For some reason, this is not a question that evolutionary biologits ask alot. Can you guys put a number on this? What other part of the story isn't being told?
Evolution does not pretend to provide a complete, step-by-step list of 'microspecies' lined up one after the other from primordial sludge to human. (Or from fish to mammal, or from photoreceptor to eye). It is a general process, which has been observed and which, if it is accepted, explains a huge variety of natural phenomena, including speciation and the peculiar way in which living organisms are well suited to the environments in which we find them. If we are to reject this theory, it will be because there is a theory which explains what we see better and more parsimoniously.
If a theory predicts A,B and C it is not a disproof to say "Where's X, Y and Z?"

And as soon as we try and enter a quantitative estimate, no matter how loose, then a great deal of puzzlement starts to intrude into the otherwise sunny picture. Let's say 50,000 changes are required, and that's probably a conservative estimate from what i've read. Where are the other 49,000+ sequential changes? Doesn't Darwinian theory hold that changes are incremental and small?
This doesn't even make sense - presumably he's claiming there are 50,000 changes in DNA - those aren't going to show up in the fossil record.

After all, we're not talking about changes that are arbitrary. A creature must have these changes if it's expected to survive in the open ocean, and we don't see these changes in the transitional record.
This is also ambiguous unless, as anticipated, we're back to the "Part of an eye doesn't provide any advantage" claim which has been demonstrated to be false and is equally false when applied to the gradual changes required for a sea-dwelling creature to evolve into a land-dwelling one.

Having said that, Ambulocetus is probably the best find in support of evolutionary theory, but you must ask the other tough questions in order to reach the next step in the development of the scientific theory. These questions are not being addressed.
You still haven't said what you think the theory of evolution actually is. (Or darwinian theory as that plagiarised post labelled it).
You have declared it false, then demonstrated many times that you don't understand what it actually claims. Science is amazing and evolution is a really brilliant explanation for what we find in the world - why dumb reality down just because it makes you uncomfortable for some reason?
