mutations
In the twentieth century many genetic researchers tried to "accelerate evolution" by increasing mutation rates.12 This can be accomplished with ionizing radiation, like x-rays, or chemical mutagens. Researchers gave plants and fruit flies very high doses of radiation or other mutagens in hopes that new life forms, or at least improved organs, would result. Decades of this type of research resulted in repeated failure. Every mutation observed was deleterious to the organisms' survival. In the fruit fly research13 various mutations occurred--like legs coming out of eyes--but not one improved mutation was observed. Why? Because radiation is harmful, as the signs in hospitals warn pregnant patients. The pre-born child is more sensitive to mutagens, and thus has a higher likelihood of being harmed. "
this is also a good point
