Mammoths became extinct due to a sharp increase in humidity level, from which pasture large animals very quickly turned into swamps. This was reported by EurekAlert!.
Paleontologists studied the bones of large ice age animals throughout Eurasia and in America, and found that a significant increase in humidity of the environment occurred directly before many species suddenly became extinct about 11 to 15 thousand years ago. Constant humidity, resulting from the melting of permafrost and glaciers, has led to the extensive grasslands of the glacial period was quickly replaced by peat bogs and swamps.
“We did not expect such obvious signs of rising damp throughout Europe, in Siberia and the Americas. The timing of this event varies, but it always was accompanied by the disappearance of glaciers and permafrost and the extinction of animals,” – said study leader, Professor Alan Cooper.
Meadow fauna played a crucial role in the food chain. When the melting of glaciers provided the inflow of moisture, the ecosystem collapsed and many large mammals, including mammoths, became extinct.
March 3, 2017 it was reported that according to one scientists believe that mammoths became extinct as a result of genetic mutations.
