they call it plant ontogeny or heteroblasty Using an experimental eucalypt forest of known pedigree and laboratory feeding trials, we examined the relative importance of plant ontogeny (heteroblasty), genetic variation among host trees, canopy height, and leaf age as potential drivers that could affect the distribution and feeding preference of a common insect herbivore, Chrysophtharta agricola. We found that ontogeny is a major factor affecting this insect. Its importance rivaled leaf physiological age, a well-documented factor, which served as our standard for judging the relative importance of other effects. Three patterns emerged: (1) In the field, beetle feeding was nine times greater in the adult zone than in the juvenile zone of heteroblastic trees (i.e., trees with both adult and juvenile foliage). (2) Laboratory feeding trials confirmed their strong preference for adult foliage. (3) Although eucalypt species, hybrid cross type (F1, F2, and backcrosses), and canopy height also exhibited significant effects on beetle feeding in laboratory trials, their relative importance was much less than ontogeny and leaf physiological age. We conclude that beetles perceive greater variation in host quality within individual plants than between different eucalypt species and their hybrids. The magnitude of these effects argues that ontogeny may rival other better studied plant traits that affect herbivores. We discuss how genetic regulation of phenotypic expression in plants may affect herbivore populations and structure communities.

What is the Simpler way to express ontogeny recapitulates phylogeny in language origins?
The phrase "ontogeny recapitulates phylogeny" suggests that the development of an individual organism (ontogeny) mirrors the evolutionary history of its species (phylogeny). In the context of language origins, this can be simplified to say that the way a child learns language reflects the stages of language development throughout human history. Essentially, individual language acquisition can echo the broader evolution of language itself.
What the evolutionary history of a species is its?
The evolutionary history of an organism is called its ontogeny. This is a study of biology that focuses on the origin of organisms.
What is the study of the origin and development called?
The study of the origin and development is called "ontology" or "ontogeny." This field examines the emergence and evolution of beings or entities.
Who said Ontogeny Recapitulate Phylogeny?
This statement means that the development of an individual organism (ontogeny) summarizes the development of the entire group of organisms (phylogeny). In other words, when we look at the stages of embryonic development of a human being we can see the stages of the evolution of mammals. The embryo starts as a single cell organism, changes to multicellular, develops gill arches, a single chamber heart that changes to a multichambered heart, etc.. Evolutionists theorize that these are the same stages in evolution.
What name is given to the process by which an organism develops from a single cell into may kinds of cells?
This process is called "cell differentiation." It is when cells become specialized to perform specific functions within an organism.
In the field of biology what is the meaning of the word ontogeny?
In the field of biology, the meaning of the word "ontogeny" is the development and origin of an organism. You can get more information about this at the Wikipedia.
What rhymes with progeny?
homogeny, ontogeny, phylogeny

The tail and gills in developing mammals?
Ontogeny recapitulates phylogeny
If two organisms look very similar during their early stages of development this is evidence that the organisms are what?
Of common ancestry, though ontogeny does not recapitulate phylogeny, ontogeny, development, can create phylogeny.
What is the difference between ontogeny and phylogeny?
Ontogeny refers to the development of an individual organism from fertilization to maturity, encompassing growth and differentiation of cells. Phylogeny, on the other hand, refers to the evolutionary history and relationships among groups of organisms over time, tracing their common ancestry and evolutionary changes.
What is the Simpler way to express ontogeny recapitulates phylogeny in language origins?

In the context of language origins, this can be simplified to say that the way a child learns language reflects the stages of language development throughout human history. Essentially, individual language acquisition can echo the broader evolution of language itself.
Who created the recapiculation theory?
" Ontogeny recapitulates phylogeny. " Ernst Haeckel. Now considered incorrect.
What major changes occur in a developing fetus during months 7-9 of pregnancy?
After ontogeny there is maturity.
What has the author Stephen A Schwartz written?
Stephen A. Schwartz has written: 'Differential aspects of ontogeny and oncology in-vitro'
What is ontogenetic skills?
Skills that depend primarily on learning and environmental opportunities. Extent to which any skill is mastered is dependent on Ontogeny.
