, that the embryological development of the individual repeats the stages in the evolutionary development of the species. For example, the beginnings of gill clefts appear in both humans and fish, but while they are elaborated and eventually function in the fish, in humans, except for the modified gill cleft that becomes the Eustachian tube, they disappear as the embryo develops. Though drastically modified and qualified since its proposal, the historical significance of this theory—"ontogenesis recapitulates phylogenesis"—is that with its appearance it lent support to the theory of evolutionevolution,
concept that embodies the belief that existing animals and plants developed by a process of gradual, continuous change from previously existing forms. This theory, also known as descent with modification, constitutes organic evolution.

Recapitulation

 

in biology, the repetition of the characteristics of remote ancestors in the ontogeny of existing organisms, specifically, in their structures, chemistry, and functions. The recapitulation theory was first formulated in 1859 by C. Darwin. The theory of phylembryogenesis, proposed by A. N. Severtsov, interpreted recapitulation in more morphological terms. The modern recapitulation theory was elaborated by I. I. Shmal’gauzen.

Recapitulation depends on the presence of a complex system of correlations in the organism and frequently manifests itself in the developmental peculiarities of interrelated organs and structures. Recapitulation results from shifts in the final formative stages of certain organs and not of the organism as a whole. These shifts represent extensions that arise from new correlations, which are introduced in ontogeny after the realization of basic morphogenetic processes.

There are many examples of recapitulation. In the embryos of land vertebrates, gill slits develop that correspond to the gill slits of their fishlike ancestors. In the ontogeny of higher vertebrates the succession of pronephros, mesonephros, and meta-nephros recapitulates the sequence of development of excretory organs in the phylogeny of their ancestors. In pteridophytes the dichotomous branching of their first fronds recapitulates the di-chotomous branching characteristic of their ancestors-Paleozoic psilophytes. During metamorphosis, the vision of frogs is dependent on the use of vitamin A2, just as in freshwater fish. By the time metamorphosis is completed, their vision is dependent on the use of vitamin A1, which is characteristic of land vertebrates.

2. Music the repeating of earlier themes, esp when forming the final section of a movement in sonata form

25) emphasized its presence as a purely structural device to divide the novel in half and found it tempting to think that the recapitulation would have headed the second of two papyrus rolls between which a copy of the novel would have been divided.
More recently, Whitmarsh (2009) has provided a very different reading of the recapitulation.
Whitmarsh's basic insight that the recapitulation is a marker of the plot's developing resolution is attractive, but I prefer to think that rather than simply implying the taming of complexity through recapitulation, Chariton imitated the Anabasis here to achieve very specific effects directly related to the larger correspondences between the novel and Xenophon's work.
Perhaps one answer is that the recapitulation is designed specifically to recall Xenophon so that a reader knows that the second, 'historical' half of Callirhoe will be modeled in the broadest sense on the Anabasis.
It is thus perfectly appropriate that Chariton has emphasized her ignorance again in 4,7,8, (38) just before the recapitulation in 5,1,1.
Cobet long ago saw another verbal imitation of the Anabasis soon after the recapitulation in 5,1,1.
Those readers who have either recognized the influence of the Anabasis all along or have had it brought home by the recapitulation in 5,1,1 will have the pleasure of having their expectations fulfilled in another 'aha
Book 8 begins with another recapitulation modeled on those from the Anabasis.

He also suggests that 'Schoenberg creates a double recapitulation that is analogous but in no way identical to the double exposition in terms of harmonic areas and thematic disposition' (p.
