Catarrhini ancestral karyotype
(2n = 46)

Fission of primate ancestral chromosome form 3/21 Papionini (macaques, baboons;2n=42) highly conserved karyotypes (Wienberg et al. 1992) Cercopithecinae (guenons, 2n=44-72): fissions (Finelli et al. 1999) Colobinae (leaf eaters): similar to Papionini, but synapomorphic 21/22 and 1/19 in Asian species (Bigoni et al. 1996, 1998)
