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.
The evolutionary history of an organism is called its ontogeny. This is a study of biology that focuses on the origin of organisms.

Not really. The phrase you are referring to is this. ' Ontogeny recapitulates phylogeny. ' Or, as you say, development repeats evolution. A reference to organisms going through all the ancestral evolutionary changes in their development. Which they don't. For instance, human foetuses do not have gill slits as fish do not have them. Both have pharyngeal pouches that develop into gills in fish and other jaw and throat parts in humans. So, you could more truly say, ' ontogeny creates phylogeny. '
answer difference between ontogeny and phylogeny?
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.
homogeny, ontogeny, phylogeny
Ontogeny
Ontogeny recapitulates phylogeny
Of common ancestry, though ontogeny does not recapitulate phylogeny, ontogeny, development, can create phylogeny.
No, they are not evidence for ontogeny recapitulating phylogeny.
" Ontogeny recapitulates phylogeny. " Ernst Haeckel. Now considered incorrect.

After ontogeny there is maturity.
