Maximum-likelihood tree for all 24 haplotypes of Barbary macaques and for 6 outgroup taxa. Bootstrap percentages recorded for maximum-likelihood full heuristic search (100 replicates) and maximum parsimony trees (5,000 replicates with fast stepwise addition option) are shown above major branches in bold and italics, respectively. Bayesian posterior probability values are presented below internodes. The haplotype numbers refer to those in Table 1. The population of Pic des Singes is divided between the Akfadou and Kherrata clades.
