Encyclopaedia Britannica, 11th Edition, Volume 4, Slice 3 "Borgia, Lucrezia" to "Bradford, John" Comments on some recent studies of song bird phylogeny. Thoracic and Coracoid Arteries In Two Families of Birds, Columbidae and Hirundinidae It is not the subject of experiment, and constitutes the phylogeny or the physiology of the formation of determinants. A Mechanico-Physiological Theory of Organic Evolution A memoir on the phylogeny of the jaw muscles in recent and fossil vertebrates. Jaw Musculature of the Mourning and White-winged Doves An outline of the relation of the ontogeny to phylogeny within the Amphibia. Genera of Leptodactylid Frogs in México A similar argument is used in regard to “ontogeny recapitulating phylogeny.” Naturalism And Religion How insignificant are these various periods to the long period originally required; yet in these short periods the whole phylogeny is run through in the ontogeny or the history of the development of the egg. Was Man Created? Thus the progression of the idioplasm controls the phylogeny of the race. A Mechanico-Physiological Theory of Organic Evolution Memoir on the phylogeny of the jaw muscles in recent and fossil vertebrates. The Adductor Muscles of the Jaw In Some Primitive Reptiles The cry of despair addressed to right and liberty by modern society is nothing else than the expression of the instinctive sentiment of anger and revolt produced by the natural evolution of our phylogeny. The Sexual Question A Scientific, psychological, hygienic and sociological study The origin and development of the blastoderm or germinal disc has nothing to do with recapitulation of the phylogeny. Naturalism And Religion This appears rather remarkable, inasmuch as we must assume that in the phylogeny of our species the processes of detumescence appeared earlier. The Sexual Life of the Child Both causes acting together—the phylogenetic configuration of the idioplasm and the successive morphological stages of development of the individual conditioned on it—necessarily result in the ontogeny being the repetition of the phylogeny. A Mechanico-Physiological Theory of Organic Evolution It is clear then that the bacteria are very possibly a heterogeneous group, and in the present state of our knowledge their phylogeny must be considered as very doubtful. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 2 "Baconthorpe" to "Bankruptcy" Conclusions.—What are the principal conclusions to which we are led by this short study of the ancestral history or phylogeny of man? The Sexual Question A Scientific, psychological, hygienic and sociological study But in these writings his main argument is that of his concluding chapter: the spontaneous adaptiveness of the organism, which nullifies all contingent theories to explain the purposiveness in ontogeny and phylogeny. Naturalism And Religion The science of phylogeny, or, as it is popularly called, the evolution of species, had an equally slow growth. The World's Greatest Books — Volume 15 — Science In the further course of phylogeny the division of the cells into two parts takes place regularly. A Mechanico-Physiological Theory of Organic Evolution The ontogeny still passes through the stages of the phylogeny. Darwin, and After Darwin (Vol. 1 and 3, of 3) An Exposition of the Darwinian Theory and a Discussion of Post-Darwinian Questions In its chief outlines ontogeny is determined by phylogeny by means of the laws of heredity, even when it is only an abridged recapitulation. The Sexual Question A Scientific, psychological, hygienic and sociological study What is especially Haeckelian is the “fundamental biogenetic law,” “ontogeny resembles phylogeny,” that is to say, in development, especially in embryonic development, the individual recapitulates the history of the race. Naturalism And Religion Ontogeny: the development of the individual as distinguished from that of the species: see phylogeny. Explanation of Terms Used in Entomology Differentiation is repeated in the course of the phylogeny, since at first all parts of an ontogeny diverge into two or more parts, then the parts of these parts divide again, etc. A Mechanico-Physiological Theory of Organic Evolution Indeed, according to him, phylogeny is not at all capable of direct scientific investigation. At the Deathbed of Darwinism A Series of Papers The fixed appetites and instincts of the species which are proper to every normal man, and are as we have seen fundamentally connected with many animal forms, belong to ancient and profound phylogeny. The Sexual Question A Scientific, psychological, hygienic and sociological study But here the only changes of importance are his four laws, which we translate, and a somewhat different phylogeny of the animal kingdom. Lamarck, the Founder of Evolution His Life and Work We shall accordingly, in this chapter, consider very briefly the history of the earlier views on the phylogeny of the vertebrate stock. Form and Function A Contribution to the History of Animal Morphology The morphological phenomena which find their application in taxonomy, belong exclusively to phylogeny. A Mechanico-Physiological Theory of Organic Evolution The child in whose development the various steps of phylogeny are recapitulated shows this tendency to deception, to simulation, and dissimulation in a very pronounced degree. Studies in Forensic Psychiatry In the previous chapter we have considered the phylogeny of love in general. The Sexual Question A Scientific, psychological, hygienic and sociological study This is the first phylogeny or genealogical tree ever published. Lamarck, the Founder of Evolution His Life and Work Cases of heterotopy, or of organs being developed in a position or a germ-layer other than that in which they originally arose in phylogeny, are not so easy to find. Form and Function A Contribution to the History of Animal Morphology These properties are inherited from the sub-organic kingdom by the plants and animals which follow in the next stage of phylogeny. A Mechanico-Physiological Theory of Organic Evolution This assertion does not deliver us into the hands of teleology, but is based upon the idea that ontogeny and phylogeny are under the same law of growth. The Last Harvest The individual dispositions of recent phylogeny are combined in every way with education, customs, habit and social position to produce results which are often paradoxical, and the factors of which are ambition, vanity, temper, etc. The Sexual Question A Scientific, psychological, hygienic and sociological study Stating its conclusions precisely, science formulates the principle in the following words: individual development is a brief résumé of the history of the species in past times, or, more technically, ontogeny recapitulates phylogeny. The Doctrine of Evolution Its Basis and Its Scope To make full use of the conception of the organism as an historical being it is necessary then to understand the causal nexus between ontogeny and phylogeny. Form and Function A Contribution to the History of Animal Morphology But in the latter case the characteristic of adaptation is again lost in the course of the phylogeny and alternation of generations follows then without regard to the season. A Mechanico-Physiological Theory of Organic Evolution Much of the speculative 'phylogeny,' which abounds among my present contemporaries, reminds me very forcibly of the speculative morphology, unchecked by a knowledge of development, which was rife in my youth. The Advance of Science in the Last Half-Century Between these two extremes there is, however, one important domain, viz., that of recent phylogeny, or in other words variation. The Sexual Question A Scientific, psychological, hygienic and sociological study Of course if you think it more scientific to say that what we are discussing is not Adam and Eve and Eden, but the phylogeny of the blastoderm— SAVVY. Back to Methuselah The Gastræa theory gave point and substance to the biogenetic law, and enabled Haeckel to state much more concretely the parallelism existing between ontogeny and phylogeny. Form and Function A Contribution to the History of Animal Morphology Even Professor Haeckel, of the famous University of Jena, would not deny this, with all that his new terms "ontogeny" and "phylogeny" may imply. Life: Its True Genesis Better some risk of gross thoughts and even acts, to which phylogeny and recapitulation so strongly incline him, than this subtle eviration. Youth: Its Education, Regimen, and Hygiene When the ancestry of a man is well known the roots of his recent phylogeny may be traced to his ancestors. The Sexual Question A Scientific, psychological, hygienic and sociological study The ontogeny of the organs can only be understood in the light of their phylogeny, just as we found of the embryology of the whole body. The Evolution of Man — Volume 2 The assertion is still true that individual organogenesis is exclusively dependent on phylogeny. Form and Function A Contribution to the History of Animal Morphology At the time he began his work biologists were largely busy in a region indicated by Darwin, and roughly mapped out by Haeckel - that of phylogeny. Unconscious Memory More recent investigations have shown that it is of the greatest importance in connection with the comparative anatomy and ontogeny of the vertebrates, and therefore with human phylogeny. The Evolution of Man — Volume 1 Let us begin with a short exposition of the phylogeny of the sentiments of sympathy, or the altruistic and social sentiments. The Sexual Question A Scientific, psychological, hygienic and sociological study It is the most important source of all for special phylogeny; but it has great defects, and often fails us. The Evolution of Man — Volume 2 If this be the case there can be no real recapitulation in ontogeny of the phylogeny of the race, for the egg-cell represents not the first term in phylogeny, but the last. Form and Function A Contribution to the History of Animal Morphology Professor Haeckel in his "Generelle Morphologie" and in another works, has recently brought his great knowledge and abilities to bear on what he calls phylogeny, or the lines of descent of all organic beings. The Origin of Species by means of Natural Selection, 6th Edition Palaeontology is, unfortunately, altogether neglected by many of these new workers, although this interesting science furnishes most important facts for phylogeny, and thus often proves of very great service in ontogeny. The Evolution of Man — Volume 1 We can thus say that the mechanism of appetites belongs to automatic actions deeply inherited by phylogeny. The Sexual Question A Scientific, psychological, hygienic and sociological study The phylogeny of the placenta has become more intelligible from the fact that we have found a number of transitional forms of it. The Evolution of Man — Volume 2 He tried also to explain the recapitulation of phylogeny by ontogeny as due to habit. Form and Function A Contribution to the History of Animal Morphology So well known as to have become a commonplace, is the phylogeny of the horses, which, contrary to all that would have been expected, ran the greater part of its course in North America. Darwin and Modern Science In the whole of the time before this no one had ventured to raise seriously the question of the origin of species, which is the culminating point of phylogeny. The Evolution of Man — Volume 1 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 In tracing the evolution of the various organs we shall follow the method that has hitherto guided us, except that we shall now have to consider the ontogeny and phylogeny of the organs together. The Evolution of Man — Volume 2 If ontogeny is not a recapitulation of phylogeny, how is it that the early embryonic stages are so alike, even in animals of widely different organisation? Form and Function A Contribution to the History of Animal Morphology For many brachiopods, both recent and fossil, the individual development, or ontogeny, has been worked out and has proved to be of great assistance in the problems of classification and phylogeny. Darwin and Modern Science These two branches of our science—on the one side ontogeny or embryology, and on the other phylogeny, or the science of race-evolution—are most vitally connected. The Evolution of Man — Volume 1 Further; among ants which live in societies, the progressive transformation of the species, or phylogeny, has produced a third sex derived from the female sex—the worker; sometimes there is even a fourth—the warrior. The Sexual Question A Scientific, psychological, hygienic and sociological study It is probable that many of the earlier stages of its phylogeny have disappeared without leaving a trace. The Evolution of Man — Volume 2 The brain pattern depends upon his phylogeny, the state of threshold upon his ontogeny. Origin and Nature of Emotions Our attention will be concentrated on the following questions, all relating to the phylogeny of main groups of plants: i. Darwin and Modern Science When we turn our attention to this latest period of embryological research, we pass into the second division of organic evolution—stem-evolution, or phylogeny. The Evolution of Man — Volume 1 The first chapter is a brief statement of phylogeny, followed, as are succeeding chapters, by directions to the student regarding means of study. The Journal of Abnormal Psychology, Volume 10 The recapitulation of phylogeny by ontogeny is only fairly complete in a few cases, and is never wholly complete. The Evolution of Man — Volume 2 The presence of that element produces in the individual an associative recall of the adaptation of his species—that is, the brain pattern developed by his phylogeny becomes energized to make a specific response. Origin and Nature of Emotions The first of these questions has long been the great crux of botanical phylogeny, and until quite recently no light had been thrown upon the difficulty. Darwin and Modern Science Here, and in every other part of embryology, the true key to the solution lies in phylogeny. The Evolution of Man — Volume 1 This "comparative anatomy" and evolution of languages admirably illustrates the phylogeny of species. The Evolution of Man — Volume 2 This remarkable metamorphosis is, however, also interesting because it throws a certain light on the phylogeny of the tail-less apes and man. The Evolution of Man — Volume 2 Fixing the jaw and showing the teeth in anger merely emphasize the remarkable tenacity of phylogeny. Origin and Nature of Emotions We may now, therefore, approach our proper task, and reconstruct the phylogeny of man in its chief lines with the aid of this evidence of comparative anatomy and ontogeny. The Evolution of Man — Volume 2 Roughly, ontogeny may be taken to mean embryology, and phylogeny what we generally call evolution. The Evolution of Man — Volume 1 According to this biogenetic law, ontogeny is a brief and condensed recapitulation of phylogeny. The Evolution of Man — Volume 2 The embryology of the hairs is known in all its details, but there are two different views as to their phylogeny. The Evolution of Man — Volume 2 We must act in this way in constructing the phylogeny of man. The Evolution of Man — Volume 2 The first thought that occurs to one in this connection is the vast difference between the duration of man's ontogeny and phylogeny. The Evolution of Man — Volume 2 The phylogeny of the skull has made great progress during the last three decades through the joint attainments of comparative anatomy, ontogeny, and paleontology. The Evolution of Man — Volume 2 The embryology of all the other parts of the vascular system also gives us abundant and valuable data for the purposes of phylogeny. The Evolution of Man — Volume 2 In every case the duration of ontogeny shrinks into insignificance when we compare it with the enormous period that has been necessary for phylogeny, or the gradual development of the ancestral series. The Evolution of Man — Volume 2 When these Dualistic philosophers are consistent they must assign a moment in the phylogeny of the human soul at which it was first "introduced" into man's vertebrate body. The Evolution of Man — Volume 2 It meets with difficulties equally great and insuperable in embryology and in phylogeny.
