Though belonging to genera that have been distinct for several million years, gelada and common baboons—Theropithecus gelada and Papio hamadryas sensu lato, respectively—interbreed occasionally, even in the wild. [] Key Result The F1hybrids were large but developmentally normal. In skull and tooth form, and to a lesser extent in postcranial proportions, they were intermediate between the parental forms but lacked most of their parents' derived, (sub)species-specific epigamic characters. A female infant born…
Identifying the morphological signatures of hybridization in primate and human evolution.
Introgressive hybridization in southern African baboons shapes patterns of mtDNA variation.
TLDR
This work constructed a phylogenetic tree that separates representatives of the two southern African baboon species, yellow and chacma baboons, into six clades: southern, northern and eastern chacmas, Kinda baboons and southern and Luangwa yellow baboons.
Conservation Implications of Hybridization in African Cercopithecine Monkeys
TLDR
It is concluded that parapatric hybridization among closely related allotaxa is a widespread, usually natural process whose incidence may be modified by human influence.
Two Naturally Occurring Intergeneric Hybrid Snakes (Pituophis catenifer sayi × Pantherophis vulpinus; Lampropeltini, Squamata) from the Midwestern United States
TLDR
Two intergeneric hybrid snakes are described from the midwestern United States; one collected in south central Iowa and the other from southeastern Minnesota and both specimens are morphologically intermediate between the putative parental species P. c.
Hybridization in Large-Bodied New World Primates
TLDR
This work presents genetic evidence of hybridization of two large-bodied species of neotropical primates that diverged ∼3 MYA and shows that hybridization and subsequent backcrosses are directionally biased and that the only likely cross between parental species produces fertile hybrid females, but fails to produce viable or fertile males.
HYBRID ZONES AND SEXUAL SELECTION : INSIGHTS FROM THE AWASH BABOON HYBRID ZONE ( Papio hamadryas anubis x P . h . hamadryas )
TLDR
Data is presented on mate preference and intrasexual competition from hybrid baboons (Papio hamadryas ha-madryas x P. h. anubis) located in Ethiopia's Awash National Park as an example of sexual selection and its consequences in primate hybrid zones.
Is the New Primate Genus Rungwecebus a Baboon?
TLDR
This study clearly supports a close relationship between Rungwecebus and Papio and might indicate that the kipunji is congeneric with baboon species, however, it remains unclear whether all members of the new genus have been impacted by intergeneric introgression or rather only some populations.
Three Sykes's Monkey Cercopithecus mitis × Vervet Monkey Chlorocebus pygerythrus Hybrids in Kenya
TLDR
Three guenons, believed to be Sykes's monkey Cercopithecus mitis × vervet monkey Chlorocebus pygerythrus hybrids, are reported here; the first records of hybridization between these broadly sympatric species, as well as between these genera.
Hybridization in howler monkeys: Current understanding and future directions
TLDR
The extent of hybridization in the genus Alouatta is evaluated, the current knowledge of the genetic and morphological aspects of these hybrid systems are revised, and future directions in the study of hybridized within this genus are identified to understand the possible implications of the hybridization process in the evolutionary history of howler monkeys.
Alu insertion polymorphisms shared by Papio baboons and Theropithecus gelada reveal an intertwined common ancestry
TLDR
The discovery that several thousand Alu insertion polymorphisms are shared by T. gelada and Papio baboons suggests a much more permeable reproductive barrier between the two genera then previously suspected.

TLDR
Baboon diversity is used to explore some aspects of species definition and diagnosis, without attempting a comprehensive revision of the group or an exhaustive exploration of the species concept.
Characteristics of hamadryas-like male baboons living in anubis baboon troops in the Awash hybrid zone, Ethiopia.
TLDR
Long-term tracking of known immigrants indicates that they may reside for four years or more in their adopted troop, during which time they establish a series of comparatively short-term harems, and probably sire hybrid offspring.

TLDR
Comparison with fossils suggests that the Fayum parapithecids are not specially related to the Old World monkeys, while other undoubted Fayum 'hominoids' may share derived features with monkeys.

TLDR
A review and reanalysis of the morphological characters put forth by various researchers find little to contradict the consensus phylogeny derived from analysis of chromosomal banding, nuclear RNA restriction mapping, alpha and beta hemoglobin sequences, albumin and transferrin microcomplement fixation, DNA-DNA hybridization, repetitive DNA patterns, immunodiffusion, hemoglobin and adenylate kinase isozymes, and mitochondrial cytochrome oxidase subunit II DNA sequences.

Migration of male hamadryas baboons into anubis groups in the Awash National Park, Ethiopia
TLDR
It is found that the adult hamadryas males seem to immigrate at ages consistent with having left their host groups, and all but one of the cross-migrants appear phenotypically hamADryas.
Hybridization and introgression among species of sunfish (Lepomis): analysis by mitochondrial DNA and allozyme markers.
TLDR
The data suggest that absence of conspecific pairing partners and mating stimuli for females of rarer species may be important factors in increasing the likelihood of interspecific hybridization, and the maternal inheritance of mtDNA offers at least two novel advantages for hybridization analysis.
