Islands often contain distinctive ecological conditions that can lead to unusual evolutionary trajectories such as dwarf mammoths and giant rats. In new research, scientists from the German Centre for Integrative Biodiversity Research and colleagues looked across living and extinct species from islands to determine whether these evolutionary oddities were more threatened and found that both dwarf and giant species were more at risk for extinction. Sardinian...
