farvningen
Farvningen, also known as the Great Dying, was a mass extinction event that occurred approximately 252 million years ago, marking the end of the Permian period and the beginning of the Triassic period. It is considered the most severe extinction event in Earth's history, with up to 96% of marine species and 70% of terrestrial vertebrate species becoming extinct. The cause of the farvningen is still a subject of ongoing scientific debate, with several hypotheses proposed, including volcanic activity, climate change, and asteroid impacts. The event is named after the Russian word for "withering" or "drying up," reflecting the widespread desiccation of the landscape during this period. The farvningen had profound effects on the Earth's biosphere, leading to a significant reduction in biodiversity and a long period of recovery for life on Earth. The event is also notable for the rapid recovery of life, with many groups of organisms returning to their pre-extinction levels within a relatively short geological timeframe.
