How can anyone look at our world and believe this all happened by chance? With just a glance at the animal kingdom and I see overwhelming evidence of design. Take the polar bear for instance. A polar bear that is tranquilized trapped, and released 300 miles away can usually find its way home. Even across drift ice that changes constantly and holds no landmarks and few odors. For years it puzzled researchers that polar bears never showed up on the aerial infrared photographs used in animal censuses. Yet both species showed up very dark on ultraviolet photographs, even though white objects normally reflect, rather than absorb, ultraviolet light rays. In 1978 a U.S. Army researcher discovered the reason. Polar bear hairs are not white at all, but transparent. Under a scanning electron microscope they appear as hollow tubes, without pigment. They act like tiny fiber-optic tubes, trapping the warming ultraviolet rays and funneling them to the bear’s body. At the same time the fur provides such efficient insulation that the bears outer temperature stays virtually the same as the surrounding ice which explains why bears do not show up on infrared photos.
