Detecting design or intent in nature

[Surgenator]

If I take the nylon example, the bacteria in the waste water pond develops the ability to break up a compound that NEVER EXISTED on planet earth before. The bacteria's cousins (non-waste water version) do not have this ability. So what do you conclude, an intelligence secretly engineered these bacteria to eat nylon? Or, did the bacteria evolved the property itself?

You are making a straw man argument. You are providing an observation of an evolutionary system operating without the involvement of an intellect. However the argument you are tasked with defeating is completely different....and your the observation you presented doesn't address it. You are tasked with presenting an observation of the implementation of an evolutionary system that did not require an intellect.

I agree that many evolutionary systems do not require the involvement of intellect once implemented. The spider sim example of one which does not require an intellect once implemented. In the spider sim the intellect sets up the system, then the intellect sits back and watches it run.

Remember that the claim you are addressing is Claim A: Only one of the following two propositions can be true:
Proposition 1: All evolutionary systems require intellect to be implemented
Proposition 2: Not all evolutionary systems require intellect to be implemented.

You are tasked with providing an observation that supports proposition 2. If the observation you present doesn't concern itself with implementation it fails to address either of the propositions.

There are no observations of the implementation of biological evolution that did not require intellect. The only observation of a biological system of evolution coming into existence is the one intellect Craig Venter and his team implemented.

First off, Chas is correct that evolution is not a system.
Second, I pointed out an obervation where no intellect was involved and yet see an overall change. If no intellect was involved, then no intellect was needed to implement the change. The lack of an intellect is inferred from the observations.
