New method yields provocative result: Only 600 ppm CO2 in the atmosphere when forests appeared
The greatest animal radiation on Earth was promoted by a stable marine redox landscape
The greatest rise in marine biodiversity in all of Earth’s history surprisingly was not fuelled by ocean oxygenation. Instead, oceanic redox stability appears to have favoured increased ecosystem resilience and – ultimately – a massive rise in global biodiversity levels. Oxygen rise occurred later… PhD student Alvaro del Rey measured the uranium isotope composition of … Read More
