All evolutionist efforts to establish beneficial mutations have ended in failure. In order to reverse this pattern, evolutionists have for decades been carrying out experiments on fruit flies, which reproduce very quickly and which can easily be subjected to mutations. Scientists have encouraged these insects to undergo all kinds of mutations, a great many times. However, not one single useful mutation has ever been observed.
It is a striking, but not much mentioned fact that, though geneticists have been breeding fruit flies for sixty years or more in labs all round the world—flies which produce a new generation every eleven days—they have never yet seen the emergence of a new species or even a new enzyme.186
. . . geneticists have subjected generations of fruit flies to extreme conditions of heat, cold, light, dark, and treatment by chemicals and radiation. All sorts of mutations, practically all trivial or positively deleterious, have been produced. Man-made evolution? Not really: Few of the geneticists’ monsters could have survived outside the bottles they were bred in. In practice mutants die, are sterile, or tend to revert to the wild type.187
In short, like all other living things, fruit flies possess specially created genetic information. The slightest alteration in that information only leads to harm.
