Multiple forms of selection shape reproductive isolation in a primate hybrid zone.

ABSTRACT: Speciation occurs when populations diverge and become reproductively isolated from each other. Natural selection is commonly accepted to play a large role in this process, and it has been widely assumed that reproductive isolation often results as a by-product of divergence driven by adaptation in allopatry. When such populations come into secondary contact, reinforcement can act to strengthen reproductive isolation, but the frequency and importance of this process are still unknown. Here, we explored genomic signatures of selection in allopatry and sympatry for loci associated with reproductive isolation using a natural primate hybrid zone. By analysing reduced-representation sequencing data, we quantified admixture and population structure across a howler monkey hybrid zone and examined
