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
One notices, in several of these recent works on embryology, that their authors are too little acquainted with comparative anatomy and classification. The Evolution of Man — Volume 1
I there made a thorough investigation of the almost unknown embryology of the siphonophorae. The Evolution of Man — Volume 1
This is particularly clear as regards the comparative embryology of the vertebrates, because here the phylogenetic unity of the stem has been already established by the well-known facts of paleontology and comparative anatomy. The Evolution of Man — Volume 1
We already know from embryology the manner in which the gut develops in the embryo of man and the other mammals. The Evolution of Man — Volume 2
The causal character of the relation which connects embryology with stem-history is due to the action of heredity and adaptation. The Evolution of Man — Volume 1
Here, and in every other part of embryology, the true key to the solution lies in phylogeny. The Evolution of Man — Volume 1
Roughly, ontogeny may be taken to mean embryology, and phylogeny what we generally call evolution. The Evolution of Man — Volume 1
This important discovery was bound to be of service to embryology, as it raised a number of new questions. The Evolution of Man — Volume 1
The complete unity of structure which is thus revealed by the comparative anatomy of the limbs is fully confirmed by their embryology. The Evolution of Man — Volume 2
Among the many great services which Baer rendered to embryology, especially vertebrate embryology, we must not forget his discovery of the human ovum. The Evolution of Man — Volume 1
Hundreds of assiduous and able observers are now engaged in the development of comparative embryology and its establishment on a basis of evolution, whereas they numbered only a few dozen not many decades ago. The Evolution of Man — Volume 1
This must be said of the many contributions of mechanical embryology which take up a position of hostility to the theory of descent and its chief embryological foundation—the biogenetic law. The Evolution of Man — Volume 1
This law, however, when rightly understood, is not opposed to, but is the best and most solid support of, a sound mechanical embryology. The Evolution of Man — Volume 1
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
Scarcely any piece of knowledge has contributed so much to the advance of embryology as this; its formulation is one of the most signal services to general biology. The Evolution of Man — Volume 1
The embryology of man and the animals, the history of which we have reviewed in the last two chapters, was mainly a descriptive science forty years ago. The Evolution of Man — Volume 1
This gifted scientist succeeded in mastering, by a complete reform of the science, the great difficulties which the cellular theory had at first put in the way of embryology. The Evolution of Man — Volume 1
But this attempt was bound to miscarry, since its not very clear-headed author lacked a sound acquaintance with embryology and the cell theory, and even with the structure and development of the tissue in particular. The Evolution of Man — Volume 1
It meets with difficulties equally great and insuperable in embryology and in phylogeny. The Evolution of Man — Volume 2
A new branch of embryological research has been studied very assiduously in the last decade of the nineteenth century—namely, "experimental embryology." The Evolution of Man — Volume 1
All the best recent research in animal embryology has led to the confirmation and development of Baer and Remak's theory of the germinal layers. The Evolution of Man — Volume 1
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
They are furnished in the strongest form by the data of comparative anatomy and embryology, completed by paleontology. The Evolution of Man — Volume 1
Far more intricate are the processes of human embryology; in these are condensed and comprised thousands of the phylogenetic processes. The Evolution of Man — Volume 2
Wilhelm Roux, in particular, has made extensive experiments, and based on them a special "mechanical embryology," which has given rise to a good deal of discussion and controversy. The Evolution of Man — Volume 1
I say this is very important, because our whole science of embryology now resolves itself into the problem: "How does the multicellular organism arise from the unicellular?" The Evolution of Man — Volume 1
