Wherever there is water, there are likely wild mink. (2018)[4] found no evidence for rapid bursts of lineage diversification at the origin of Mustelidae, and further analyses of lineage diversification rates using molecular and fossil-based methods did not find associations between rates of lineage diversification and Mid-Miocene Climate Transition as previously hypothesized. But Professor of Ecology at Aberdeen University, Xavier Lambin, said it was unlikely otters would win a final victory over the mink. Mink and otters look similar, but mink fur is cheaper and easier to work with. Helen Brown, of the Water of Leith Trust, said: “Otters could be the reason why there are less minks on the water.”.
