在节肢动物中发现的DNA介导的和RNA介导的类转座因子的简要描述和它们的分布审查。DNA介导的元素的分布模式是非常不规则的，主要原因似乎是宿主谱系之间的元素的水平转移。在水手元素的最佳记录案例中，这些宿主可以是不同的昆虫目，节肢动物纲，甚至其他动物门。RNA介导的元素似乎经历了更长的时间内的垂直进化的主机谱系，其水平转移的证据仍然很少。许多这些转座子的进化关系最近已经阐明了RNA介导的元件的逆转录酶的系统发育分析，并认识到一些DNA介导的元件的转座酶是在一些RNA介导的元件的整合酶远亲。
Transposable elements of the DNA-mediated and RNA-mediated classes found in arthropods are briefly described and their distribution reviewed. The distribution patterns of DNA-mediated elements are extremely patchy and the principal cause appears to be the horizontal transfer of elements between host lineages. In the best documented case of mariner elements, these hosts can be in different orders of insects, classes of arthropods, and even other phyla of animals. RNA-mediated elements appear to undergo much longer periods of vertical evolution within host lineages, and evidence for their horizontal transfer remains scant. The evolutionary relationships of many of these transposons have recently been illuminated by phylogenetic analyses of the reverse-transcriptase enzymes of the RNA-mediated elements, and the recognition that the transposases of some of the DNA-mediated elements are distantly related to in the integrases of some of the RNA-mediated elements.
