Have you never seen black and white camouflage?

I won't give you a flippant answer nor will I give you a thoughtful scientific answer. I assume that natural selection is not a perfectly smooth occurence. By being 500 pounds or whatever the weight a polar bear has it is not exactly inconspicuous to other beings around it. The white fur does keep it more camouflaged but not as camouflaged as it would be if it were a tiny two pound animal. Humans may have a rational principle that separate it from other animals but it is not hardly invincible to the forces of nature so mutations that are successful get replicated but also some mutations that are not ideal also get replicated as when a creature copulates he/she procreates with the whole extent of its genetic makeup. I am sorry for the polar bear that he does have a black nose but I am also sorry for humans for not being as furry as polar bears during the winter time. I guess I am being flippant. Interesting question. Thank you for posing it.

Humans hair is not the same color as their body usually. Polar bears have skin that is actually blact, but the white fur is s thick, it is hard to tell. Go to the zoo sometime and look at a polar bear that has been in a fight and you will see black skin.

when the polar bears are in danger they cover their black nose with their white paws, to camouflage themselves. However i think their noses are white because nature doesn't work in favour with everyone/thing. Or else you could say why where we created to have a very complicated/big brain out of all species?!

Camouflage very rarely has uniform color. Natural snow will have black dots -- dirt, twigs, dropping are everywhere. A black nose actually HELPS the bear blend in. An all white spot wil strand out more.

Because they do not have any fur on their noses, and if you dig through the thick layers of fur on their body, their skin is black. I also would tend to say, that polar bears really do not need to camouflage themselves from much of anything.

Polar bear fur is clear hollow tubes like fibreglass insulation, it only appears white. It's for warmth, not camouflage. It keeps them so warm that they have to swim in the cold water to keep from over heating.

in humans and all other mammals, nose and ears are the place where heat loss to the surroundings occur, as it is filled with thin walled capilaries.so, as black absorbs maximum amount of heat, the nose is black. they make up for this losss in camouflage bvy covering it witha paw while hunting.
now, how about that 10 points?

"because" black absorbs warm rays of light. Polar bears don't like getting a frozen nose.

Polar bears fur is actually translucent and funnels the ultra violet light down to the skin to create heat for them.
