单词 | palingenetic |
例句 | The palingenetic system of the Druids is complete in itself, and takes the being at his origin, and conducts him to the ultimate heaven. Astronomical Myths Based on Flammarions's History of the Heavens 2011-06-24T02:00:15.873Z Does not this seem inevitable, however, considering the palingenetic burden within him? The Book of Khalid In the evolutionary appreciation of the facts of embryology we must take particular care to distinguish sharply and clearly between the primary, palingenetic evolutionary processes and the secondary, cenogenetic processes. Evolution in Modern Thought The loftiest and most suggestive of Egyptian palingenetic symbols is unquestionably that of the egg. Reincarnation A Study in Human Evolution The first I have named palingenetic, the second cenogenetic. Form and Function A Contribution to the History of Animal Morphology The Gastraea bilateralis, of which we may conceive the bilateral gastrula of the amphioxus to be a palingenetic reproduction, represented the two-sided organism of the earliest Metazoa in its simplest form. The Evolution of Man — Volume 2 I regard all those that diverge from the primary palingenetic gastrulation as secondary, modified, and cenogenetic. The Evolution of Man — Volume 1 The palingenetic phenomena, or embryonic recapitulations, are due to heredity, to the transmission of characters from one generation to another. Evolution in Modern Thought The palingenetic phenomena, or embryonic RECAPITULATIONS, are due to heredity, to the transmission of characters from one generation to another. Darwin and Modern Science The gastrula stage was the palingenetic repetition of the ancestral form of all Metazoa, the Gastræa. Form and Function A Contribution to the History of Animal Morphology We must, above all, clearly distinguish between palingenetic and cenogenetic phenomena. The Evolution of Man — Volume 2 As the gastrulation of the amphioxus shows the original palingenetic form in its simplest features, that of the other vertebrates must have been derived from it. The Evolution of Man — Volume 1 In order to distinguish correctly between palingenetic and cenogenetic phenomena in embryology, and deduce sound conclusions in connection with stem-history, we must especially make a comparative study of the former. The Evolution of Man — Volume 2 We saw that the palingenetic form of the heart is a spindle-shaped thickening of the gut-fibre layer in the ventral wall of the head-gut. The Evolution of Man — Volume 2 In this we have throughout taken strict account of the distinction between palingenetic and cenogenetic phenomena. The Evolution of Man — Volume 2 In order to appreciate this important feature, we have distributed the embryological phenomena in two groups, palingenetic and cenogenetic. The Evolution of Man — Volume 2 Its nutritive yelk is much smaller and its formative yelk less obscured with black pigment-cells than in the case of the frog; and its gastrulation has better retained the original palingenetic character. The Evolution of Man — Volume 1 But the special form of segmentation and layer formation which we find in the mammal is by no means the original, simple, palingenetic form. The Evolution of Man — Volume 1 We have, up to the present, only considered that form of segmentation and gastrulation which, for many and weighty reasons, we may regard as the original, primordial, or palingenetic form. The Evolution of Man — Volume 1 Nevertheless, it is not difficult to reduce the whole cenogenetic or disturbed development of this amphigastrula to the true palingenetic formation of the archigastrula of the amphioxus. The Evolution of Man — Volume 1 Moreover, in the animals in which we do not find a real palingenetic blastula the defect is clearly due to cenogenetic causes, such as the formation of food-yelk and other embryonic adaptations. The Evolution of Man — Volume 2 It is precisely in the study of these difficult features that we see the incalculable value of phylogenetic considerations in explaining complex ontogenetic facts, and the need of separating cenogenetic phenomena from palingenetic. The Evolution of Man — Volume 1 We have only recently succeeded, by means of comparative research, in overcoming these difficulties, and reducing this cenogenetic form of gastrulation to the original palingenetic type. The Evolution of Man — Volume 1 Of these four forms we must regard one only as the original palingenetic, and the other three as cenogenetic and derivative. The Evolution of Man — Volume 1 Hence we must once more thoroughly understand the palingenetic embryonic features of the lancelet before we go on to consider the cenogenetic forms of the craniota. The Evolution of Man — Volume 1 In the genealogical tree of the Vertebrates this palingenetic form of segmentation has been preserved in the Amphioxus alone, all the other Vertebrates having cenogenetically modified forms of cleavage. The Evolution of Man — Volume 2 Hence in the light of the gastraea theory we must regard the features of the amphioxus as the only and real primitive structure among all the vertebrates, departing very little from the palingenetic embryonic form. The Evolution of Man — Volume 1 We can, therefore, reduce this cenogenetic form of the discoid segmentation to the palingenetic form of the primitive cleavage. The Evolution of Man — Volume 1 In this we see especially the high scientific value of the biogenetic law and the careful separation of palingenetic from cenogenetic processes.
