DNA code being switched on or off.
DNA is a very large molecule that encodes the
processes necessary for an organism to live and
reproduce. If parts of that code are altered, this
can cause structural changes—which, incidentally,
are almost always harmful. Many evolutionists
believe that given a long enough time, such small
changes can eventually result in the evolution of
vastly different organisms with new and different
body parts, thus constituting a new “order” of
animals or plants. But despite the claims of many
nature documentaries and science texts, this type
of evolution on any large scale has never been
observed. It is true that relatively small beneficial
single-gene mutations (i.e., affecting DNA that
encodes a single trait) can sometimes occur. An
example of this is seen in microorganisms that
by random mutations developed the enzyme
nylonase. (This allows them to digest nylon as a
food source.) However, nylonase is a relatively
simple protein, which does not even compare with
the amount or extent of massive DNA changes
needed for a fish to evolve into an amphibian—or
any analogous major changes in organisms. It is not
merely a matter of having enough time for many
small changes to accumulate. Even the smallest
