The ancient polar bear whose jawbone was retrieved in Norway carries enough unique genes to be a “sister group” to its modern counterparts. Still, says Lindqvist, it lived in the same place as ...

It is the only ancient polar bear skull ever recorded and the only ancient polar bear bone known from North America. (Photos by Pam Grove) Genomic analysis based on ancient DNA from Bruno’s skull ...

An analysis of ancient DNA from a 100,000-year-old polar bear has revealed that extensive hybridization between polar bears and brown bears occurred during the last warm interglacial period in the ...

DNA from a rare, ancient polar bear fossil is yielding information about the response of the species to the devastation wrought by past climate changes. Analyses of the fossil's DNA reveals key ...

DNA from a 110,000–130,000-year-old polar-bear fossil has been successfully sequenced. The genome, from a jawbone found in Svalbard, Norway, in 2004, indicates when polar bears (Ursus maritimus ...

“Very few polar bear fossils have been found, leading to widely varying estimates of exactly when and how polar bears evolved,” explains Øystein Wiig, polar bear expert and co-author at the University ...

Despite the name, Bruno was a female bear that lived somewhere between 100,000 and 70,000 years ago and its genome has helped scientists narrow in on this brown bear-polar bear divergence. The ...

There it was: an ancient Roman tomb weighing as much as a polar bear, peacefully preserved beneath the A47 road for over a millennium. Some coffee breaks turn out more memorable than others!

Its scientific name translates as the “polar bear lizard.” If Nanuqsaurus hoglundi, the tyrannosaur that roamed the ancient Arctic, were alive today, it could be forgiven for having an ...

We acquired samples of modern polar bear (1998-2007) obtained through hunting and we were able to compare them to samples from archaeological excavations conducted in the region.

The polar bear bones are about 5,500 years old, while the brown bear bones could be between 3,000 and 5,500 years old, scientists found after subjecting them to carbon dating.

A polar bear paleogenome reveals extensive ancient gene flow from polar bears into brown bears. Nature Ecology & Evolution , 2022; DOI: 10.1038/s41559-022-01753-8 Cite This Page : ...
