The co-author of the analysis is Leslie Real, Emory professor of biology and Bozick's PhD adviser. One of the fundamental ideas in ecology is definitely isolation by distance: The further apart points are geographically, the more distant they genetically have a tendency to be. This idea applies to disease ecology in the cases of animals that do not travel definately not where they are born. Rabies spread by raccoons, for example, will generate a wave-like design of transmission across a geographic space. People, however, are a lot more mobile, traveling by rail often, road and air. The human mobility aftereffect of an epidemic stands out on the global scale starkly.
