An underlying mechanism for one type of this process is modeled by the Bateson-Dobzhansky-Muller model. The most important model organism for this process is the three-spined stickleback. That mechanism is increased by "reinforcement", or the Wallace effect. Ernst Mayr proposed another type of this process after mapping the ranges of birds in New Guinea. Gould and Eldredge built on Mayr's theory when proposing that this process occurred during short periods in punctuated equilibrium. The two most common examples of this process result from reduction in gene flow or geographic isolation and are sympatric and allopatric. For 10 points, identify this process by which new species arise.
