Antifreeze proteins prevent fish from freezing

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. To find out more from
