palingenetic

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.

2 In this we see especially the high scientific value of the biogenetic law and the careful separation of palingenetic from cenogenetic processes.

3 In this we have throughout taken strict account of the distinction between palingenetic and cenogenetic phenomena.

4 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.

5 The palingenetic phenomena, or embryonic RECAPITULATIONS, are due to heredity, to the transmission of characters from one generation to another.

6 The first I have named palingenetic, the second cenogenetic.

7 The palingenetic phenomena, or embryonic recapitulations, are due to heredity, to the transmission of characters from one generation to another.

8 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.

9 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.

10 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.

11 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.

12 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.

13 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.

14 The palingenetic system of the Druids is complete in itself, and takes the being at his origin, and conducts him to the ultimate heaven.

15 The loftiest and most suggestive of Egyptian palingenetic symbols is unquestionably that of the egg.

16 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.

17 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.

18 Of these four forms we must regard one only as the original palingenetic, and the other three as cenogenetic and derivative.

19 In order to appreciate this important feature, we have distributed the embryological phenomena in two groups, palingenetic and cenogenetic.

20 Does not this seem inevitable, however, considering the palingenetic burden within him?
