Nov 2, 2015 · Early researchers initially mistook fossils of these ancient bruins for polar bears, but subsequent investigation revealed a species related to the modern brown bear, albeit with broader...

Jun 7, 2022 · 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...

Mar 1, 2010 · Digging in the frozen tundra of Norway's Svalbard archipelago, scientists have uncovered the remains of the most ancient polar bear ever found. DNA analyses reveal that the bear—a mature male—lived about 120,000 years ago, at a time when wooly mammoths were also roaming the land.

Jun 16, 2022 · 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 Pleistocene, leaving a surprising amount of polar bear ancestry in the genomes of all living brown bears.

Nov 26, 2012 · How does the ancient distribution of polar bears – based on finds of natural-death remains (“fossils”) and bones found in archaeological sites – compare to the modern distribution of polar bears?

1 day ago · The Polar Bear, known scientifically as Ursus Maritimus, is still a majestic giant that roams the icy regions of the Arctic. These bears are well adapted to cold climates, with thick fur and a layer of fat to insulate them against the freezing temperatures. Polar Bears primarily hunt seals, using sea ice as platforms to catch their prey.

Mar 1, 2010 · 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...

May 6, 2022 · This historical compilation presents the record of known ancient polar bear remains from fossil and archaeological contexts before AD 1910. Locations of ancient polar bear remains described in the paper; some have multiple bone assemblages.

Jan 24, 2018 · A press release issued yesterday (23 January 2018) by the University of Stavanger tells the story of decades of work on the most complete ancient polar bear skeleton in the world, found in 1976 in southern Norway, that culminated in an articulated museum display.

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...
