It seems to be a core Creationist argument. I'm very interested to know of examples of genetic mutations that gave the creature a clear benefit, that left them able to breed, and maybe even added complexity to their genome.
Does the "fruit fly eating meat" example result from a change in genetic code or from a simple adaption to environment?
Change in genetic code, since the ability is inherited. Remember, "adaptation to the environment" refers to a
population, not an individual. For a population to become adapted, the genetics of a few or one individual has to spread so that every individual in the population has the allele or alleles (depending on whether the trait is in one gene or many genes).
