“…Some cases of hybridization have been described for Platyrrhini (Table S1, Supporting Information), for instance recent hybridization between two species of howler monkeys in Mexico, with only fertile female hybrids . Furthermore, marmosets hybridize in anthropogenic and natural hybrid zones, and tamarin hybrids have been observed as well …”

Admixture, the genetic exchange between differentiated populations appears to be common in the history of species, but has not yet been comparatively studied across mammals. This limits the understanding of its mechanisms and potential role in mammalian evolution. The authors want to summarize the current knowledge on admixture in non-human primates, and suggest that it is important to establish a comparative framework for this phenomenon in humans. Genetic observations in domesticated mammals and their wild counterparts are discussed, and a brief global overview on other clades is presented. Based on this, some of the consequences of gene flow, including incompatibilities and their genomic footprint, as well as adaptive introgression are discussed, and suggestions for a functional genomics approach are made. It is proposed that the field is moving beyond descriptive observations in single species, to a comprehensive analysis of admixture and its impact. Admixture is becoming an integral part of mammalian evolution.

“…Experimental interspecific crosses revealed different levels of reproductive isolation between different species pairs, as captive C. jacchus × C. penicillata hybridized with relative ease, but physical anomalies such as blindness were common when other species pairs were crossed . The genus originated in the humid Atlantic Forest biome of southeast Brazil and migrated north to also occur in Brazil's savannah‐ and desert‐like semi‐arid biomes, with the six Callithrix species settling into allopatric distributions, and hybridizing naturally at distribution borders under secondary contact . Genetic and phenotypic accounts of natural Callithrix hybridization exist between four different Callithrix species pairings occurring along river barriers and in areas of ecological transition .…”

“…Genetic and phenotypic accounts of natural Callithrix hybridization exist between four different Callithrix species pairings occurring along river barriers and in areas of ecological transition . Relationships among Callithrix genomes are better represented by reticulating species trees as opposed to bifurcating ones, with divergence occurring under a scenario of speciation with gene flow . Thus, marmoset speciation also serves as a referential model of the splitting, subsequent contact and admixture of closely related lineages, a dynamic that was also important for recent human evolution.…”

“…Anthropogenic hybridization as a result of the illegal pet trade introduced Callithrix species from northern and central Brazil, particularly C. jacchus and C. penicillata , into other regions of the country and created artificial secondary contact with other exotic and native Callithrix populations (e.g., Malukiewicz et al; Malukiewicz et al; Mendes; Passamani et al). Although illegal and undesirable from a conservation biology perspective, the artificial introduction of marmoset into the ranges of existing species may provide unique insights into the effects of demographic differences in the hybridization process of ancient hominins, especially those that involved long‐range (and possibly rapid) movements of hominin groups into occupied territories, including the geographic radiation of Neanderthals into Asia (and probably North Africa) and the movement of ancient H. sapiens both within and out of Africa.…”

During the late Pleistocene, isolated lineages of hominins exchanged genes thus influencing genomic variation in humans in both the past and present. However, the dynamics of this genetic exchange and associated phenotypic consequences through time remain poorly understood. Gene exchange across divergent lineages can result in myriad outcomes arising from these dynamics and the environmental conditions under which it occurs. Here we draw from our collective research across various organisms, illustrating some of the ways in which gene exchange can structure

Endemic to the Atlantic Forest in Southeastern Brazil, the critically endangered Buffy‐Headed marmoset (Callithrix flaviceps) is lacking the required attention for effective conservation. We modelled its ecological niche with the main objectives of (1) defining suitable habitat and (2) prioritising areas for conservation and/or restoration. The current geographical range of Callithrix flaviceps in the Atlantic Forest of Southeast Brazil. We used Ensemble Species Distribution Modelling to define current habitat suitability considering four climate and two landscape variables. To identify areas to prioritise for conservation and/or restoration, we predicted future habitat suitability considering the intermediate (RCP4.5) and extreme (RCP8.5) climate change scenarios for the years 2050 and 2070. Among the variables included to predict current species distribution, tree canopy cover, precipitation seasonality and temperature seasonality were the most important whereas digital elevation model and precipitation during the wettest month were the least important. Callithrix flaviceps was most likely to occur in areas with tree canopy cover >80%, high precipitation seasonality and temperature seasonality between 21 and 23°C. From the future suitability prediction maps, the Caparaó National Park stands out as a likely key area for the preservation of the species. Furthermore, high climatic suitability but low landscape suitability suggests that habitat restoration in ‘Serra das Torres’ (South of the current distribution area) might be a useful strategy. However, creating ecological corridors on the west side of Caparaó would be necessary to improve connectivity. More surveys within and beyond the current geographical range are required to define more precisely the distribution of the species. Our results support the notion that seasonality is important for Callithrix flaviceps and that as a montane species, it prefers colder environments and higher altitudes. Within both climate change scenarios, Caparaó National Park was predicted to be highly suitable, with a high probability of presence.
