Climate change is causing more and more arctic mammals to mate with their parents.
Biologists explain that the rapid melting in the Arctic increases the chances of animals contacting, mating and mating with them, forming “hybrid children”.
This threatens the intact genetic resources of rare animals and puts them in danger of extinction.
In 2006, scientists were surprised to discover a cross bear between polar bears and grizzly bears. Earlier this year, another bear shot by hunters also had a mixed DNA pattern between polar bear and grizzly.
The phenomenon of global warming has affected the Arctic region two to three times more severely, altering the environments of dozens of characteristic mammals.
For polar bears, melting permafrost in the Arctic pushes them out of their usual feeding grounds, as they often use the edges of ice caps as a hiding place for seals.
