Modularity is the rule, not the exception in the design of life forms. Each piece has an existence largely independent of the other pieces. I am proposing that the absence of integrated design characteristics in life forms is scientific evidence against a designer who knew the ultimate purpose of the parts in life forms.
Back to the topic....
I believe this is confused thinking. Modularity is a good thing in human design - certainly it's at the core of software design. Modular systems are more flexible, more reliable, and more comprehensible, easier to develop.
If anything, I would expect a designer to produce a system that is more modular than evolution, where the only criterion is what works.
