Genetic analysis showed that Norwegian lemming appeared only 35 thousand years ago – it makes one of the youngest species of mammals in the world.
The new DNA study found that Norwegian lemming – the little resident of the tundra – only 35 thousand years ago.
Scientists have found that the animal was formed as a species before the climax of the last ice season. It makes one of the youngest mammals on the planet.
The results of the study published in the journal Prochedings of the National Academy of Sciences are described at Phys.org, shows a unique path of developing this species. Thanks to the DNA compliance and comparison of the Genoms of nine modern and two ancient lemmings, scientists have found that Norwegian and Siberian lemmings come from different evolution lines that do not cross themselves. It distinguishes them from many other mammals, which usually have traces of shock.
Norwegian lemming is a major link to the fenniscandia tundra ecosystem, which serves the main food for predators such as the Arctic Fox. Scientists have also discovered the way – unique mutations in its genes – they can explain the characteristic black and yellow color, adaptation to cold and winter activity, helping to prevent predators.
“Work is a significant step for our understanding of the speculation and evolution of lemmings. It gives way to the way for the future research, in particular ancient Gen and accurate dating of the emergence of unique genetic adaptations of Norwegian lemmings,” says Co -Author of the Work of Pag -Love Dalen.
Earlier it was reported that scientists from the University of East Tennessee have made a unique discovery, giving you a look to look at a fresh view of the evolution of amphibians.
