Ontogeny helps us understand evolution
WebOntogeny refers to the development of an organism while phylogeny refers to how the organisms have evolved. Let us take an example of a chicken, the ontogeny will explain the entire development cycle of the chicken right from the single cell. Now if we consider the example of an ostrich and assume that it descended from the family of chickens ... Webstudy of evolution results from the lack of a theory of development that is able to predict morphologies from patterns of gene activity. To date, theories useful for understanding …

WebA counter argument is developed here, namely that ontogeny is, at most, a process of stepped gradualism, with the ‘steps’ constituting both ontogenetic and phylogenetic ‘points of no return’. Truly saltatorial results are epiphenomena and not intrinsic parts of the actual ontogenetic process itself. The hierarchical nature of ontogeny ...
