Journal ArticleDOI

The spider tree of life: phylogeny of Araneae based on target‐gene analyses from an extensive taxon sampling

TL;DR: A phylogenetic analysis of spiders using a dataset of 932 spider species, representing 115 families (only the family Synaphridae is unrepresented), 700 known genera, and additional representatives of 26 unidentified or undescribed genera is presented.
Journal ArticleDOI

Phylogeny of the orb-web building spiders (Araneae, Orbiculariae: Deinopoidea, Araneoidea)

TL;DR: While the spinning complement of single pairs of glands does not change much over the evolution of the group, multiple sets of glands are dramatically reduced in number, implying that derived araneoids are incapable of spinning many silk fibers at the same time.
Journal ArticleDOI

On missing entries in cladistic analysis

TL;DR: The exact algorithms of two commonly used parsimony programs, Hennig86 and PAUP, sometimes produce different solutions, and sometimes produce resolutions that are not supported by the data being analysed, causing discrepancies in the treatment of missing entries.
Journal ArticleDOI

Spider phylogenomics: untangling the Spider Tree of Life

TL;DR: Contrary to long held beliefs that the orb web is the crowning achievement of spider evolution, ancestral state reconstructions of web type support a phylogenetically ancient origin of the orbweb, and diversification analyses show that the mostly ground-dwelling, web-less RTA clade diversified faster than orb weavers.

Atlas of phylogenetic data for entelegyne spiders (Araneae: Araneomorphae: Entelegynae) with comments on their phylogeny

TL;DR: A phylogenetic analysis of higher groups of entelegyne spiders, with representatives of all enteleGYne families containing cribellate members and of Palpimanoidea, and a paraphyletic Araneoclada, excluding members of Haplogynae.
