Can you give me an example of something not currently known but which is under study, that might produce evidence against design?
Let's re-employ Maxwell's little demon. We relocate him on the face of growing crystal and ask him, on the basis of the ongoing assembly of molecules from solution into the crystal form if the process is designed or random. "Random" he replies, being the demon that he is. In fact he insists that neither we nor our crystal growing apparatus exists, since at the crystal face he has no direct sense of us or apparatus -- just of solvent and solvate and the organized solid that grows beneath him. He calls us "just my imagination running overtime!"
Nothing at his level produces evidence against crystal evolution from randomness.
Still ... despairing and impatient we point out the orderliness of the crystal, and the "magical" occurance of solvent and solvate at just the right temparature and pressure and mix. "One of many possible circumstances, all equally possible, and this is no more than the one that happened to happen." he replies.
We study his intransigence, yet its origin is unknown to us. To Maxwell's career-changing demon it is that very stubborness which produces at his level an irrefutable evidence against design.
you ask: Can you give me an example of something not currently known but which is under study, that might produce evidence against design?
essay on my homepage lists a few..for most of them the evidence is already in but not accepted by all yet..
since evidences against design are in the essay, i think you mean evidences against multiple life origins instead..
..true evidence against multiple origins (aka evidence for common descent) would be if odds for one species becoming another were compatible with timeframe and randomness of event necessary..evo greatly overestimates the likelihood..
evo also assumes much evidences it which could equally evidence design, which is why we keep asking to teach them together, etc yawn
