Darwinism has been dead for a long time, my friend. Its called The Theory of Evolution now. It is based loosely on Darwins work in the Galapogos and later. But all this really did was open up intrigued minds to other possibilities besides a conscious creator. Many other people have worked on the idea since and it is their work that scientists today think of when hearing the term 'evolution'. You come across to me as if you think that scientists adhere to the strict idea of evolution that darwin layed out. That's ancient stuff, even if its too hard to believe for someone who thinks that the absolute truth of the universe was layed out in a book written two thousand years ago. Evolution occurs naturally in all things. This is what they mean when they say that it benefits the scientific theory. Think about it. Something doesn't work to its maximum efficiency. So if some part of it changes a little bit, it works more efficiently. Unless it works less efficiently, at which point it loses ability to maintain its niche (think of a particular model of car, or a computer program). If it doesn't change at all, then other things will change and become more efficient, causing it to be less efficient relatively, even though it doesn't change.
