What is ontogenetic development?

What is ontogenetic development?

Ontogeny is the development of a single individual, or a system within the individual, from the fertilized egg to maturation and death.1.

What are the periods of ontogenesis?

Ontogenesis is the period of realization of the genetic pro- gram of an individual’s development occurring under the effects of exogenic factors, the period of formation of the organism’s main structure and function, and the period of growth and formation of the reproductive capacity.

What is the difference between ontogenetic development and phylogenetic development?

Complete answer: The primary distinction among ontogeny and phylogeny is that ontogeny is the investigation of the advancement of living beings, while phylogeny is the investigation of development.

What is ontogenesis in biology?

(biology) the process of an individual organism growing organically; a purely biological unfolding of events involved in an organism changing gradually from a simple to a more complex level; he proposed an indicator of osseous development in children.

What is ontogenetic development How does it work?

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 the difference between an ontogenetic and a phylogenetic cause of behavior?

To clear things up, ontogeny is development while phylogeny is evolution. Scientists can either be on the side of ontogeny or phylogeny. Ontogeny is the study of the development of organisms while phylogeny is the study of evolution.

What is the difference between ontogenesis and the life cycle?

Ontogeny is the developmental history of an organism within its own lifetime, as distinct from phylogeny, which refers to the evolutionary history of a species. Ontogeny is used in anthropology as “the process through which each of us embodies the history of our own making.”

What is an example of ontogeny?

By studying ontogeny (the development of embryos), scientists can learn about the evolutionary history of organisms. 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.

What is the basic biogenetic rule?

The biogenetic law states that each embryo’s developmental stage represents an adult form of an evolutionary ancestor. According to the law, by studying the stages of embryological development, one is, in effect, studying the history and diversification of life on Earth.

What is phylogenetic behavior?

PHYLOGENETIC BEHAVIOR : Environment-behavior relations that are based on the evolutionary history of a species are called phylogenetic. The reflex is one instance of phylogenetic behavior. Species history provides the organism with a basic repertoire of responses that interact with environmental conditions.

How ontogenesis is used in anthropology?

Which is an example of an ontogenetic process?

Ontogeny is the development of a single individual, or a system within the individual, from the fertilized egg to maturation and death.1 As observed in several mammalian species, ontogenetic development of the intestine is an organized process driven by genetic and environmental factors that results in an adaptive,…

When does ontogeny take place in an organism?

Ontogeny (also ontogenesis or morphogenesis) is the origination and development of an organism (both physical and psychological, e.g., moral development ), usually from the time of fertilization of the egg to the organism’s mature form—although the term can be used to refer to the study of the entirety of an organism’s lifespan .

How is ontogenetic development related to social development?

Ontogenetic Development. Certain brain regions are also stimulated in a positive manner during attaching and rewarding social interpersonal interactions. If this expectation for social need fulfillment is breached, infants will likely stimulate stress neurocircuitry. This is accompanied by negative emotion (characterized by infant crying),…

How is the development of the intestine related to ontogeny?

Advances in cellular and molecular biology have allowed a better understanding of the mechanisms responsible for the ontogenetic changes of the mammalian intestine. The development of the gastrointestinal tract in the early stages of life is characterized by morphologic and functional changes of the intestinal epithelium.
