UH: Insular evolution: Large and big-footed voles in an outer archipelago

According to evolutionary theory, natural selection favours traits that enhance dispersal of populations to new habitats. The empirical evidence supporting this theory, however, is relatively scarce. A study carried out by researchers from the Faculty of Biological and Environmental Sciences of the University of Helsinki, along with their Swedish colleagues, reports rapid evolution of traits facilitating dispersal in an outer archipelago. The results was published today in the Proceedings of the Royal Society B biological research journal...
