Symposium: From small and squishy to big and armored: Genomic, ecological and paleontological insights into the early evolution of animals

The origin of animals and their early evolutionary history—culminating in the Cambrian ‘explosion’ when essentially all animal phyla appear in the fossil record within the geologically short span of ~20 million years—is one of the most exciting interdisciplinary topics in the biological sciences. Understanding why and how animals made the transition to multicellularity in the Tonian (~800 million years ago), and then suddenly appeared in the fossil record ~540 million years ago at the base of the Cambrian requires insights from phylogenetics, comparative genomics and morphology, evolutionary developmental biology, ecology, paleontology, and geochemistry. This symposium will explore these interdisciplinary questions with talks by experts in diverse fields from all over the world.
