Description. Ontogenetic development can be conceptualized as the portion of physical, cognitive, emotional, and social development that can be attributed to experiences with the environment and the individuals within the environment. In contrast, phylogenetic development refers to the portion of physical, cognitive, emotional, and social ...
Ontogeny. The initial stages of human embryogenesis. Parts of a human embryo. Ontogeny (also ontogenesis) is the origination and development of an organism (both physical and psychological, e.g., moral development [1]), usually from the time of fertilization of the egg to adult. The term can also be used to refer to the study of the entirety of ...
Ontogeny. In subject area: Neuroscience. Ontogeny refers to the changes in an individual's phenotype throughout its lifespan, influenced by a developmental program encoded in its genes, interactions with the environment, and maternal effects mediated through the egg. AI generated definition based on: Encyclopedia of Fish Physiology, 2011.
Nov 21, 2022 · Ontogenetic developmental processes begin at fertilization, in which a male and female gamete combine to form a complete set of DNA. From here, cells begin to rapidly divide. entering the first ...
Thus its development would reiterate its evolutionary history — ontogeny recapitulating phylogeny. This idea is an extreme one. If it were strictly true, it would predict, for example, that in the course of a chick’s development, it would go through the following stages: a single celled organism, a multi-celled invertebrate ancestor, a fish, a lizard-like reptile, an ancestral bird, and ...
ontogeny, all the developmental events that occur during the existence of a living organism. Ontogeny begins with the changes in the egg at the time of fertilization and includes developmental events to the time of birth or hatching and afterward—growth, remolding of body shape, and development of secondary sexual characteristics.
