释义 | promorphologyn. Biology. 1. The science of the fundamental morphology of organisms, which aims to describe in mathematical terms the stereometry and symmetries of organic forms; the features of organisms so studied. Now chiefly historical. ΘΚΠ the world > life > biology > study > [noun] > morphology > branches of teratology1842 promorphology1878 metamorphology1879 tectology1883 ecomorphology1960 1878 F. J. Bell & E. R. Lankester tr. C. Gegenbaur Elements Compar. Anat. 2 General Anatomy has to do with the fundamental forms of animal organisms (Promorphology [Ger. Promorphologie]). 1928 Amer. Naturalist 62 216 The possibility of a system of promorphology depends upon the fact that organisms are so constructed that it is possible to compare one part with another. It is merely a logical extension from the facts of bilateral and meristic homology. 1985 Philos. Trans. (Royal Soc.) B. 311 39 The data obtained from the analysis of the promorphology of the Precambrian multicellular animals support theories which derive bilateral animals directly from radial animals. 2002 S. J. Gould Struct. Evolutionary Theory iii. 209 The second science, ‘promorphology,’ tried to establish a physical, or crystallographic basis for organic form. 2. The physical organization of the ovum or very early embryo, considered as prefiguring the subsequent morphology of the embryo or of the mature organism. ΚΠ 1882 Amer. Naturalist 16 392 Dr. Mark presents theoretical considerations and general conclusions regarding the promophology of the ovum, polar phenomena, asters,..and polar globules. 1929 Science 5 Apr. 365/2 There were early studies of polarity, of the predetermination of the embryonic axis, of germinal localization or promorphology in the unfertilized egg. 1943 L. W. Sharp Fund. of Cytol. 129 The egg, before its cleavage or even before its fertilization, may have a definite promorphology, i.e., it has developed an internal organization which in some manner foreshadows the morphology of the young embryo. 1984 Philos. Trans. (Royal Soc.) B. 307 325 Perhaps each early stage provides only enough ‘completeness’ of pattern for the next stage, and not a promorphology of the adult.

Naturalist 51 531 The so-called promorphological characteristics such as shape of egg, type of cleavage, axial relations are as variable as are other characteristics. 1989 Philos. Trans. (Royal Soc.) B. 325 1 The apparently conflicting views of Thompson.., who believed cleavage patterns were determined solely by mechanical forces, and Wilson.., who argued that cleavage patterns had promorphological significance, may thus be reconciled. ˌpromorphoˈlogically adv. rare in terms of or with reference to promorphology.
