In the last decade and a half, advances in genetic sequencing technologies have
revolutionized systematics, transforming the field from studying morphological characters or …

The basal phylogeny of Chelicerata is one of the opaquest parts of the animal Tree of Life,
defying resolution despite application of thousands of loci and millions of sites. At the …

Deciphering the evolutionary relationships of Chelicerata (arachnids, horseshoe crabs, and
allied taxa) has proven notoriously difficult, due to their ancient rapid radiation and the …

High throughput sequencing and phylogenomic analyses focusing on relationships among
spiders have both reinforced and upturned long‐standing hypotheses. Likewise, the …

Long-branch attraction is a systematic artifact that results in erroneous groupings of fast-
evolving taxa. The combination of short, deep internodes in tandem with long-branch …

Genome-scale data sets are converging on robust, stable phylogenetic hypotheses for many
lineages; however, some nodes have shown disagreement across classes of data. We use …

The importance of morphology in the phylogenomic era has recently gained attention, but
relatively few studies have combined both types of information when inferring phylogenetic …

Spiders are important models for evolutionary studies of web building, sexual selection and
adaptive radiation. The recent development of probes for UCE (ultra‐conserved element) …

A prominent question in animal research is how the evolution of morphology and ecology
interacts in the generation of phenotypic diversity. Spiders are some of the most abundant …

Burmese amber is a significant source of fossils that documents the mid-Cretaceous biota.
This deposit was formed around 99 Ma on the Burma Terrane, which broke away from …
