Both creationists and evolutionists believe the evidence supports their theory and denies the other. Scientific creationists see evolution as a completely unscientific theory supported by insufficient evidence. They believe that much of the evidence used to support evolution actually supports creation. Therefore, evolution is the process that forms all life on Earth. Each species found on Earth today is a modified descendent of a previous species of organisms.
Evolution s most significant mechanism is natural selection.
By these observations, scientists have concluded that certain characteristics of organisms are hereditary. Because these organisms are able to reproduce, their traits are passed on to the next generation, which will then have a greater percentage of the desired trait. Although there were no documented cases of natural selection in Darwin s time, scientists have since amassed evidence that supports several instances of natural selection occurring in nature. To date, the peppered moth is the best example of natural selection occurring in the wild. At first, the peppered moth population consisted mainly of moths that were gray in color a few of these moths were black, but this trait was rare.
