Sponges are notoriously difficult to understand in evolutionary biology terms. I think this paper is a big step forward : www.science.org/doi/10.1126/...
Independent origins of spicules reconcile paleontological and molecular evidence of sponge evolutionary history
Sponges have a cryptic Ediacaran history because ancestral sponges were soft-bodied and had low fossilization potential.

Our work on the evolution of the regulatory genome of echinoderms is now out in @natecoevo.nature.com. Led by my former PhD Marta Magri, Danila Voronov & Saoirse Foley. Great collaboration of Arnone, Hinman & Maeso labs, started long time ago with our missed José Luis Gomez-Skarmeta: rdcu.be/eXX8l
Deep conservation of cis-regulatory elements and chromatin organization in echinoderms uncover ancestral regulatory features of animal genomes

Early sponges lacked [mineralised] skeletons.
New paper led by M. Eleonora Rossi. Great to have contributed alongside colleagues from @bristolpalaeo.bsky.social , @nhm-london.bsky.social and @mncn-csic.bsky.social.
