It is clear that new [[gene]] [[alleles]] are accumulating in populations today, but there are two possible sources for these changes; mutations and intentional changes introduced by [[genetic recombination]]. The [[theory of evolution]] attributes the continued production of genetic diversity to mutations, but [[evolutionists]] overlook the fact that the [[cell]] was [[intelligent design|intelligently designed]]. The cellular machinery was programmed to perform a level of self genetic engineering, and is editing genes systematically through a process called so that organisms can [[adaptation|adapt]] to a wide variety of conditions. | It is clear that new [[gene]] [[alleles]] are accumulating in populations today, but there are two possible sources for these changes; mutations and intentional changes introduced by [[genetic recombination]].

Obviously mutations can indeed cause dramatic changes. Many experiments have been performed on fruit flies (Drosophila), where poisons and radiation induced mutations. However, the problem is that they are always deleterious. The Drosophila experiments showed an extra pair of wings on a fly, but these were a hindrance to flying because there are no accompanying muscles. Therefore, these flies would be eliminated by natural selection. | Obviously mutations can indeed cause dramatic changes.
