Arachnida

Phylogenomic analyses sample the major arachnid orders and expose systematic conflict among data partitions at deep nodes. The evidence supports a contested sampled topology, not one settled arachnid tree, direct ancestor or temporal origin. This navigation entry is not a phylogeny or a complete taxon dossier.
