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.
Antoine Étienne Renaud Augustin Serres
[His] theory applied to both vertebrates and invertebrates, and also stated that higher animals go through embryological stages analogous to the adult stages of lower life-forms in the course of their development, a version of the recapitulation theory later ossified in the statement "Ontogeny recapitulates phylogeny" of Ernst Haeckel.

The statement translates to "embryological development repeats evolutionary history"
The evolutionary history of an organism is called its ontogeny. This is a study of biology that focuses on the origin of organisms.
Growth and development of an organism. As with growth of adding new parts that then change very little.
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. '
PHYLOGENY
Binomial nomenclature and phylogeny both have to do with organisms. The former refers to the modern scientist's system for naming organisms. The latter is about how an organism evolved over time.
Of common ancestry, though ontogeny does not recapitulate phylogeny, ontogeny, development, can create phylogeny.
answer difference between ontogeny and phylogeny?
homogeny, ontogeny, phylogeny
"Progeny recapitulate ontogeny.", meaning that children have traits of their parents and other ancestors, all the way back to when humans arose.
Ontogeny recapitulates phylogeny
No, they are not evidence for ontogeny recapitulating phylogeny.
" Ontogeny recapitulates phylogeny. " Ernst Haeckel. Now considered incorrect.
"Progeny recapitulate ontogeny.", meaning that children have traits of their parents and other ancestors, all the way back to when humans arose.When Lily met Joseph, she tried hard to recapitulate the hour-long lecture into the 15 minutes that the two could spend together.

Ontogeny recapitulates phylogeny, or the development of the individual summarizes the evolution of the species. For example, human embryos go through a stage in which they develop gills as did their aquatic forerunners.
