Abstract The transposable elementmariner has been found in many species ofDrosophilidae, several groups of Arthropods, and more recently in Platyhelminthes as well as in a phytopathogenic fungus. In the familyDrosophilidae, the distribution ofmariner among species shows many gaps, and its geographical distribution among endemic species is restricted to Asia and Africa. Amongmariner elements in species within and outside theDrosophilidae, the similarities in nucleotide sequence and the amino acid sequence of the putative transposase reveal many phylogenetic inconsistencies compared with the conventional phylogeny of the host species. This paper discusses the contrasting hypotheses of horizontal transfer versus ancestral origin proposed to explain these results.
