Sadly enough IC has not lived up to its claims and it is pretty clear that IC systems can arise gradually.
SJ: Indeed, building-in redundancy against a future contingency, is what one
would expect of a far-sighted Intelligent Designer, but not what one would
expect of a `blind watchmaker'.
On the contrary, what you see as contingency is the outcome of a natural selection process. What however is much harder to explain is junk DNA and other idiosyncracies.
Nope IC and ID have little to offer scientifically. Of course in the area of rethoric it excels with proponents such as lawyer Johnson. In science however it fails.
Not surprisingly.
