What is ontogenetic development?
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.
What is an example of a behavior caused by ontogeny?
For example, chicks might “learn” to peck before hatching as a result of the rhythmic beating of their heart, or they might have a pecking reflex and simply learn to associate a food reward with pecking at the parent’s bill.
What are the stages in ontogenetic development?
Developmental stages. Development of an organism happens through fertilization, cleavage, blastulation, gastrulation, organogenesis, and metamorphosis into an adult.
What is a good example of ontogeny?
Learning about phylogeny from ontogeny For example, both chick and human embryos go through a stage where they have slits and arches in their necks that are identical to the gill slits and gill arches of fish. This observation supports the idea that chicks and humans share a common ancestor with fish.
What are the ontogenetic factors?
2 Ontogenic factors. Ontogeny is the entire arrays of process playing significant role in the generation of an organism. It commences from seeds and goes through several developmental events such as seedling, vegetative juvenile to maturing stage which lasts to the senescence stage.
What is ontogeny in psychology?
the biological origin and development of an individual organism from fertilization of the egg cell until death.
What is the importance of ontogeny?
Ontogeny is an important stage of an individual’s life history, and variation in growth trajectories and juvenile phenotypes has important consequences for a wide range of traits including behavioral traits that subsequently influence fitness, because they directly influence mating success or competitive interactions …
What are the three periods of ontogeny?
With this background, of special importance in the current account are three relatively distinct periods of ontogeny, each with its own set of adaptive challenges: (i) infancy and toddlerhood (before weaning, approximately 0–3 years); (ii) early and middle childhood (weaning to sexual maturity, approximately 4–12 years …
