The insertion site number of the retrotransposable element 412 was analyzed in natural populations of Drosophila simulans of worldwide origin by in situ hybridization. We observe a gradient in copy number ranging from as high as 23 in Europe to 1-10 in South Africa, while populations in Madagascar and the Indian Islands, which are the cradle of D. simulans, have only 3-7 copies. We find very different copy...
