Polar bear evolution tracked climate change, new DNA study suggests
A whole-genome analysis suggests that polar bear numbers waxed and waned with climate change, and that the animals may have interbred with brown bears since becoming a distinct species millions of years ago.
New study suggests polar bears evolved earlier than previously thought
DNA links mysterious Yeti to ancient polar bear (Update 3)
A British scientist says he may have solved the mystery of the Abominable Snowman—the elusive ape-like creature of the Himalayas. He thinks it's a bear.
How do polar bears stay warm? Research finds an answer in their genes
(Phys.org) —In the winter, brown and black bears go into hibernation to conserve energy and keep warm.
DNA study clarifies relationship between polar bears and brown bears
At the end of the last ice age, a population of polar bears was stranded by the receding ice on a few islands in southeastern Alaska. Male brown bears swam across to the islands from the Alaskan mainland and ...
Ancient European bear had unusually large penis bone
Polar bear genome reveals rapid adaptation to fatty diet
A comparison of the genomes of polar bears and brown bears reveals that the polar bear is a much younger species than previously believed, having diverged from brown bears less than 500,000 years ago.
Ancestry of polar bears traced to Ireland
An international team of scientists has discovered that the female ancestor of all living polar bears was a brown bear that lived in the vicinity of present-day Britain and Ireland just prior to the peak of ...
Polar bear diet changes as sea ice melts
A series of papers recently published by scientists at the American Museum of Natural History suggests that polar bears in the warming Arctic are turning to alternate food sources. As Arctic sea ice melts ...
Superdaddy Pyros keeps Pyrenees bear numbers up
The number of bears roaming the Pyrenees remained stable at a minimum of 22 last year, thanks largely to the continued virility of Pyros, the undisputed daddy of the colony.
New insights into the evolutionary history of bears
According to researchers of the LOEWE Biodiversity and Climate Research Centre (BiK-F), Goethe University Frankfurt and the U.S. Wildlife Service several bear species that today only occur in America or in ...
Study yields 'Genghis Khan' of brown bears, and brown and polar bear evolution
Male bears are seemingly always on the prowl, roaming much greater distances than females, particularly for mating. For bear evolution, studying the paternally inherited Y chromosome is therefore a rich source to trace both ...
Limited connectivity among brown bear populations in Northern Europe
In a recent study, researchers have collected and analyzed brown bear samples from across Northern Europe. The estimation of gene flow points to a connectivity of the bears between Southern Finland and Western ...
Europe's bison, beavers and bears bounce back
Several European animal and bird species driven to near extinction by humans have made a dramatic comeback in the past 50 years thanks to conservation efforts, a report said Thursday.
