Increasing species sampling in chelicerate genomic-scale datasets provides support for monophyly of Acari and Arachnida

Abstract

Morphological and molecular data have led to conflicting phylogenetic hypotheses for the Chelicerata. Here, the authors reconstruct the phylogeny of the Chelicerata using genomic-scale datasets, finding evidence for a monophyletic Acari and a single terrestrialisation of Arachnida.
