Lophophorata is monophyletic!
Super excited to see this work out in Current Biology - we sequenced a phoronid genome and used shared chromosome fusions to confirm the monophyly of Lophophorata.
A big team effort from the Luo Lab @yjluo.bsky.social!

Out now in Biology Letters, my latest paper tackles an apparently simple question: how many characters are needed to reconstruct a phylogeny? TL;DR: in most cases between 100 and 500, more than a substantial portion of morphological datasets, but the story is more complex... doi.org/10.1098/rsbl...

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...

The shells are vermetid gastropods, sedentary filter feeders characterized by loosening whorls that become progressively unwound, exploring regions of Raup's theoretical mollusk morphospace no snail explored before.
