MtDNA phylogeny of baboons. Bayesian phylogram based on combined 'Brown region' and cytb haplotype sequences from 67 Papio individuals. Tip labels contain the unique identifier (number), the sampling site in form of a three-letter code as depicted in Figure 1 and country of origin of sequences within a haplotype. Colours indicate the traditionally recognized baboon species: brown = chacma, red = Guinea, grey = hamadryas, green = olive and yellow = yellow. Bayesian posterior probabilities and maximum-likelihood bootstrap values are depicted above the branches. A – G indicate the seven major clades, grey bars on the right indicate ten terminal haplogroups and the paraphyletic clade of southern yellow baboons.
