Can Polar Bear Adaptation Carry On?
Polar Bear adaptation to the cold and hostile Arctic climate is one of nature’s wonders. The ever-changing sea ice, where polar bear live, is one of the cruelest and most relentless climates on the globe. It’s only in modern evolutionary cycle that bears adjusted to arctic sea life. It started during the Ice Age, in the northern seas, when the seals needed to breathe and reproduce near the water’s surface. Because of this, the seals placed a copious year-round food source within reach of a population of brown bears, who then set out to inhabit the ice, changing into something akin to the polar bear of today, around 100,000 years ago. Weighing about 330 to 1,760 pounds, the length of the polar bear’s body is approximately 6.6 to 10 feet. The male body is generally larger than the female. The polar bear, like to the brown bear, is big and stocky. It has an long neck and small head. Its fur, normally white, sometimes appears yellow, due to oxidation.
