New information on the origins of the Saimaa ringed seal: no close relatives of the Saimaa ringed seal are found in the present-day eastern sea orphans
In addition to the origins of the Saimaa ringed seal, a recent study has provided new information on the collapse of the genetic diversity of the Saimaa ringed seal.
The Saimaa ringed seal does not appear to be a close relative of the current eastern sea lions, as has been thought until now. According to new research, the evolutionary history of the Saimaa seal places it within the Arctic region, and more specifically within the North American seal group.
A surprising finding was revealed in a joint study by several Finnish universities and international research institutes. The evolutionary history of the Saimaa ringed seal was investigated using DNA from museum specimens.
The Saimaa ringed seal lives only on the Saimaa, where it is previously thought to have become isolated from other seals around 9,000 years ago, when land uplift cut off its route to the Baltic Sea at the end of the Ice Age. However, new research does not seem to support this view.
Also, the present-day Norse of the Viennese Sea, which are geographically the closest Arctic Norse to the Saimaa Norse, do not seem to be closely related to them. The same applies to the tile holder.
