Different approaches to evolutionary interpretation of ontogenies are compared, with special emphasis on the evolutionary role of morphogenetic mechanisms (construction technologies) substantially affecting the structure of definitive forms: they largely determine the structural characteristics of organs, types of anatomical and histological systems, and specificity of symmetry of organisms and their parts. The role of cellular morphogenesis inherited from protozoic ancestors in the morphogenesis of multicellular organisms is demonstrated. Two main ways of improving morphogeneses are considered, based on epithelial morphogenesis and early determined few-celled primordial. On the one hand, the phylogenetic role of archallaxes and deviations is emphasized, these events often switching evolution to a fundamentally new direction. On the other hand, many characteristics of developmental stages are explainable by rationalization of morphogeneses and do not recapitulate ancestral forms, which should be taken into consideration in phylogenetic interpretation of embryogeneses; in particular, this applies to interpretation of axial relationships.
比较了对个体发育进行进化解释的不同方法,特别强调了形态发生机制(构建技术)在进化中的作用,这些机制对最终形态的结构有重大影响:它们在很大程度上决定了器官的结构特征、解剖学和组织学系统的类型,以及生物体及其部分的对称特异性。证明了从原生动物祖先继承的细胞形态发生在多细胞生物形态发生中的作用。基于上皮形态发生和早期确定的少数细胞原基,考虑了改进形态发生的两种主要方式。一方面,强调了原基变化和偏差的系统发育作用,这些事件常常将进化转向一个全新的方向。另一方面,发育阶段的许多特征可以通过形态发生的合理化来解释,并不重演祖先形式,这在胚胎发育的系统发育解释中应予以考虑;特别是,这适用于轴向关系的解释。
