Abstract: By comparing animals to their closest living relatives, the choanoflagellates, we can reconstruct the biology of animal ancestors to illuminate how cellular and genetic changes contributed to the origin of animal development. Importantly, choanoflagellates express genes that are otherwise only found in animals, suggesting that the cellular and genetic foundations of animal development were in place before the emergence of animals. Furthermore, choanoflagellates differentiate into distinct cell types and morphologies, including multicellular colonies that resemble early stages of animal embryogenesis. Previously, the absence of reverse genetic tools in choanoflagellates stunted functional comparisons between choanoflagellates and animals. With the first tools that I have developed for performing transgenics, genome editing, and functional genomics, I will explain how a choanoflagellate species, Salpingoeca rosetta, now serves a simple model for investigating the origin and evolution of animal multicellularity.
