Breakthrough study reveals how woolly mammoths and Arctic animals evolved their cold-weather superpowers over 3 million years ...

Polar bears are very closely related to brown bears, but have numerous key adaptations that help them survive in extreme arctic conditions. They have two layers of fur to help them keep warm and dry.

More specifically, the team found seven genes related to polar adaptation, four of which were fixed alleles in the polar bears. The comparison also showed that divergence was more gradual than ...

Is a polar bear really white? How much snow does Antarctica get ... The location and climate of both the Arctic and Antarctic regions are studied. Focus is on adaptations including physical and ...

Polar bears ... in the polar bear hair was critical from an anti-icing perspective. It also offers insight into some of the ways other animals living in polar environments have adapted to keep ...

The fact that most images of polar bears show them on land or ice says more about the practical difficulties faced by humans than it does about the bears' behaviour. With adaptations such as thick ...

Today, Lindqvist continues using genomic techniques to study the polar bear, with the goal of identifying genetic adaptations that help the animal survive brutal Arctic winters.

satellite collars have been the primary method used by researchers to study their behaviour and adaptation to the consequences of climate change. “Most of what we know about polar bear habitat ...
