An analysis of newly sequenced polar bear genomes is providing important clues about the species’ evolution, suggesting that climate change and genetic exchange with brown bears helped create the ...

As a species, polar bears have seen many ice ages. Rather than being a symbol of extraordinarily fast evolution, they’ve actually had plenty of time to adapt to life in the freezer. We have two ...

the find spurred decades of insight into the evolution of the polar bear. A new, high-resolution analysis of the DNA contained in that jawbone, published this week in Proceedings of the National ...

BUFFALO, N.Y. -- An analysis of newly sequenced polar bear genomes is providing important clues about the species' evolution, suggesting that climate change and genetic exchange with brown bears ...

Polar bears have become a poster child for the impacts of climate change on wildlife. Their future may be bleak but their past is altogether more glorious. Polar bears are an evolutionary success ...

And as it turns out, most of the polar bear's genes that have undergone rapid evolution seem to be involved in keeping its cholesterol under control and its heart from exploding under the strain.

A team of molecular ecologists at the University of Copenhagen, in Denmark, has found that polar bears developed unique features that allowed them to survive in a harsh, cold environment just ...

The study puts a timeline on the crisis for the first time as ice habitats melt. A dire new climate change report projects polar bears could reach extinction within the next 80 years, putting a ...

polar and black bear genomes to gain a better understanding of the paternal signature of bear evolution. They found evidence of extensive male gene flow that has led to the distribution of some ...

“It’s hard to look at polar bears and polar bear evolution without also looking at brown bear evolution and brown bears, because they are so closely related,” said Charlotte ...
