From: Resolving kangaroo phylogeny and overcoming retrotransposon ascertainment bias
Kangaroo and wallaby maximum parsimony phylogeny inferred from retrotransposon data. Dark red circles represent retrotransposon markers. Clades for which there is no retrotransposon information (shown here without red dots) were then resolved in agreement with phylogenetic analyses of both nuclear and mitochondrial DNA sequences3,4,39. ML support values are obtained from an independent analysis3 that utilized nuclear genes, for comparison with the retrotransposon markers. Shaded rectangles represent the genus Wallabia (light blue) and the Macropus subgenera (orange). Coloured vertical bars (C1 – C8) each represent a retrotransposon marker that conflicts with the majority based on parsimony inference, and indicate alternative groupings of taxa (e.g. conflict bar C1 supports a grouping of M. eugenii + M. agilis + M. parma + M. rufogriseus + W. bicolor to the exclusion of M. irma and other macropods). Identified presences and absences are respectively marked (+) and (−) or unmarked if data is missing. Outgroup species are Onychogalea unguifera, Lagorchestes hirsutus, Thylogale thetis and Lagostrophus fasciatus. Marker indexes refer to Table 2, and are numbered i) to viii), with iii) and iv) both summing markers along two branches. The location of the markers is based on Sanger sequencing and scoring filled and empty sites from PCR amplification patterns (Supplementary Table S3, Figure S3a,b).
