Ontogenetic adaptation is an “ecological” concept in which mammalian maturation is seen as a coordinated sequence of specializations (stages) that enables the infant to survive within a sequence of distinct niches created by the parent(s) and the rest of the environment.
What are developmental adaptations?
Developmental adaptation refers to the ability of an organism to modify its phenotype in response to environmental exposures over the course of growth and development.
At what level does developmental or ontogenetic adaptation occur?
Developmental (or ontogenetic) adaptation occurs at the level of the individual during a critical period of growth and development, childhood especially. The capacity to make the change is inherited, but the change is not inherited and is not reversible.
Which of the following is an example of an ontogenetic adaptation?
Examples of ontogenetic adaptations are provided from the prenatal (e.g., placenta in mammals), infancy (e.g., nursing and rooting reflex; neonatal imitation), and childhood (e.g., overestimation of one’s abilities, egocentricity) periods.
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 are the phases of ontogenetic development?
A number of researchers have tried to detect these correlations in various ways but failed to successfully provide any proper association. Like human beings, the Wistar rats go through the ontogenetic developmental stages «Prenatal → Birth → Infancy → Childhood → Adolescence → Adulthood → Death».
What is an example of developmental acclimatization?
There is usually a “magic time window” of when the acclimatization can occur. This adaptation can take months to years to acquire. A famous example of this is those who have grown up at high altitude vs. those who have moved to high altitude as adults.
What are some examples of adaptation?
Examples include the long necks of giraffes for feeding in the tops of trees, the streamlined bodies of aquatic fish and mammals, the light bones of flying birds and mammals, and the long daggerlike canine teeth of carnivores.
What are the 6 types of adaptations?
What are the 6 types of adaptations?
Adaptation.Behavior.Camouflage.Environment.Habitat.Inborn Behavior (instinct)Mimicry.Predator.
What does the postnatal stage include?
The postpartum (or postnatal) period begins immediately after childbirth as the mother’s body, including hormone levels and uterus size, returns to a non-pregnant state. The terms puerperium, puerperal period, or immediate postpartum period are commonly used to refer to the first six weeks following childbirth.
What are examples of stressors during the prenatal stage quizlet?
Stressors during the prenatal stage include: smoking, alcohol, and drugs. 8. Children living at high altitudes develop a larger chest cavity by adulthood than children living at lower altitudes.
What are examples of stressors during the prenatal stage?
Increasingly, human studies are showing that stressful prenatal events such as intimate partner abuse, poverty, and food insecurity have enduring effects on the stress physiology of offspring, and that prenatal and early childhood stress can set the stage for lasting psychological and health challenges.
What is the difference between ontogeny and phylogeny?
Ontogeny refers to the development of an organism while phylogeny refers to how the organisms have evolved.
What are ontogenetic functions?
Ontogenetically, the parental role (apart from facilitating physiological development) is described in terms of shaping the responses of the offspring towards their physical and social environments.
How does evolutionary psychology explain human behavior?
Evolutionary psychology uses evolutionary theory to explain similarities in psychological characteristics. According to evolutionary psychologists, patterns of behavior have evolved through natural selection, in the same way that physical characteristics have evolved.
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 ontogenetic development as opposed to phylogenetic development )?
Ontogeny is a field of study that focuses on the aspect of the development of living organisms while phylogeny is a field of study that focuses on the study of the history of the evolution of a particular species. This is the key difference between ontogeny and phylogeny.
What is the difference between ontogeny and embryology?
As nouns the difference between ontogeny and embryology
is that ontogeny is the development of an individual organism while embryology is the scientific study of embryos.
