Y-Chromosome and Mitochondrial Markers in Macaca fascicularis Indicate Introgression With Indochinese M. mulatta and a Biogeographic Barrier in the Isthmus of Kra

摘要: This is the first report of Y-chromosome introgression between primate species. We sequenced 3.1 Kb DNA and 1.5 mtDNA for 27 macaques Fooden's (Folia Primatol. [1976] 25: 225–236) fascicularis species group 5 outgroup taxa (Macaca sylvanus, Papio hamadryas, Theropithecus gelada, Allenopithecus nigroviridis, Cercopithecus mona). Phylogenies constructed separately paternal maternal data sets show a paraphyly among lineages Macacafascicularis, but mitochondrial monophyly same individuals. The topology depicts Indochinese Macaca haplotypes joining with those M. mulatta, followed by cyclopis fuscata, before clustering clade from peninsular Malaysia, Indonesia, Philippines. These contrasting patterns DNA, evaluated in context evolutionary consequences macaque sex-biased dispersal, present strong evidence contemporary hybridization mulatta Indochina biogeographic barrier Isthmus Kra.
