A new study from the University of East Anglia suggests that polar bears are undergoing rapid genetic changes, and scientists believe it's due to the impacts of climate change.
“It’s kind of the first time that we believe we’ve seen a mammal system such as the polar bear, where temperature has been the lead cause, and environmental stress at increased temperature, is impacting their DNA, their genome in real time,” Alice Godden, the lead author of the study, told ABC News.
