Indeed. I have not read through the whole post here, but based on the title, I think what I am saying is relevant :P

Our body makes lots of sense and evolution can be seen easily.[/quote]

In support to Frank's post, I do not think there is anything special about the human body, and why it is so. It is a perfect adaptation over a very long time, where adverse traits are bread out, and eventually we become highly specialized in our own environment.

Just like a bird is to flying, and a fish to water.

There is no need for a higher-order explanation. It works as it is.
