The Evolution of Arthropod Body Plans: Integrating Phylogeny, Fossils, and Development—An Introduction to the Symposium

Abstract

The last few years have seen a significant increase in the amount of data we have about the evolution of the arthropod body plan. This has come mainly from three separate sources: a new consensus and improved resolution of arthropod phylogeny, based largely on new phylogenomic analyses; a wealth of new early arthropod fossils from a number of Cambrian localities with excellent preservation, as well as a renewed analysis of some older fossils; and developmental data from a range of model and non-model pan-arthropod species that shed light on the developmental origins and homologies of key arthropod traits. However, there has been relatively little synthesis among these different data sources, and the three communities studying them have little overlap. The symposium "The Evolution of Arthropod Body Plans—Integrating Phylogeny, Fossils and Development" brought together leading researchers in these three disciplines and made a significant contribution to the emerging synthesis of arthropod evolution, which will help advance the field and will be useful for years to come.
