Did you know trees may have caused a mass extinction when they evolved? 🌴 A new #Geology study suggests that an increase in productivity likely casued the widespread ocean anoxia (or ocean oxygen depletion) that contributed to the Late Devonian Mass Extinctions. What caused the increase in productivity? Well, this and many other studies point to the spread of trees on land. Trees and roots had evolved and rapidly spread in the Devonian, dramatically increasing rates of continental weathering an

The Devonian Mass Extinction was a turbulent, 20-million-year saga that eradicated Earth’s first forests and wiped out roughly 75% of all species. Are we on track for a repeat? Join lindsay_nikole and Colossal Biosciences for part two of our mass extinction series, as we explore the volcanic fury and oxygen-starved oceans that reshaped life on our planet forever.
