The changing pace of insular life: 5000 years of microevolution in the orkney vole (Microtus arvalis orcadensis)
Island evolution may be expected to involve fast initial morphological divergence followed by stasis. We tested this model using the dental phenotype of modern and ancient common voles (Microtus arvalis), introduced onto the Orkney archipelago (Scotland) from continental Europe some 5000 years ago....
