Why did brown bears evolve into polar bears?
The researchers believe that the brown bear migrated to the north during a warmer climate period and when a cold period subsequently set in, a group of brown bears may have become isolated and therefore forced to quickly adapt to the new colder conditions.
Why do polar bears have black skin and clear fur?
Polar bears often appear white, but it’s all a trick of the light. Their skin is actually black (to better absorb the Sun’s warming rays), and their outer layer of fur is transparent. Under the glare of the Sun the see-through strands scatter light, and they change colour depending on the weather and time of day.
Why do polar bears have thick oily skin?
