Evolution![Figure][1] CREDIT: OYSTEIN WIIG, UNIVERSITY OF OSLO Polar bears are adapted to living in one of the harshest environments on earth, their range being determined by the extent of Arctic polar sea ice. They arose from the brown bear lineage and are most closely related to a group of genetically distinct brown bears that inhabit the ...

Nature, 1974
WHITE coloration of many animals in cold environments decreases the possibility of visual detection because of the lack of contrast between the animal and its white background. White hair thus provides concealing coloration for prey species such as arctic hare (Lepus arcticus), and for predators such as the polar bear (Ursus maritimus) and arctic fox ...

Polar bears can remain active throughout the year in air temperatures that range from +25°C to -50°C. Eskimos have long known that polar bear fur is both warm and hard-wearing, but exactly how it is so effective has recently been the subject of fierce debate.

This is the third in a trilogy of articles for NTQ addressed to the ‘noises off’ supplied by Shakespeare’s earliest co-stars: the baited bears that competed for trade, fame, and patronage for the duration of his career as an actor-playwright. ‘Shakespeare and the Three Bears’ (NTQ 106, May 2011) sketched this context, exposing as a canard, via a ...
