VII.2.4.1 Even a very low-intensity gene flow can prevent population
... Gene flow, that is the transfer of genes between populations, most commonly via migrating individuals, is an important factor in evolution. Depending on its intensity and on the structure of the population, it can either speed up evolution, or, on the contrary, slow it down significantly. Gene flow ...
