Roads as Drivers of Evolution (IMAGE) Dartmouth College Caption A suite of common ecological impacts of roads are shown as labeled arrows. While these effects are well described in road ecology, their role as known or likely agents of natural selection is poorly understood. Yet these factors are capable of driving contemporary evolutionary change. Studying the evolutionary effects of these factors will provide a more comprehensive understanding of the ways in which organisms are responding to the presence and consequences of roads.
