When the oceans died and life changed forever

The Late Ordovician Mass Extinction serves as a poignant reminder of how climate events can drastically alter biological trajectories. The survival of jawed vertebrates in isolated refuges illustrates the resilience of life, but also highlights the fragility of ecosystems in the face of rapid environmental change. This historical reset not only reshaped marine biodiversity but also set the stage for future evolutionary paths, emphasizing the interconnectedness of survival and adaptation.
