  3. Canalisation (genetics) - Wikipedia

    en.wikipedia.org/wiki/Canalisation_(genetics)

    Through this process of genetic assimilation, an environmentally induced phenotype had become inherited. Waddington explained this as the formation of a new canal in the epigenetic landscape. It is, however, possible to explain genetic assimilation using only quantitative genetics and a threshold model, with no reference to the concept of ...

    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).

  6. Animal embryonic development - Wikipedia

    en.wikipedia.org/wiki/Animal_embryonic_development

    In developmental biology, animal embryonic development, also known as animal embryogenesis, is the developmental stage of an animal embryo. Embryonic development starts with the fertilization of an egg cell (ovum) by a sperm cell (spermatozoon). [1] Once fertilized, the ovum becomes a single diploid cell known as a zygote.

  7. Acclimatization - Wikipedia

    en.wikipedia.org/wiki/Acclimatization

    Acclimatization occurs in a short period of time (hours to weeks), and within the organism's lifetime (compared to adaptation, which is evolution, taking place over many generations). This may be a discrete occurrence (for example, when mountaineers acclimate to high altitude over hours or days) or may instead represent part of a periodic cycle ...

    Assimilation in which new experiences are reinterpreted to fit into, or assimilate with, old ideas and analyzing new facts accordingly. [19] It occurs when humans are faced with new or unfamiliar information and refer to previously learned information in order to make sense of it.
