No, what I really mean is "Can an evolutionist provide a reasonable explanation for a gradual development of complex systems without presupposing something that is contradicted by direct empirical science. If system like eyes evolved through a gradual series of tiny steps then why does the step by step removal or deformation of eye components results in blindness and not in some simpler mode of vision? Presupposing that eyes evolved gradually without even considering this empirical question is what makes the evolution theory pseudoscience.
This would only be the case if changes consisted solely in adding new things on top; while everything that was already there remains the same.
If you turned off the internet then the company I work for would stop working. Everything that we do, every work process we have in place, every system that we use is reliant on a functional internet.
It would be silly from this to conclude that we always had the internet. Our company predates the internet, and there are people old enough to remember that. Since the internet became available, however, various organisational and technological changes have happened in our company; and they have all happened in an internet-capable environment. Therefore we've built a whole structure which is reliant on the internet, and which ceases to function without it.
I hope the analogy is clear.
