I was just listening to the History of English podcast episode that talked about the proto-IndoEuropeans, and he mentioned that the arrival of the lactase mutation in that population sometime around 3-4000BC was a large part (the other important piece was the domestication of horses) of what enabled them to dominate the central European steppes, which therefore gave their language the head start it needed to eventually become the forerunner of most European languages today.  He said that the lactase mutation also occurred independently (i.e. it's a different mutation but w/ the same result) in two other pastoral populations, among the Tuareg in Africa and among the camel-herding Arabs, and in all cases it allowed those populations to successfully expand and dominate their neighbors.
