Scientists used advanced imaging to study a 380-million-year-old fish skull, revealing adaptations that shed light on how animals transitioned from water to land.

A 275-million-year-old animal, *Tanyka amnicola*, had a unique twisted jaw for grinding plants, challenging assumptions about early tetrapod diets.

New research reveals that temperature significantly influences animal immune systems, with implications for disease resistance as climate change alters global temperatures.
