More support for a diderm (G-) PVC cell plan

A new publication related to the last post about a change of paradigm for the PVC cell plan, where Devos re-interprets the actual evidence in favour of a G- ancestry for PVC has just gone public. In this article that could be considered as an addendum to the TiM one, Devos re-considers in AvL the arguments presented by Fuerst as supporting the exceptional status developed in the AvL special issue dedicated to the first PVC conference. In this publication, Fuerst presented 5 major arguments that he claims warrant the exceptional status of the PVC cell plan. In this new publication, Devos re-interprets those arguments in an evolutionary context that was curiously missing from the Fuerst consideration. Devos considers an alternative interpretation grounded in evolutionary events that are likely to have shaped the PVC genomes. According to the author, this interpretation supports the alternative proposal that the PVC cell plan is derived from a Gneg one.

Apparently the two hypothesis are unreconcilable and future research in this exciting field should soon tell the truth from the unsupported claims.

Please leave a comment about your feelings on this issue. Hopefully this issue can be settled soon.
