Even given our somewhat limited knowledge of DNA, genetics and mutation, we can say that the following simple (and by no means exhaustive) evidences have not been found, but were they to exist in a system, I think we could strongly attribute genuine, active design ...
[1] A coding system for self-replicating organisms that did not admit of significant errors, by means of thorough error-checking which expressly prevents speciation.A coding system for self-replicating organisms that did not admit of significant errors, ie: self-correcting to the extent that any but the most minor variations could not occur. This would represent a genuine barrier to speciation.
Might it yet be discovered? Well, who knows what roles introns may play?
Nevertheless, the extent to which we can genetically modify organisms, the extent and impact of horizontal gene transfer, and the absence of any obvious post-zygotic barriers to gradual change suggest otherwise.
I suppose it would be possible to argue that such a self-correcting code could be the end point of an evolutionary process (which could go no further of course), but the presence of the same scheme of correction, preventing speciation, but found in many species contemporaneously, would be compelling.
To my mind, this is an area where creationists should be looking - far too many people pronounce that macroevolution is impossible without describing detailed, testable, mechanisms to prevent it. For my part, I wouldn't bother, as I see compelling evidence of speciation, but were I a transformed cladist, or a creationist who believed that species do not change, this is the field in which I would be researching for proof.
[2] The observed appearance of an irreducably complex biological structure in numerous members of a species in one generationThis is easy enough - a number of simple bacteria in lab conditions all develop flagella (au Behe) in a single generation. Just one bacterium doing it probably wouldn't convince me as I am endlessly impressed by their abilities to grab useful bits of DNA from here, there and everywhere.
Finally and most convincingly ...
