Dissecting neural differentiation regulatory networks through epigenetic footprinting : Nature : Nature Publishing Group 2014-12-23T05:00:00Z The disclosure had an interesting echo for me, because one of my first childhood passwords was a play on “ontogeny recapitulates phylogeny,” an evolutionary theory from a high-school biology class that I found especially captivating. The Secret Life of Passwords 2014-11-19T05:00:00Z A computational analysis of limb and body dimensions in Tyrannosaurus rex with implications for locomotion, ontogeny, and growth. Dissecting a crocodile 2012-05-24T17:15:07.103Z However, we note that diversity patterns need not be humped under the island ontogeny model: for example, see Orsonwelles in Fig. The true tempo of evolutionary radiation and decline revealed on the Hawaiian archipelago : Nature : Nature Research 2017-03-14T04:00:00Z It is to be noticed that Weismann’s conception of the processes of ontogeny is strictly evolutionary, and in so far is a reversion to the general opinion of biologists of the 17th and 18th centuries. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 3 "Helmont, Jean" to "Hernosand" 2012-04-14T02:00:23.707Z It is true that there are nonconformities to the general law that individual development tends to recapitulate racial history, or that ontogeny tends to recapitulate phylogeny. Herbert Spencer 2012-02-29T03:00:20.773Z Of all bodily structures, the teeth apparently are under the most rigid genetic controls; they form early in the embryo and follow rigidly specified patterns in their ontogeny. Comparative Ecology of Pinyon Mice and Deer Mice in Mesa Verde National Park, Colorado 2012-02-24T03:00:32.243Z Probably his biggest blunder was his belief in Recapitulation Theory, often expressed as “ontogeny recapitulates phylogeny“. Proteus: How Radiolarians Saved Ernst Haeckel 2012-01-31T21:45:07.440Z Thus, the island ontogeny model, to the extent that it captures the true evolutionary dynamics, provides a complement to the fossil record as a way of identifying negative accumulation rates on evolutionary timescales.

A Guide for the Study of Animals 2011-01-18T03:00:14.913Z Sometimes he calls in ontogeny to countenance the discovery of supposed ancestors: but frequently he does no more than affirm their existence. The Old Riddle and the Newest Answer After this increase in number of parts in a stage of ontogeny, differentiation follows as far as the nature of the functions permits, by the parts most separated passing into each other by intermediate gradations. A Mechanico-Physiological Theory of Organic Evolution Our ontogeny, Dr. Raye, is so simple that it can scarcely be said to exist at all. Freudian Slip That a certain temperature is necessary for ontogeny has long been known; this was carefully studied by O. Hertwig, as was also the influence of heat on the rate of development. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 3 "Electrostatics" to "Engis" 2011-02-06T03:00:53.093Z What is the meaning of the law "The ontogeny is an epitome of the phylogeny"?Who was Weissman? A Guide for the Study of Animals 2011-01-18T03:00:14.913Z Nevertheless, comparative anatomy and ontogeny authorize us in affirming that he once existed. The Old Riddle and the Newest Answer The fact that two organisms belong to the same line of descent is recognized from the ontogeny of the higher including the ontogeny of the lower. A Mechanico-Physiological Theory of Organic Evolution 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 During the period of the development of the individual, that is to say, during its "ontogeny," these characteristics of the germ become expressed in their final or adult form. The Social Direction of Evolution An Outline of the Science of Eugenics Further study of the records, however, soon convinces one familiar with the ontogeny of the case that we are here face to face with the species, described by Alb. The North American Slime-Moulds A Descriptive List of All Species of Myxomycetes Hitherto Reported from the Continent of North America, with Notes on Some Extra-Limital Species Since the stimulus is discontinued with each change of the ontogeny and only the idioplasm persists, permanent variations are produced only in the idioplasm by those conditions that produce visible transformations in the mature organism. A Mechanico-Physiological Theory of Organic Evolution 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? 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 Just as we can obtain by education comparatively useful individuals from comparatively defective germs, so can we more easily damage phylogenetically good germs, by evil influences during their ontogeny. The Sexual Question A Scientific, psychological, hygienic and sociological study Most of our so-called 'psychologists' have little or no knowledge of these indispensable foundations of anthropology—anatomy, histology, ontogeny, and physiology.... Life and Matter A Criticism of Professor Haeckel's 'Riddle of the Universe' Hence a knowledge of the nature of an organism presupposes a complete investigation of its characters in their succession during the whole ontogeny. 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 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 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 Phylogeny: the development of a genus, family, tribe or class: see ontogeny. Explanation of Terms Used in Entomology This differentiation is either one of space between the parts of the ontogeny that appear near each other, or one of time between those that are derived from each other. A Mechanico-Physiological Theory of Organic Evolution In the first place he declares definitely that ontogeny alone, i.e., the development of the individual being, is "capable of a direct scientific investigation." At the Deathbed of Darwinism A Series of Papers But he accepted the main tenet of it when he asserted that each stage of ontogeny had its counterpart in an adult ancestral form. Form and Function A Contribution to the History of Animal Morphology The phenomena of the hereditary mneme show clearly how ontogeny is the result of engraphia combined with selection, in the series of ancestors. The Sexual Question A Scientific, psychological, hygienic and sociological study 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 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 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 The stages which are passed through by higher organisms in their ontogeny correspond to stages which are maintained in others as the definitive organisation. Form and Function A Contribution to the History of Animal Morphology In woman, sexual ontogeny is not the same as in man. The Sexual Question A Scientific, psychological, hygienic and sociological study 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 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 The history of the evolution of a species or group; tribal history; ancestral development as opposed to ontogeny or the development of the individual. Youth: Its Education, Regimen, and Hygiene The Meckel-Serres law, it will be remembered, expressed the idea that the higher animals repeat in their ontogeny the adult organisation of animals lower in the scale. Form and Function A Contribution to the History of Animal Morphology In the sexual ontogeny of normal woman, pregnancies, childbirth, the nursing and education of children play an infinitely greater role than the sexual appetite. The Sexual Question A Scientific, psychological, hygienic and sociological study The truth is that biological processes are not within our powers of conception as those of physics and chemistry are, and Bateson's hypothesis is nothing but the old theory of preformation in ontogeny. Hormones and Heredity 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 In other words, the hypothesis explains heredity as part of the underlying problems of assimilation and of the causes which act directly during ontogeny. Five Lectures on Reincarnation There was the famous case of the regeneration of the lens in Amphibia from the edge of the iris—an entirely novel mode of origin, not occurring in ontogeny. Form and Function A Contribution to the History of Animal Morphology In the laws of ontogeny and heredity alternating ecphoria plays an important part. The Sexual Question A Scientific, psychological, hygienic and sociological study If the evidence of comparative anatomy and ontogeny is ever entirely beyond suspicion, it is certainly the case here. The Evolution of Man — Volume 2 The parts of an ontogeny become dissimilar, since the functions which were previously united become differentiated and since new dissimilar functions are produced in the various parts. A Mechanico-Physiological Theory of Organic Evolution 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 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 they may also be associated in succession, such as those of hearing and of ontogeny. 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 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 Further instances were discovered by two English embryologists, to whom we owe very considerable advance in ontogeny—E. Ray-Lankester and F. Balfour. The Evolution of Man — Volume 1 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 Each individual life thus repeats an entire cycle of development called ontogeny, which is peculiar to all individuals of the species. The Sexual Question A Scientific, psychological, hygienic and sociological study The second chief source of evidence, ontogeny, is not less incomplete. The Evolution of Man — Volume 2 The four factors of Osborn—heredity, ontogeny, environment, selection—play upon and modify endlessly the new form when it is started, but what about the original start? Time and Change It is different in ontogeny; in some of our embryological literature ordinary logic does not count for very much. The Evolution of Man — Volume 1 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 This denture is nothing else than a phylogenetic incident in the ontogeny of the whale. 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 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 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 In this way it comes about naturally that organs which become differentiated rapidly, as, for example, the medullary tube, as a rule dominate earlier periods of ontogeny than do the organs of locomotion. Form and Function A Contribution to the History of Animal Morphology The brain pattern depends upon his phylogeny, the state of threshold upon his ontogeny. Origin and Nature of Emotions In the phylogenetic explanation of them comparative anatomy and ontogeny achieve their greatest triumphs. The Evolution of Man — Volume 2 The second chapter concerns itself with ontogeny, and the student is wisely advised to make drawings of various stages in the development of the brain of one of the higher mammals. The Journal of Abnormal Psychology, Volume 10 Our chief support in this comes from the embryological study of it, or the ontogeny of the soul. The Evolution of Man — Volume 1 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 The intensity of the response depends upon the state of threshold— that is, upon the associative recall of the individual's own experience—his ontogeny. Origin and Nature of Emotions From these pregnant facts of comparative anatomy and ontogeny it follows absolutely that the whole of the Mammals belong to a single natural stem, which branched off at an early date from the reptile-root. The Evolution of Man — Volume 2 This paleontological fact is very important, because it fully harmonises with the evolutionary succession of the Mammal orders that is deduced from their comparative anatomy and ontogeny. The Evolution of Man — Volume 2 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 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 From the comparative anatomy and ontogeny of the existing Marsupials we may draw very interesting conclusions as to their intermediate position between the earlier Monotremes and the later Placentals. The Evolution of Man — Volume 2 It can only be said positively that the peculiar ontogeny of the complicated optic apparatus in man follows just the same laws as in all the other Vertebrates. The Evolution of Man — Volume 2 Whatever further information on the comparative anatomy and ontogeny of the living Catarrhines we may obtain in the future, it cannot possibly disturb this conclusion. The Evolution of Man — Volume 2 Unfortunately, the distinguished Wurtzburg anatomist, to whom comparative anatomy, histology, and ontogeny owe so much, is opposed to the theory of descent generally and to Darwinism in particular. The Evolution of Man — Volume 1 Our comparative investigation of the anatomy and ontogeny of the Amphioxus and Ascidia has given us invaluable assistance. 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 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 We begin with the ontogeny of the Amphioxus. The Evolution of Man — Volume 2 Our historical inquiry into these will be even shorter than that into the work done in the field of ontogeny. The Evolution of Man — Volume 1 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 According to this biogenetic law, ontogeny is a brief and condensed recapitulation of phylogeny. The Evolution of Man — Volume 2 But we have also many important grounds in comparative anatomy and ontogeny for assuming a common origin for all the Vertebrates. 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 This is very clearly shown by the comparative ontogeny of the fishes and amphibia. The Evolution of Man — Volume 1 The origin of the Mullerian duct is still obscure; comparative anatomy and ontogeny seem to indicate that it originates by differentiation from the Wolffian duct. The Evolution of Man — Volume 2 Moreover, many important features in the ontogeny of the vascular system are still very obscure and controverted. The Evolution of Man — Volume 2 Comparative anatomy and ontogeny spoke too clearly for their testimony to be ignored any longer. 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 phylogenetic explanation of polymastism, as given in comparative anatomy, has lately found considerable support in ontogeny. The Evolution of Man — Volume 1 But comparative anatomy and ontogeny teach us that in man and all the other Craniotes the brain is at first composed, not of these two, but of three, and afterwards five, consecutive parts. The Evolution of Man — Volume 2 But the comparative anatomy and ontogeny of the muscular system are much more difficult and inaccessible, and consequently have hitherto been less studied. The Evolution of Man — Volume 2 Comparative anatomy and ontogeny show clearly that the Ganoids descended from the Selachii, and the Teleostei from the Ganoids. The Evolution of Man — Volume 2 We should be quite unable to explain these if comparative anatomy and ontogeny did not come to our assistance. 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 The shortest way to attain our purpose is that followed by Huxley in 1863 in his able work, which I have already often quoted, Man's Place in Nature—the way of comparative anatomy and ontogeny. The Evolution of Man — Volume 2 This instructive and very interesting fact is entirely proved by the concordant evidence of comparative anatomy and ontogeny. The Evolution of Man — Volume 2 The exhaustive study that we made of the comparative anatomy and ontogeny of the Ascidia and the Amphioxus has proved these relations for us. The Evolution of Man — Volume 2 We started from the simplest facts of ontogeny, or the development of the individual—from observations that we can repeat and verify by microscopic and anatomic study at any moment. The Evolution of Man — Volume 2 Finally, we must, in my opinion, count among the chief inductive bases of the theory of evolution the foetal development of the individual organism, the whole science of embryology or ontogeny. The Evolution of Man — Volume 1 Even if we entirely ignore it, all that we have learned from the zoological facts of comparative anatomy and ontogeny as to the placental character of man remains untouched. The Evolution of Man — Volume 2 Here again, therefore, on the ground of the pithecometra-principle, comparative anatomy and ontogeny teach with full confidence the descent of man from the ape. The Evolution of Man — Volume 2 The genealogical tree of the amniote group is clearly indicated in its chief lines by their paleontology, comparative anatomy, and ontogeny. The Evolution of Man — Volume 2 Man has faithfully preserved the main features of his stem-history in the ontogeny of his urinary and sexual organs. The Evolution of Man — Volume 2 |
