Yin et al use X-ray microtomography to show that the 609-million-year-old Caveasphaera develops within an envelope by cell division, ingression, detachment, and polar aggregation in a manner analogous to gastrulation; together with evidence of functional cell adhesion and development within an envelope, this is suggestive of a holozoan affinity. The image shows a life cycle of Caveasphaera and a simplified phylogenetic tree of Holozoa. Image credit: Yin et al, doi: 10.1016/j.cub.2019.10.057.
