The authors' analyses showed considerable discrepancy between the phylogeny of gypsy elements and the relationship of their host species, and they allow us to infer a complex evolutionary pattern that could include ancestral polymorphism, vertical transmission, and several cases of horizontal transmission.

Diptera, Drosophilidae: historical occurrence in Brazil
- M. S. Gottschalk, P. Hofmann, V. L. Valente
- Biology
- 1 November 2008
Drosophila was shown to be the most investigated taxon in the family, with the best resolved species distribution, and the low number of records of species from other genera indicates the paucity of studies specifically designed to investigate these species.
