A Synopsis of Neotropical Hylid Frogs, Genus Osteocephalus 2011-10-04T02:00:15.227Z In some species there is considerable ontogenetic change in color pattern, although the juveniles bear the basic color characteristics of the adults. A Revision of Snakes of the Genus Conophis (Family Colubridae, from Middle America) 2011-09-25T02:00:14.967Z Since rate of growth changes rapidly, with a slowing trend, only those young voles that were recaptured within a few weeks showed the approximate growth rate for any specific portion of the ontogenetic curve. Aspects of Reproduction and Development in the Prairie Vole (Microtus ochrogaster) 2011-09-19T02:00:13.453Z It is obvious that we cannot answer the question why the different ontogenetic effects are just what they are.

The Amphibians and Reptiles of Michoacán, México Among these periods the ontogenetic period or ontogeny embraces all generations from one cell to the return of the exactly similar kind of cell. A Mechanico-Physiological Theory of Organic Evolution This occurs ontogenetically, and it occurs phylogenetically through selection. The Adductor Muscles of the Jaw In Some Primitive Reptiles This marvellous complexity of an osmotic growth may be compared with another fact, the ontogenetic development of the ovum, a single cell which under favourable conditions of environment may evolve into a most complicated organism. The Mechanism of Life The ontogenetic development of the sexual appetite and love generally produces in man a peculiar phenomenon. The Sexual Question A Scientific, psychological, hygienic and sociological study Presence of the glands, therefore, cannot be correlated either with sexual or ontogenetic development. The Amphibians and Reptiles of Michoacán, México Later the cell generations of an ontogeny are united by parts into plant individuals; the ontogenetic period consists of a cycle of multicellular and unicellular, or only of multicellular plant generations. A Mechanico-Physiological Theory of Organic Evolution Then only can the course of the psyche be comprehended, ontogenetically as well as phylogenetically, according to a dynamic scheme as it were. Hidden Symbolism of Alchemy and the Occult Arts This ontogenetic fact is supremely important, for the most far-reaching conclusions may be drawn from it. Life and Matter A Criticism of Professor Haeckel's 'Riddle of the Universe' Here again we must distinguish the phylogenetic disposition of woman from the effects of education during her ontogenetic development. The Sexual Question A Scientific, psychological, hygienic and sociological study And what is true ontogenetically, is of course true phylogenetically. The Silesian Horseherd - Questions of the Hour In the lowest forms of cell differentiation the cells of successive generations are all independent; the ontogenetic period consists of a cycle of generations of unicellular plants. A Mechanico-Physiological Theory of Organic Evolution Science may yet have to give up what the Germans call the "ontogenetic directive Force." Natural Law in the Spiritual World There are found in the developmental stages of different Vertebrates 'similar ontogenetic series,' that is to say, Vertebrates show at definite stages similarities with one another in the degree of development of the different organs. Form and Function A Contribution to the History of Animal Morphology Moreover, it presents an individual or ontogenetic evolution during the life of each person, which in its principal traits is predetermined in the germ, by the phylogenetic or hereditary energies of the species. The Sexual Question A Scientific, psychological, hygienic and sociological study A certain succession of stages was observed, the occasional factors are rendered prominent, the constitutional ones are left in the background, and the ontogenetic development receives greater consideration than the phylogenetic. Three Contributions to the Theory of Sex This is perceived from the succession of the visible ontogenetic characteristics which in general run parallel with it. A Mechanico-Physiological Theory of Organic Evolution If this be correct, the phenomenon of second breath, so characteristic of adolescence, and one factor in the inebriate's propensity, is ontogenetic expression of a rhythm trait of a long racial period. Youth: Its Education, Regimen, and Hygiene The ontogenetic and ancestral stages are arranged in parallel columns thus:— Cytula. Form and Function A Contribution to the History of Animal Morphology It is certain that insects descended from worms, and there is no doubt that the larvæ of insects, which are almost worms, represent the ontogenetic repetition of the phylogeny of insects. The Sexual Question A Scientific, psychological, hygienic and sociological study The phylogenetic disposition makes itself visible behind the ontogenetic process. Three Contributions to the Theory of Sex I have not made an ontogenetic study of the senses, and I am therefore unable to describe in detail the course of their development and decline. The Dancing Mouse A Study in Animal Behavior The ontogenetic facts that we gather from this sole survivor of the Acrania are the more valuable for phylogenetic purposes, as paleontology, unfortunately, throws no light whatever on the origin of the Vertebrates. 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 The appearance, which Descartes turned into the premise of the rational discourse adopted by Western civilization, makes us fall captive to representational explanations rather than to ontogenetic descriptions. The Civilization of Illiteracy Among the fossils he indicated "progressive," "synthetic," "prophetic," and "embryonic" types, and pointed out the parallelism which obtains between the geological succession of ancient animals and the ontogenetic development of recent forms. Darwin and Modern Science Prognosis will become definite in proportion to the physician's knowledge not only of the ontogenetic history of the individual patient, but also of the phylogenetic history of the race. Origin and Nature of Emotions We shall have the same experience in the study of the organs in detail, and I shall be compelled to give simultaneously their ontogenetic and phylogenetic origin. The Evolution of Man — Volume 2 This ontogenetic process has a very great significance, and is the real starting-point of the construction of the multicellular animal body. The Evolution of Man — Volume 1 Preceding language, signs functioned based on their ontogenetic condition. The Civilization of Illiteracy The actual ontogenetic development of the gastrula from the blastula furnishes sound evidence as to the phylogenetic origin of the Gastraea from the Blastaea. The Evolution of Man — Volume 2 However, this direct application of ontogenetic facts to phylogenetic ideas is possible, without limitations, only in a very small section of the animal kingdom. The Evolution of Man — Volume 2 For comparative anatomical and ontogenetic reasons, we must not seek these amphibian ancestors of ours—as one would be inclined to do, perhaps—among the tail-less Batrachia, but among the tailed lower Amphibia. The Evolution of Man — Volume 2 These ontogenetic facts are of the greatest importance for the purpose of learning those ancestral forms of the vertebrates which we have to seek in the group of the unarticulated vermalia. The Evolution of Man — Volume 1 As Hasse and Retzius have pointed out, we find the successive ontogenetic stages of its growth represented permanently in the series of the higher Vertebrates. The Evolution of Man — Volume 2 It is both phylogenetically and ontogenetically an independent secondary formation, a later accession to the primary internal ear. The Evolution of Man — Volume 2 The elaborate alimentary canal of the higher animals develops ontogenetically from the same simple primitive gut of the gastrula. The Evolution of Man — Volume 2 The ontogenetic loss of the gills and the tail in the frog and toad can only be explained on the assumption that they are descended from long-tailed Amphibia of the salamander type. The Evolution of Man — Volume 2 The most important feature in this sense, and the best starting-point for ontogenetic study, is the fact that man is developed from an ovum, and that this ovum is a simple cell. The Evolution of Man — Volume 1 In the further ontogenetic development of the alimentary canal in the human embryo the appearance of the gill-clefts is the most important process. The Evolution of Man — Volume 2 The line of argument we followed in this explanation of the ontogenetic facts was simply a consistent application of the biogenetic law. The Evolution of Man — Volume 2 This is the law of the ontogenetic connection of related animal forms. The Evolution of Man — Volume 1 We may, on the ground of the most careful comparative-anatomical and ontogenetic research, formulate the thesis: "Man is in every respect a true Placental." The Evolution of Man — Volume 2 This is an ontogenetic fact of the utmost significance. The Evolution of Man — Volume 1 This phylogenetic principle is as firmly established as the ontogenetic fact that every articulated animal-form develops from an unarticulated embryo. The Evolution of Man — Volume 1 |
