What mechanism explains why polar bears are white and bears found farther south have a darker color?

Since Polar bears live in arctic climates surrounded by ice and snow, over the years white fur was naturally selected in their population as a dominant trait that gave a competitive advantage. White Polar bears blend in more easily with their surroundings, enabling them to sneak up on their prey and make hunting easier. Non-white Polar bears eventually became extinct because of this hunting disadvantage. millmillhot321:well,actually their fur is actually not colored. their fur is see-through. it's like a little tube. it's white because of the sun. look up Polar Bears, a book on polar bears that's where i learend it.

∙ 6y ago- the fur is actually transparent optical fiber that carries light directly to the bear's black skin, helping to keep it warm
- camouflage to make the bear hard to see in the snow and ice

Polar bear's fur is white but their skin is black.
The reason why polar bear's fur is white because it helps them camouflage with snow.

What does Darwin propose as his mechanism for evolution?
Gradual changes via an unknown (at that time) mechanism, with natural selection weeding out individuals lacking specific adaptations. So, for instance... every so often we get hairless skinny bears. Well, heck, that's not pretty. And if the weather gets colder, then naturally they get "selected" out - meaning the poor unfuzzy bears don't tend to survive the colder winters in sufficient numbers cmopared to the fat hairy bears.

Why polar bears are get worried of globalwarming?
Their life style is directly connected to sea ice. They spend most of their life on sea ice and use it to hunt. Global warming is melting sea ice and causing all sorts of changes in the Polar bears behavior. Some bears are living farther north, and others are living on solid land longer. The bears which are living on land longer, are forced to fast as they only hunt on sea ice, and die more often.
