In order to say that some function is understood, every relevant step in the process must be elucidated.

The trap does not work until all the parts were there. The system itself doesn't work until you fit all of them together.

As can be seen even by this limited number of examples proteins carry out amazingly diverse functions.

In many biological structures proteins are simply components of larger molecular machines.

The conclusion of design flows naturally from the data; we should not shrink from it; we should embrace it and build on it.

I believe the evidence strongly supports common descent. But the root question remains unanswered: What has caused complex systems to form?
