Early Earth was a molten, asteroid-blasted hellscape. Scientists now know when that changed: « A new study narrows the timeline for the emergence of life on Earth. » Read Full Article #OriginOfLife #EarlyEarth #Astrobiology
🔬 New research in Nature Communications suggests conditions became optimal for an "RNA world" about 4.33 billion years ago, potentially marking a key stage in the origin of life.
💥 A 3D computer model simulating asteroid impacts found Earth's surface likely cooled enough for this RNA-based life stage between 4.4 and 4.3 billion years ago.
💧 This timeline aligns with zircon crystal evidence suggesting liquid water was present on Earth by 4.4 billion years ago, though other conditions like liquid water, nitrogen, and concentration methods are still needed for RNA chemistry.
