ethos said:I believe that you are speaking about natural selection here and not about evolution. I two believe in natural selection, the need for species to adapt to enviornmental circumstances, but not as evolution suggests that one species can evolve into an entirely different form. I am encouraged however to learn that you do believe in the inspired word of God.
Evolution is the process. Natural selection is one of its principal mechanisms. Adaptation is the outcome of natural selection. In certain circumstances adaptation leads to speciation.
Adaptation can lead to speciation when two groups of the same species become isolated from each other, each in a different environment. As each adapts to its own environment, it becomes more and more different from the other. If the differences are significant enough that the two groups will not interbreed with each other--even when the isolating mechanism is removed--then they are different species. This process has been observed many times. It has even been observed in labratory experiments.
Now, I am not sure what you mean by completely different form. But I can assure you that evolution requires that every child is of the same species as its parent. It may be however that a new child is not the same species as its ancestor of 4 or 5 million years ago.
