How is that evidence for design?
Let me ask you this. Perhaps you've heard this one.
You are walking along a beach, and you happen across a working clock, which you pick up and examine. You ask yourself: was this clock designed? You decide that it almost certainly was, or how else could it be there? Could sand just spontaneously form into a clock?
So, you put the clock down, and notice it scurry away on little legs towards yet another clock. It mates with that clock...
The moral of the story is: it makes a great deal of difference to any issue of assembly just what sort of entity one is talking about. If it involves anything like replicating strands of DNA, then there might be a process of assembly that is not in any way like an airplane falling together.
