There are many examples of this. Some are listed here .
As far as I know, most species of apes and humans are hearty enough and plentiful enough in population that we ought to see at least one or two examples where the distinction between the two has been difficult.
Discrete taxonomy in speciation is also an issue that has already been well addressed. read
Chimps are genetically similar to humans, but what you're suggesting would probably require them to be similar enough to (possibly) interbreed with humans; they are not that similar (separated by at least 6 million years of evolution).
Everything else you wrote makes me wonder if you've read the things I've written.
This isn't a research site. It's a discussion site. If you're not willing to answer any questions, then I've spent enough time here.
Those examples hardly demonstrate the magnitude of speciation necessary to explain the wider diversity of biological entities. Again, one would expect to find at least one or two living examples where a human might be confused for an ape. As far as I know, no such case has ever been documented. It's called absence of evidence.
Discrete taxonomy in speciation is also an issue that has already been well addressed.
I consider arguments from extinction also to be absence of evidence. It's a "maybe," not a "certainly so," and as such qualifies to be taught as some form of archaeological history and philosophy, not science in the strict sense.
And then there's the whole matter of evidence in general. Evolutionists are blythe in announcing the "huge amounts of evidence" to support their view, but science consists of more than mountains of evidence (the interpretation of which is subject to inestimable subjectivity). Testing, direct observation, repeatability, exploration, and the like must also be involved.
Looking at a static record and attempting to construct history therefrom is no more qualified to be called "science" than preaching the wrath of an Almighty God in a physics class is qualified to be called the proper application of theology. Science and theology are about, and engaged in, dynamic processes, the study of which leaves evolutionism in the dust as far as both truth and value are concerned.
