17. Polar bears and humans have one thing in common. Despite the harsh environment polar bears call home, their layer of fur and blubber keep their body temperature steady at 37 C (98.6 F) – the same as humans. 18. They have an incredible sense of smell. Polar bears use their bionic...

Ancient humans, Neanderthals and Denisovans were genetically closer than polar bears and brown bears, and so, like the bears, were able to easily produce healthy, fertile hybrids according to a study, led by the University of Oxford's School of Archaeolo
With these techniques, it isn't necessary to physically catch bears, which can be stressful and dangerous for both bears and humans. Instead, researchers can look at sources of DNA dropped accidentally — environmental DNA. The person collecting the sample never needs to see or be seen by the...
36. Polar bears are non-territorial and their mating system falls within the category of “roving males”7. This means that males and females are distributed at low densities, and only consort during the mating season (March–May) when males actively search for females that signal receptiveness...
Interaction between polar bears (Ursus maritimus) and people is a growing concern for both bear conservation and human safety in a warming Arctic climate.
But even given the environmental context here, would polar bears stalk humans en masse, as they do in this book? It would take one heck of a perfect storm, but given a sufficient absence of luck future events could start to resemble this story. Whether real events would rack up ...
Polar bears have been extensively hunted, especially by Eskimos, for fur, flesh, and ivory, and they have declined greatly in numbers. Although extremely dangerous to humans, they do well in captivity. In recent years, changes in sea ice cover in the Arctic appears to have placed some popula...
