caption_attribution_description: English: Molecular divergence time estimates treating Tetraophthalmi as stem-Cyphophthalmi. Ingroup clade sizes are not to scale. Numbers on nodes are in Ma.
context_page_description: Harvestmen are an order of arachnids often confused with spiders, though the two orders are not closely related. Research on harvestman phylogeny is in a state of flux. While some families are clearly monophyletic, that is share a common ancestor, others are not, and the relationships between families are often not well understood.
