Ambulacrariaに「歩帯動物」の訳が与えられていて嬉しい。

ちなみに普及度としては「水腔動物」の方が圧倒的ですが、個人的にはAmbulacrariaは「水腔動物」とは和訳すべきではないのかも？とも思っています。https://t.co/rYH8AOEkUr

TLDR: Support for deuterostome monophyly comes from sources of systematic error (branch-length, site-rate and site-compositional heterogeneity). When these are explicitly modelled, we cannot distinguish between monophyletic and paraphyletic Deuterostomia. (12/12)

Not a dumb question at all! On the contrary, this type of method has been tried a number of times (e.g. www.cell.com/current-biol... ). Definitely something to look at in the future!
Filtering artifactual signal increases support for Xenacoelomorpha and Ambulacraria sister relationship in the animal tree of life
Mulhair, McCarthy et al. explore the signal for alternative topologies relating to
the placement of Xenacoelomorpha. They determine that by filtering out genes whose
trees violate incontrovertible cla...

In 2010, Caron, Morris, and Shu gave this charming fellow the name of Herpetogaster collinsi, and placed it within the Deuterostomes, which represents an important step in the evolution of many modern day animals (e.g. humans, lizards, and sea cucumbers) 🧵 2/3

A wild guess, Ambulacraria?
Now I’m curious to find out the answer, too.

Today's random observation: excluding taxon: Vertebrata from a BLAST search on @ncbi doesn't actually exclude many vert sequences. And Ambulacraria is not in the taxonomy at all. Avoiding being spammed by vertebrates is unexpectedly complicated!
