Green parts of plants, hemoglobin of blood, seasonal coloration of animals, sometimes for self-defense purposes, then for purposes of attacks, mating feathers of birds, in order to attract the attention of a female and grow beyond the limits of individuality - this is a whole series of important examples that are widespread and sufficient meaning of color. It is noticed that with the complication of the organization, with the sophistication of the work of the hair, the ability to form pigment decreases.</p></abstract><trans-abstract xml:lang="ru"><p>Пигментація является однимъ изъ важнѣйшихъ жизненныхъ приспособленій. Зеленыя части растеній, гемоглобинъ крови, сезонная окраска животныхъ то въ цѣляхъ самозащиты, то въ цѣляхъ нападенія, брачное опереніе птицъ, чтобы привлечъ на себя вниманіе самки и расти за предѣлы индивидуальности, — вотъ цѣлый рядъ примѣровъ, широко распространенныхъ и съ достаточной убѣдительностью доказывающихъ важное значеніе окраски. Замѣчено, что съ усложненіемъ организаціи, съ изощреніемъ работы клѣтки способность къ образованію пигмента понижается.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Kazan Medical archive</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Казанский медицинский архив</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list/></back></article>
