The authors examine factors affecting reproductive isolation in the early stages of speciation by collating data from 34 experimental speciation studies in 15 species ranging from yeast to vertebrates. They show that both phenotypic plasticity and divergent selection pressures accelerate the emergence of reproductive isolation, with plasticity promoting pre-mating isolation barriers in particular.
