Ontogeny (also ontogenesis) 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 adult. … Aspects of ontogeny are morphogenesis, the development of form; tissue growth; and cellular differentiation.
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 are the stages of ontogenesis?
Like human beings, the Wistar rats go through the ontogenetic developmental stages «
Prenatal → Birth → Infancy → Childhood → Adolescence → Adulthood → Death
».
What is the difference between phylogeny and ontogeny?
Ontogeny refers to the development of an organism while phylogeny refers
to how the organisms have evolved
.
What is Ontogenic 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
. … Some meta-analytic research on development (e.g., personality, social, emotional, etc.)
What is Ontogenic time?
Ontogeny (also ontogenesis) 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 adult
. … Aspects of ontogeny are morphogenesis, the development of form; tissue growth; and cellular differentiation.
What is human ontogeny?
The
process of individual development from a single cell
, an egg cell or a zygote, to an adult organism is known as ontogeny.
What is ontogenetic sequence?
Ontogenetic sequences are
a pervasive aspect of development
and are used extensively by biologists for intra- and interspecific comparisons. … This technique for discovering and formalizing sequences is called the “Ontogenetic Sequence Analysis” (OSA).
What is the basic biogenetic rule?
The biogenetic law states
that each embryo’s developmental stage represents an adult form of an evolutionary ancestor
. … The biogenetic law implied that researchers could study evolutionary relationships between taxa by comparing the developmental stages of embryos for organisms from those taxa.
What is ontogenetic behavior?
ONTOGENETIC BEHAVIOR
: Each organism has a unique life history that contributes to its behavior. Ontogenetic behavior is
due to events that occur over the lifetime of an individual
. Ontogenetic history builds on species history to determine when, where, and what kind of behavior will occur at a given moment.
What is the meaning of Phylogenic?
1.
The evolutionary development and history of a species or trait of a species or of a higher taxonomic grouping of organisms
: the phylogeny of Calvin cycle enzymes. Also called phylogenesis. 2. A model or diagram delineating such an evolutionary history: a molecular phylogeny of the annelids.
What is ontogeny plant?
Ontogeny refers
to the development of an organism through a series of discrete stages
. For plants, ontogenetic stages include seeds, seedlings, juveniles, mature and senescent individuals. Transition between stages can be difficult to identify, particularly when obvious morphological trait changes do not co-occur.
What is the difference between an ontogenetic and a phylogenetic cause of behavior?
In short, from a single existing organism it evolved into other animals, and phylogeny explains the evolution process. To clear things up,
ontogeny is development
while phylogeny is evolution.
What is used in Cladistics?
Cladistic methodologies involve the
application of various molecular, anatomical, and genetic traits of organisms
. … For example, a cladogram based purely on morphological traits may produce different results from one constructed using genetic data.
How is time represented in a cladogram?
A cladogram consists of the organisms being
studied, lines, and nodes where those lines cross
. The lines represent evolutionary time, or a series of organisms that lead to the population it connects to. Nodes represent common ancestors between species.
What is ontogeny in animal Behaviour?
Abstract. Ontogeny is
the development of a living being from the time the ovum is fertilized until the organism dies
. In ethology the development of behavior in the young is of special interest, i.e., the period from birth to the attainment of sexual maturity.
