The recent literature does not support arms race models in spiders, but my preliminary data on nephilid spiders (Nephilidae Simon) suggest otherwise. Spiders are ideal for studying genital divergence because that is often the only salient trait that differ s; all others (life-history, reproduction) are thus held constant. Evolutionary questions are best asked in the context of a solid phylogeny. Here, we propose to test a new morphological phylogeny for nephilids (and thus the evolution of sexual traits) wit h genomic data. The combination of morphological and genomic data should provide the best context in which to analyse currently available behavioural evidence.The three lines of evidence together form the basis for a proposed long-term collaborative inter national research programme that unites three spider biology experts with different expertises. This project will reintegrate me into European science after six years of research in the USA. Spider genitalic evolution contrasts with better-known animal models, and may strongly challenge existing models of sexual selection and related evolutionary processes.
