Warming temperatures appear to be driving genetic mutations in some polar bears to help them survive the shifting climatic conditions.

Researchers say the findings, the first documented case of rising temperatures driving genetic change in a mammal, offer a "glimmer of hope" for the Arctic species, which is facing possible extinction this century.
