“…The recently reported intergeneric hybrid between C. mitis and Chl. pygerythrus (de Jong and Butynski 2010) extends the divergence time between hybridizing parental taxa to more than 7 myr for mtDNA genomes and more than 8 myr for nuclear genomes. Given that hybridization between these distantly related taxa can still occur today, we may speculate that repeated hybridization and extensive backcrossing among their ancestors might have contributed to the observed discordance between nuclear and mitochondrial phylogenetic trees.…”

Guenons (tribe Cercopithecini) are one of the most diverse groups of primates. They occupy all of sub-Saharan Africa and show great variation in ecology, behavior, and morphology. This variation led to the description of over 60 species and subspecies. Here, using next-generation DNA sequencing (NGS) in combination with targeted DNA capture, we sequenced 92 mitochondrial genomes from museum-preserved specimens as old as 117 years. We infer evolutionary relationships and estimate divergence times of almost all guenon taxa based on mitochondrial genome sequences. Using this phylogenetic framework, we infer divergence dates and reconstruct ancestral geographic ranges. We conclude that the extraordinary radiation of guenons has been a complex process driven by, among other factors, localized fluctuations of African forest cover. We find incongruences between phylogenetic trees reconstructed from mitochondrial and nuclear DNA sequences, which can be explained by either incomplete lineage sorting or hybridization. Furthermore, having produced the largest mitochondrial DNA data set from museum specimens, we document how NGS technologies can “unlock” museum collections, thereby helping to unravel the tree-of-life.

“…De Manuel et al 62 have shown that low levels of gene exchange between bonobos and chimpanzees continued between 550 and 200 kya after their original divergence, although bonobos ultimately contributed less than 1% to the Pan troglodytes genome. 41,43,44,67,68 However, few of these purported hybrids have been genetically confirmed 45 and some may have since been recognized as distinct species (e.g., Cercopithecus dryas, C. djamdjamensis). Under these circumstances, low-level hybridization could enable small, ill-adapted populations under intense selection to survive long enough to adapt to new habitat conditions.…”

The Cercopithecini, or African guenon monkeys, are one of the most diverse clades of living primates and comprise the most species-rich clade of Catarrhini. Species identity is announced by flamboyant coloration of the facial and genital regions and, more cryptically, by vigorous chromosomal rearrangements among taxa. Beneath the skin, however, these animals are skeletally conservative and show low levels of genetic sequence divergence consonant with recent divergence between congeneric species. The guenons clearly demonstrate that morphological, cytogenetic, and reproductive differentiation proceed at different rates during speciation. We review diverse kinds of data in an effort to understand this conundrum.

“…In addition to ongoing habitat disturbance, Kingdon [1997] assumed that C. djamdjamensis is additionally threatened by hybridization with the lowland forms C. aethiops and C. pygerythrus . Hybridization seems to be not uncommon within Chlorocebus as it has been reported from most species contact zones in East Africa, and even intergeneric hybridization with Cercopithecus mitis has been observed [deJong & Butynski 2010; Kingdon, 1997; Mekonnen et al, 2012; Napier, 1981]. However, with respect to C. djamdjamensis , both its taxonomic status and the potential threat by hybridization remain unclear without genetic analyses.…”

African green monkeys (Chlorocebus) represent a widely distributed and morphologically diverse primate genus in sub-Saharan Africa. Little attention has been paid to their genetic diversity and phylogeny. Based on morphological data, six species are currently recognized, but their taxonomy remains disputed. Here, we aim to characterize the mitochondrial (mt) DNA diversity, biogeography and phylogeny of African green monkeys. We analyzed the complete mitochondrial cytochrome b gene of 126 samples using feces from wild individuals and material from zoo and museum specimens with clear geographical provenance, including several type specimens. We found evidence for nine major mtDNA clades that reflect geographic distributions rather than taxa, implying that the mtDNA diversity of African green monkeys does not conform to existing taxonomic classifications. Phylogenetic relationships among clades could not be resolved suggesting a rapid early divergence of lineages. Several discordances between mtDNA and phenotype indicate that hybridization may have occurred in contact zones among species, including the threatened Bale monkey (Chlorocebus djamdjamensis). Our results provide both valuable data on African green monkeys’ genetic diversity and evolution and a basis for further molecular studies on this genus. Am. J.
