Retroposed elements as landmarks of galliform evolution. Gray balls represent single retroposition events revealed by our search for CR1 and LTR elements in chicken and turkey sequence databases. Filled gray circles denote markers published by Kaiser et al. [12]. Supported splitting points are labeled with Arabic numerals. Triangles denote branches supported by indel markers (amount given by numbers above) present in the same loci as the retroposed elements. The taxa shown represent only those from which we sampled CR1 elements and LTRs. Significantly supported splitting points are indicated with * p < 0.05, **p < 0.0001.
