… Homeostasis was originally a term used to describe the maintenance of an individual's physiological system as described above, but its scope of application has expanded beyond the field of physiology, and it has come to be used to describe a stable dynamic equilibrium state at various levels of biological systems. For example, the stability of the species composition in a biological community is called ecological homeostasis, the stable equilibrium state of gene distribution in a population of the same species is called genetic homeostasis, and the phenomenon of expressing a constant phenotype during the developmental process is called developmental homeostasis.

… ホメオスタシスは元来上記のような個体の生理系の維持を表す語であったが,その適用の範囲は生理学の分野以外にも広げられ,生物系の種々の階層における安定した動的平衡状態を表すのに使われるようになった。たとえば,生物群集における種の構成の安定性を生態的ホメオスタシスとよび,また,同種の個体群における遺伝子分布の安定した平衡状態を遺伝子ホメオスタシス,発生過程で一定した表現型を発現する現象を発生的ホメオスタシスという。【佃 弘子】。… ※「遺伝子ホメオスタシス」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
