Back to the errants and sedents - apparently.
Struck, Torsten H.et al. 2011: Phylogenomic analyses unravel annelid evolution. Nature 471(7336): 95-98. (Issue of 3 March)
There is a commentary by Detlev Arendt, http://dx.doi.org/10.1038/471044a
"... Many of the nodes in their tree, especially that separating the Errantia from the Sedentaria, had remarkably high support values (contrasting with those of previous annelid phylogenies based on single genes4), making it highly likely that this grouping is definitive."
This is of course would be somewhat of a nightmare return to the past for those of us who have to implement a higher classification for practical use.
Also this week Nature reports on the likely closure of Scripps Library.
