Gene behind ‘evolution in action’ in Darwin’s finches identified

Screen Shot 2016-04-27 at 10.36.39 AMScientists from Princeton University and Uppsala University in Sweden have identified a specific gene that within a year helped spur a permanent physical change in a finch species in response to a drought-induced food shortage. The findings provide a genetic basis for natural selection that, when combined with observational data, could serve as a comprehensive model of evolution.
