Spiders form a monophyletic group with all modern spiders sharing a common ancestor. This means that all spiders are equally related to scorpions. Some stem groups may have characteristics that are plesiomorphic or "primitive with respect to other spiders" that may make them appear superficially similar to ancient arachnids.
