“…The strong skeletal similarities between Cercopithecus and Chlorocebus ultimately result from their similarity in body size and generalist adaptations, and are likely also due in part to their long history of hybridization (Aldrich-Blake, 1968;Detwiler, 2004Detwiler, , 2010Detwiler et al, 2005;Dugoujon et al, 1982;Sineo, 1990;Struhsaker et al, 1988;Tapanes, 2016). It is remarkable that even the unusually high variation in karyotype does not prevent these different species from hybridizing (Detwiler, 2019).…”

“…Unlike their papionin and other anthropoid relatives, cercopithecins have considerable variation in chromosome number, with diploid numbers ranging from 48 to 72 (Chiarelli, 1968; Dutrillaux, 1988; Lo Bianco et al, 2017; Moulin et al, 2008; Sineo, 1990). Hybridization is known to occur across species with different chromosome numbers (Dugoujon et al, 1982; Sineo, 1990). After the recent publication of the Chlorocebus reference genome by Warren et al (2015), Svardal et al (2017) reported high levels of admixture between Chlorocebus species that diverged during the Late Pleistocene.…”

Objectives: The goals of this study were to describe and interpret two new fossil assemblages of cercopithecin monkeys (n = 328), one from the Faro Daba beds (ca. 100,000 years) and the other one from the Chai Baro beds (>158,000 years old), in the Afar Rift of Ethiopia. Materials and Methods:We describe the two assemblages and compare them to extant cercopithecin species and the smaller fossil assemblage from Asbole, Ethiopia (ca. 600 ka). We use a population-based approach to the taxonomy given the unusually large number of specimens. Craniodental and postcranial anatomy are presented.Evidence of locomotor habitus is described and evaluated in a framework of hybridization and postcranial plasticity. Results:We attribute all cercopithecin specimens from both beds to cf. Chlorocebus and conclude that the Faro Daba and Chai Baro assemblages likely sample single species at each time horizon. Subtle differences between the two assemblages, mostly in postcranial morphology, are insufficient to justify separation at the species level.Discussion: The large sample sizes and unique preservational aspects of these two assemblages open a new window into the recent evolution of guenons. Our data indicate that these fossil populations may be ancestral to the cercopithecins currently living in the Afar region of Ethiopia.

“…Hybrid animals have been observed in the wild and in captivity between some taxa of Old World monkeys and gibbons, for example intergeneric hybrids between Papio × Macaca (Moore et al, 1999), Cercopithecus pogonias × Cercopithecus ascanius (Dugoujon et al, 1982), Symphalangus × Hylobates (Pellicciari et al, 1988). Among Prosimians, hybrids between species or subspecies were most commonly described in lemurs (Rumpler and Dutrillaux, 1976;Ratomponirina et al, 1982), for example Eulemur albocollaris × Eulemur fulvus rufus and Eulemur f. fulvus × Eulemur m. macaco.…”

We report on the cytogenetics of twin offspring from an interspecies cross in marmosets (Callitrichinae, Platyrrhini), resulting from a pairing between a female Common marmoset (Callithrix jacchus, 2n = 46) and a male Pygmy marmoset (Cebuella pygmaea, 2n = 44). We analyzed their karyotypes by multi-directional chromosome painting employing human, Saguinus oedipus and Lagothrix lagothricha chromosome-specific probes. Both hybrid individuals had a karyotype with a diploid chromosome number of 2n = 45. As a complementary tool, interspecies comparative genomic hybridization (iCGH) was performed in order to screen for genomic imbalances between the hybrids and their parental species, and between Callithrix argentata and S. oedipus, respectively. These genomic imbalances were confined to centromeric and telomeric heterochromatin, while euchromatic chromosome regions appeared balanced in all species investigated. When comparing marmosets and tamarins, sequence divergence of centromeric heterochromatin was already clearly noticeable. In the C. argentata and C. pygmaea genomes numerous subtelomeric regions were affected by amplification of different repetitive sequences. Cross-species FISH with a microdissection-derived C. pygmaea repetitive probe revealed species specificity of this repetitive sequence at the molecular cytogenetic level of resolution.

ABSTRACT. Serum proteins and RBC enzymes were surveyed in 16 species (183 animals) of African guenons (tribe Cercopithecini) in order to determine their genetic polymorphism and to establish dendrograms on the basis of their allele frequencies. The molecular data obtained were compared with those of mangabeys (16 animals tested) and discussed in the light of our results in Papio and Macaca. The species surveyed were Cercopithecus neglectus, C. hamlyni, C. l'hoesti (C. l'h. l'hoesti, C. l'h. preussi, and C. l'h. solatus), C. nictitans, C. mitis (C. m. kolbi, C. m. albotorquatus, C. m. stuhlmanni, and C. m . albogularis), C. cephus, C. ascanius, C. erythrotis, C. petaurista, C. mona, C. pogonias, C. wolff, and C. aethiops, Miopithecus talapoin, Allenopithecus nigroviridis and Erythrocebus patas, Lophocebus albigena, and Cercocebus torquatus.Eleven loci (ten systems) were studied in red blood cell enzymes and the Gc, Gin, Km, and Bm systems in DBP and immunoglobulin serum proteins. Most of the loci were polymorphic. Similar and different polymorphisms occur in closely related species or subspecies, particularly in Cercopithecus. Guenons have phenotypes clearly distinct from mangabeys.
