God's Anti-freeze

Job 12:7-8 But now ask the beasts, and they will teach you; and the birds of the air, and they will tell you; or speak to the earth, and it will teach you; and the fish of the sea will explain to you. A number of species of fish live, apparently comfortably, in Antarctic waters as cold as the freezing temperature of sea water, which is a couple of degrees colder than fresh water. This presents us with several mysteries. First, cold slows down the chemistry necessary for life. At these temperatures, life's chemistry all but stops. Second, from a creation perspective, how could fish created to live in a perfect, warm, comfortable world be able to live in an environment that makes life seemingly impossible? A team of biologists from Stanford University's Hopkins Marine Station have found some remarkable answers to these questions. The biologists studied an enzyme found in many creatures that changes a compound called pyruvate into lactate within the muscles. In the Antarctic fish, this enzyme appears to help this conversion take place at speeds usually only found in warmer creatures. It seems that the cold-water fish have a slight modification of this common enzyme that allows the enzyme to work more quickly despite the cold. And yes, researchers have also found the same modified version of the enzyme in a South American warm-water species. Antarctic icefish have no hemoglobin, an adaptation to the oxygen-rich waters of the Southern Ocean. Genes Hold Secret Of Survival Of Antarctic 'Antifreeze Fish' - http://www.sciencedaily.com/releases/2008/10/081016124049.htm ScienceDaily (Oct. 19, 2008) - A genetic study of a fish that lives in the icy waters off Antarctica sheds light on the adaptations that enable it to survive in one of the harshest environments on the planet. The study is the first to search the genome of an Antarctic notothenioid fish for clues to its astounding hardiness.
