Phylogenetic reconstructions conducted using sequences of the DNA transposon Bari in the melanogaster group of Drosophila. (A) Phylogenetic analysis by maximum likelihood and (B) Network using the sequences of the transposase of the full-length copies obtained from sequenced genomes of the melanogaster group; (C) Network reconstructed using a region of the transposase sequenced in natural populations of the D. melanogaster and D. simulans species. In the network, full circles correspond to the sampled sequences; empty circles correspond to median vectors ancestral nodes, which represent lost sequences or sequences not sampled. Circle size corresponds to sequence frequency; branch size is proportional to the number of mutations that occurred, as indicated by the numbers above the branches.
