There's no wise guiding force behind evolution. It's all guesswork.
So I don't see your point. It is really tuning for surviving within the constrains.
Let x be the set of all physical behaviors in nature. At any point in time, we (human beings) are aware of a subset of x, let us call it y.
When a human entity design a system, they can only use the behaviors in y. But an evolved system could potentially use all of x. Since y is always proper subset of x, this means that we will never be able to know everything required to safely modify an evolved system.
