Did you know sponges are among the oldest animals on Earth? They're over half a billion years old!
New research has helped to narrow down when they first evolved - and it could reveal more about the first ever animals!

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.

Living sharks have innumerable tiny scales, but their earliest relatives somehow grew larger bony plates. In our new Biology Letters @royalsocietypublishing.org, we work try and out how, arguing they grew by fusing and remodelling spines and scales.
