Natural selection is the process of which nature selects organisms that are most fit to survive in a given environment. When an organism is born with a mutation or variation, which gives it a survival advantage, that organism is more likely to pass on its genes to a successive generation. As the theory goes, millions of years of these small changes being acted upon by this natural selection process, cause organisms to evolve into new types of organisms.
Natural Selection Only Selects
It’s important to remember that natural selection only selects organisms that have a survival advantage. Mutations or variations that give an advantage are necessary for the process to work. Mutations are necessary for new organisms to emerge.
Unfortunately, beneficial mutations that increase complexity and information have never been observed. These beneficial mutations are merely assumed to have happened. This is not observable science; rather it is taken on faith to have occurred in the past. All attempts to cause beneficial mutations for the purposes of evolving one organism into a new kind of animal have proved to be futile.
One such experiment has been running since the early 1900′s. Scientists have breed millions of generations of fruit flies while subjecting them to radiation and other mutation causing factors. When mutations occurred, the scientists would select the mutated fly and use it to reproduce future generations of flies. After simulating millions of years of evolutionary time with these fruit flies, scientists have been unable to produce anything other than fruit flies. In other words, mutations cannot produce new kinds of organisms.
