 However, if Rs result from gapless chains of natural causal processes, the evidential impact of those Rs again threatens to become problematic and ambiguous, since there will a fortiori be at the immediate level a full natural causal account for  them.[12]  Design will, in such cases, play no immediate mechanistic explanatory role, suggesting its superfluousness. But even if such conceptions were explanatorily and scientifically superfluous at that level, that does not entail that they are conceptually, alethically, inferential, or otherwise superfluous in general. The role of mind might be indirect, deeply buried, or at several levels of remove from the immediate production mechanism but would still have to be present at some level. In short, on the above picture Darwinian evolution will not meet condition (e) for explaining away design, which is not itself a shortcoming of Darwinian evolution.
