationism

    Adaptationism is an approach to studying the evolution of form and function. It attempts to frame the existence and persistence of traits, assuming that each of them arose independently and improved the reproductive success of the organism's ancestors.

  7. Assimilation (biology) - Wikipedia

    en.wikipedia.org/wiki/Assimilation_(biology)

    Assimilation is the process of absorption of vitamins, minerals, and other chemicals from food as part of the nutrition of an organism. In humans, this is always done with a chemical breakdown ( enzymes and acids ) and physical breakdown (oral mastication and stomach churning).

  9. 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 ...
