In a period when embryology was assuming increasing importance as an arbiter in settling questions of comparative anatomy, Owen fought a rear-guard action against this trend. Thus Owen, in contrast to Huxley, refused to regard embryology as the criterion of homology. See Russell, op. Cit. (23), Ch. 10. Development of pentameral symmetry in echinoderms occurred coiling and closing up of bilateral asymmetrical trimeral metamery, characteristic of ancestral echinoderms. It originated in the ambulacral system and further developed in other systems under the influence of the original metamery and primary bilateral asymmetry.

Francis (Frank) Maitland Balfour, known as F. M. Balfour, (November 10, 1851 - July 19, 1882) was a British biologist who co-authored embryology textbooks. Mesoderm formation plays a crucial role in the establishment of the chordate body plan. In this regard, lancelet embryos develop structures such as the anteriorly extended notochord and the lateral divertecula in their anterior body. Sep 13, 2019 The aims of Comparative Embryology as restricted in the present work are two-fold: (i) to form a basis for Phylogeny, and (2) to form a basis for Organogeny or the origin and evolution of organs. Comparative embryology is the branch of embryology that compares and contrasts embryos of different species, showing how all animals are related. Assisted Reproductive Technology. Stem cells.

The role of paedomorphosis as a particular case of heterochrony in the origin and evolution of the class Holothuroidea is analyzed. It is shown that holothurians are characterized the presence of some paedomorphic characters (reduced skeleton, absence of an axial complex in the shape of a morphologically integrated structure, single gonad with one gonopore).

[4] The author of the treatise "On the Joints," which Littré calls "the great surgical monument of antiquity," is to be credited with the first systematic attempt at comparative anatomy, for he compared the human skeleton with that of other Vertebrates. Three controversial problems of brachiopod supraordinal classification are discussed: the position of brachiopods in the classification of Metazoa, their classification at phylum and class level, and the classification of the articulate brachiopods. The position of brachiopods in the system of Metazoa remains uncertain.
