Description

How do fish survive in Antarctic waters without freezing? The answer is that their blood plasma has lots of ‘antifreeze’ protein that bind to ice and prevent the crystals from growing and thus causing damage. Some evolutionists claim that this is an example of ‘evolution in action’ because new DNA code has been created that codes for the antifreeze protein. But does this really support molecules-to-man evolution? Antifreeze proteins are quite different from the complex, specific proteins found elsewhere in the fish, or in our own bodies. They are simple proteins, which may have arisen through the duplication of a digestive enzyme gene that lost its original function due to mutations scrambling it. Even though they fortuitously prevent ice crystals from growing, this is a very non-specific job that many different random proteins could perform. So, even though antifreeze proteins help fish survive, they don’t explain how complex, specific proteins could arise by mutations.
