If a phylogeny were sufficiently clear-cut, then it could span large gaps in the record and establish evolution as fact. Yet life was designed as a biotic message. Life was designed to resist all naturalistic interpretations. Therefore the biomessage sender had to defeat the appearance of lineage. This was done with diversity.
Diversity is the antithesis of lineage.
Diversity destroys the semblance of lineage. Thus, even if there are might be good candidates, if one can' t pull out a single, direct lineage, it's not good. It's too broad to identify a specific lineage. I do not quite understand why it would be assumed that evolution follows a strictly linear and narrow sequence over a long period of time. Another way to falsify message theory would be to provide an example that spans life on a sufficiently large scale.
