Web1. What is a Child? Almost single-handedly, Philippe Ariès, in his influential book, Centuries of Childhood (Ariès, 1962), has made the reading public aware that conceptions of childhood have varied across the centuries. The very notion of a child, we now realize, is both historically and culturally conditioned. Haeckel formulated his theory as "Ontogeny recapitulates phylogeny". The notion later became simply known as the recapitulation theory. Ontogeny is the growth (size change) and development (structure change) of an individual organism; phylogeny is the evolutionary history of a species.

WebThe phrase “ontogeny recapitulates phylogeny” was coined by Ernst Haeckel in 1866 and for many decades was accepted as natural law. Haeckel meant it in the strict sense: that an organism, in the course of its development, goes through all the stages of those forms of life from which it has evolved. Modern biology now rejects this dogmatic ... WebI. INTRODUCTION. Ontogeny is the development of an individual; phylogeny is the develop-ment or evolution of species. The phrase “Ontogeny recapitulates phylogeny” is attributed to Ernst Haeckel in the mid nineteenth century (first published 1866), although the idea appears as early as the 1790s. WebAbstract.
