on trees and support[edit]

There is an excellent likelihood that any newly published arthropod phylogeny will change -sometimes radically- certain groupings with varying degrees of support for each grouping (ML, Bayesian, etc) ranging from strong to insignificant. Rather than heedlessly cater to the phylogeny du jour, I argue this template should show some conservatism to better withstand future changes, and of course, facilitate reader navigation (the ultimate purpose of any navbox). In particular, the recent template changes to myriapods group Centipedes with Millipedes, a grouping based on a weakly supported tree in Miyazawa et al. (2014) who state that only the position of Symphyla is well-resolved, while "relationships among the remaining three classes could not be resolved due to low node support." I realize there is always room for debate about which tree or classification system to use, but urge that only well-supported schemes with strong, secondary support (e.g. multiple confirmation) be used when possible. I'm less familiar with recent advancements in pancrustacean classification, but my sentiments remain the same. If there is significant disagreement between multiple, well-supported trees, then perhaps it would prudent to eschew the hierarchical scheme and simply list descendent taxa (e.g. simply list all 4 myriapod classes unsorted, as was previously the case). FUTON bias and recentism bias should also be kept in mind.--Animalparty-- (talk) 21:34, 8 August 2014 (UTC)

Accoring to this review by Edgecombe et al. 2014 the consensus about crustacean phylogeny is close to the results of Oakley et al. 2013 (the source currently cited by the template), with the exceptions that there is no consenus for Thecostraca being closer to Copepoda than to Malacostraca, no consenus for a sister group relationship between Cephalocarida and Branchiopoda (because there is too little research about the relationships of Cephalocarida) and no consenus for a sister group relationship between Mystacocarida and Ichthyostraca sensu stricto (though I haven't seen any research contradicting it). The review also says that Pycogonida is likely sister to Euchelicerata.
For Hexapoda, the review by Kjer et al. 2016 says that the results of Sasaki et al 2013 (the source currently cited by the template) have not been subsequently corroborated. The review also says that Misof et al. 2014 is close to the current consensus but implies that there is not a strong consensus about the relationships among the four classes.

A short note, I would be very grateful if editors who know what is contained within this template could try and make it more readable. As a lay reader I can barely understand it at all. Some ways readability could be improved:

  • Remove special formatting (vertical text, 'small' and 'large' text)
  • Renaming the title to make it lay-reader friendly
  • Giving more prominence to terms lay readers are familiar with

I am sure editors have put a lot of effort into this template, for which I thank them, but it could be improved. Cheers, --Tom (LT) (talk) 01:00, 14 January 2015 (UTC)
