Primary phylogenomic analysis optimized against systematic error; support for Arachnida and Acari is dataset- and model-conditioned.

topology · contestedGenomic-scale chelicerate analyses using different taxon sets, slowly evolving genes, heterogeneous models and total evidence recover mutually incompatible monophyletic or paraphyletic Arachnida; one versus multiple terrestrializations and Cambrian–Ordovician timing are model-dependent historical reconstructions.
