Comb jellies reveal conserved mechanisms behind animal body plans
Transplantation experiments conducted on comb jellies, one of the most evolutionarily distinct animal groups, have revealed that the mechanisms underlying tissue organisation during development are conserved across distantly related animals. The findings, published in Nature on 7 July 2026, shed new light on the deep evolutionary ancestry shared by animals. The research suggests fundamental body-plan rules emerged very early in animal evolution.
