500 million years ago, Earth was vastly different from today. Days lasted 22 hours, the atmosphere was becoming breathable, and the average temperature was 10°C higher than it is now. There was no ice at the poles, and the planet was covered with warm seas. Life in the oceans began with microscopic forms, followed by strange and primitive creatures. The first complex organisms appeared around 560 million years ago; most were soft-bodied and employed various feeding methods, belonging to now-extinct species. #History #Life #Earth #Science #Planet #Oceans #Formation #Explore #Reels
